00:00:00.000 --> 00:00:02.399
Welcome back to the Deep Dive. This is where

00:00:02.399 --> 00:00:04.679
we strip away the noise, take a stack of dense

00:00:04.679 --> 00:00:07.559
sources, and pull out the absolute clearest,

00:00:07.559 --> 00:00:09.740
most surprising insights you need to be truly

00:00:09.740 --> 00:00:12.779
well -informed. And today, we are tackling a

00:00:12.779 --> 00:00:16.859
giant. A huge project. Cracking open the life

00:00:16.859 --> 00:00:19.559
and legacy of Thomas Alva Edison. Right. And

00:00:19.559 --> 00:00:21.980
that name, it just instantly brings up the image

00:00:21.980 --> 00:00:25.100
of the Wizard of Menlo Park and, you know, the

00:00:25.100 --> 00:00:27.500
light bulb. But that's a bit like judging a whole

00:00:27.500 --> 00:00:29.600
planet by its atmosphere. It's the first thing

00:00:29.600 --> 00:00:32.020
you see, but it's not the whole story. Not at

00:00:32.020 --> 00:00:34.299
all. We're looking at a figure who, you could

00:00:34.299 --> 00:00:37.320
argue, literally invented the modern concept

00:00:37.320 --> 00:00:39.939
of organized industrial science. He created the

00:00:39.939 --> 00:00:41.880
first industrial research laboratory. He wrote

00:00:41.880 --> 00:00:43.840
the playbook. He absolutely wrote the playbook

00:00:43.840 --> 00:00:46.149
for innovation. for managing teams and for this

00:00:46.149 --> 00:00:48.810
kind of relentless systematic testing that got

00:00:48.810 --> 00:00:52.130
him, what, an astonishing 1 ,093 U .S. patents.

00:00:52.369 --> 00:00:54.090
That number is just staggering. So when we say

00:00:54.090 --> 00:00:56.210
deep dive on this one, we really mean it. We

00:00:56.210 --> 00:00:59.210
are going way beyond the light bulb. We're exploring

00:00:59.210 --> 00:01:03.350
his entire industrial reach from telegraphy and

00:01:03.350 --> 00:01:07.310
power distribution to things you just wouldn't

00:01:07.310 --> 00:01:10.620
expect, mining. Cement. And the foundational

00:01:10.620 --> 00:01:12.900
elements of the music and film ministries. Exactly.

00:01:12.939 --> 00:01:15.879
Our mission today is to look at his, let's say,

00:01:15.920 --> 00:01:19.140
controversial business practices, the truly unexpected

00:01:19.140 --> 00:01:22.420
side ventures, and maybe most fascinating of

00:01:22.420 --> 00:01:25.019
all, the deep fundamental paradoxes that really

00:01:25.019 --> 00:01:27.920
defined him. Because that's the core of it, isn't

00:01:27.920 --> 00:01:30.379
it? Yeah. The central contradiction is just stunning.

00:01:30.519 --> 00:01:33.079
Here's a man who is self -educated, almost completely

00:01:33.079 --> 00:01:35.819
deaf. And yet. And yet he revolutionized sound.

00:01:36.239 --> 00:01:38.879
light and the power distribution systems, I mean,

00:01:38.900 --> 00:01:40.780
they literally shape the world we live in today.

00:01:40.879 --> 00:01:43.120
That tension between his own limitations and

00:01:43.120 --> 00:01:45.079
his world -changing inventions, that's the thread

00:01:45.079 --> 00:01:46.840
we're going to be pulling on. Okay, let's unpack

00:01:46.840 --> 00:01:49.120
this. Time to start at the very beginning. Thomas

00:01:49.120 --> 00:01:51.939
Alva Edison was born in 1847 in Milan, Ohio,

00:01:52.200 --> 00:01:55.180
but he really grew up, came into his own in Port

00:01:55.180 --> 00:01:57.560
Huron, Michigan. Now, we always hear the simple

00:01:57.560 --> 00:02:00.280
story that he was self -educated, but what did

00:02:00.280 --> 00:02:02.760
the sources actually tell us about how he built

00:02:02.760 --> 00:02:04.849
his knowledge? What was the foundation? Well,

00:02:04.909 --> 00:02:07.230
the key is that his education was systematic,

00:02:07.549 --> 00:02:09.629
even if it wasn't formal. I mean, he only went

00:02:09.629 --> 00:02:11.750
to school for a few months. A few months. That's

00:02:11.750 --> 00:02:15.030
it. His mother, Nancy Matthews Elliott, she was

00:02:15.030 --> 00:02:17.689
a former school teacher, and she took over. She

00:02:17.689 --> 00:02:21.069
taught him the basics, reading, writing, arithmetic.

00:02:21.430 --> 00:02:23.500
So it was a homeschool environment. Exactly.

00:02:23.659 --> 00:02:25.879
And that self -guided approach was fundamental

00:02:25.879 --> 00:02:29.139
because it let him just dive into whatever interested

00:02:29.139 --> 00:02:33.340
him most without the rigid structure of a 19th

00:02:33.340 --> 00:02:35.520
century classroom. And what grabbed his attention

00:02:35.520 --> 00:02:39.180
was science and philosophy. Absolutely. The foundational

00:02:39.180 --> 00:02:41.639
text, the book that really lit the fire, was

00:02:41.639 --> 00:02:44.639
called A School Compendium of Natural and Experimental

00:02:44.639 --> 00:02:46.740
Philosophy. What was in it? It was packed with

00:02:46.740 --> 00:02:49.159
instructions for basic experiments, stuff you

00:02:49.159 --> 00:02:50.840
could do with materials that were easy to find.

00:02:51.199 --> 00:02:54.439
And for Edison, this was it. It immediately led

00:02:54.439 --> 00:02:56.960
him to start tinkering with electricity, with

00:02:56.960 --> 00:02:59.139
chemistry. He wasn't just reading theories. He

00:02:59.139 --> 00:03:01.159
was reading a manual. It was a how -to guide

00:03:01.159 --> 00:03:03.139
for immediate application. He wasn't learning

00:03:03.139 --> 00:03:05.259
passively. He was using the book to do things.

00:03:05.740 --> 00:03:08.560
But it wasn't just the technical stuff. The sources

00:03:08.560 --> 00:03:10.979
also point to the philosophical framework he

00:03:10.979 --> 00:03:13.580
got from his parents. They were big readers of

00:03:13.580 --> 00:03:16.219
Thomas Paine. And that's a key piece of context

00:03:16.219 --> 00:03:19.159
that so often gets missed. The influence of pain

00:03:19.159 --> 00:03:23.060
meant he was grounded in this tradition of rationalism,

00:03:23.080 --> 00:03:25.819
of skepticism, what people at the time called

00:03:25.819 --> 00:03:29.139
scientific deism. So a very questioning, logical

00:03:29.139 --> 00:03:31.900
approach to the world. It instilled in him this

00:03:31.900 --> 00:03:35.020
fiercely independent way of thinking that you

00:03:35.020 --> 00:03:37.500
see throughout his entire career. He didn't just

00:03:37.500 --> 00:03:40.580
invent things. He approached every single problem

00:03:40.580 --> 00:03:44.969
with this analytical, almost skeptical. And that

00:03:44.969 --> 00:03:47.409
intellectual curiosity, it turned into entrepreneurial

00:03:47.409 --> 00:03:50.409
energy almost immediately. Let's talk about his

00:03:50.409 --> 00:03:54.150
first real side hustle, the train job. He started

00:03:54.150 --> 00:03:56.560
so young. Around age 12, he was a news butcher

00:03:56.560 --> 00:03:58.479
on the trains running between Port Huron and

00:03:58.479 --> 00:04:01.400
Detroit, selling newspapers, candy, vegetables

00:04:01.400 --> 00:04:03.280
to the passengers. And this wasn't just a kid's

00:04:03.280 --> 00:04:06.219
job. It was his first business. A self -run business,

00:04:06.419 --> 00:04:08.860
and he was wildly successful at it. The sources

00:04:08.860 --> 00:04:10.900
show that by age 13, he was turning a profit

00:04:10.900 --> 00:04:14.719
of $50 a week. $50 a week in the 1860s. That's

00:04:14.719 --> 00:04:17.160
an enormous amount of money for a child. It's

00:04:17.160 --> 00:04:19.310
a fortune. And where did all that capital go?

00:04:19.730 --> 00:04:21.610
Right back into the engine of his curiosity.

00:04:22.009 --> 00:04:24.949
He funneled every penny into buying more equipment

00:04:24.949 --> 00:04:26.790
for his electrical and chemical experiments.

00:04:27.069 --> 00:04:29.389
He even had a lab on the train, right? He did.

00:04:29.509 --> 00:04:31.810
He managed to set up a small laboratory in the

00:04:31.810 --> 00:04:34.910
baggage car. And as if that wasn't enough, he

00:04:34.910 --> 00:04:37.829
also founded his own newspaper, the Grand Trunk

00:04:37.829 --> 00:04:40.629
Herald. Yes, and this is where you see his early

00:04:40.629 --> 00:04:43.939
grasp of production and distribution. He wasn't

00:04:43.939 --> 00:04:46.139
just selling papers. He was publishing his own.

00:04:46.279 --> 00:04:49.459
He put out 24 issues. How many subscribers did

00:04:49.459 --> 00:04:51.920
he have? He managed to get 500 subscribers and

00:04:51.920 --> 00:04:54.420
even hired two assistants to help him. So think

00:04:54.420 --> 00:04:57.519
about that. By age 15, he is already managing

00:04:57.519 --> 00:05:00.079
people, controlling content, and mastering market

00:05:00.079 --> 00:05:02.699
demand. The whole systematic view of production

00:05:02.699 --> 00:05:05.199
was there long before Menlo Park ever existed.

00:05:05.459 --> 00:05:07.560
That entrepreneurial engine was firing on all

00:05:07.560 --> 00:05:09.740
cylinders, but his health was starting to falter.

00:05:10.589 --> 00:05:12.610
Let's get into his deafness, which started developing

00:05:12.610 --> 00:05:15.199
around age 12. Yeah, the historical consensus

00:05:15.199 --> 00:05:18.519
the most likely cause was a severe bout of scarlet

00:05:18.519 --> 00:05:21.660
fever and then these recurring untreated middle

00:05:21.660 --> 00:05:24.199
ear infections. It was a gradual, persistent,

00:05:24.459 --> 00:05:27.220
physical reality he just had to live with. But

00:05:27.220 --> 00:05:29.420
that reality, that was a little too simple for

00:05:29.420 --> 00:05:31.500
the showman in him. He made up these elaborate,

00:05:31.680 --> 00:05:33.519
kind of ridiculous stories about it. Oh, all

00:05:33.519 --> 00:05:35.980
sorts of tales. Like a conductor boxing him on

00:05:35.980 --> 00:05:38.279
the ears or lifting him by them. He was always

00:05:38.279 --> 00:05:40.879
keen on controlling the narrative, even about

00:05:40.879 --> 00:05:43.199
his own body. Why do you think that was? It speaks

00:05:43.199 --> 00:05:45.769
- to his need for control, I think, and maybe

00:05:45.769 --> 00:05:48.410
an unwillingness to just admit a simple vulnerability.

00:05:48.870 --> 00:05:50.970
But the fascinating part, the really crucial

00:05:50.970 --> 00:05:54.550
part, is how he internalized it. He reframed

00:05:54.550 --> 00:05:56.769
this handicap as an asset. And here's where it

00:05:56.769 --> 00:05:58.889
gets really interesting. As an adult, he was

00:05:58.889 --> 00:06:01.610
adamant that his hearing loss was a gift, that

00:06:01.610 --> 00:06:04.370
it allowed him to avoid distraction and concentrate

00:06:04.370 --> 00:06:07.750
with this just extreme focus on his work. Imagine

00:06:07.750 --> 00:06:10.170
trying to run a chaotic research lab full of

00:06:10.170 --> 00:06:13.189
machinery and experiments. The wizard essentially

00:06:13.189 --> 00:06:15.930
had built -in noise -canceling headphones. It's

00:06:15.930 --> 00:06:18.709
an incredible thought, and it led to these unique

00:06:18.709 --> 00:06:21.250
ways of experiencing the world, especially music.

00:06:21.660 --> 00:06:23.480
He wouldn't just sit and listen. That wasn't

00:06:23.480 --> 00:06:25.439
his experience of sound. He would physically

00:06:25.439 --> 00:06:28.519
clamp his teeth into the wooden frame of a piano

00:06:28.519 --> 00:06:31.540
or later a phonograph to absorb the sound waves.

00:06:31.740 --> 00:06:34.519
The vibrations. Correctly into his skull. It

00:06:34.519 --> 00:06:37.319
shows this powerful, almost desperate desire

00:06:37.319 --> 00:06:40.060
to connect with the very vibrations he was trying

00:06:40.060 --> 00:06:42.839
to capture and record with his inventions. It's

00:06:42.839 --> 00:06:45.670
an astounding paradox. The great orchestrator

00:06:45.670 --> 00:06:47.689
of modern sound was experiencing it primarily

00:06:47.689 --> 00:06:50.089
as a physical vibration through his skeleton.

00:06:50.389 --> 00:06:52.670
And you have to believe that physical experience

00:06:52.670 --> 00:06:55.430
informed the sensitivity he built into his audio

00:06:55.430 --> 00:06:58.649
inventions, especially the phonograph. He knew

00:06:58.649 --> 00:07:01.910
intimately how mechanical vibration translated

00:07:01.910 --> 00:07:04.990
into perceived sound. So his career in telegraphy

00:07:04.990 --> 00:07:07.649
really kicked off in 1862 after this moment of

00:07:07.649 --> 00:07:10.629
heroism. He saved a child from a runaway train

00:07:10.629 --> 00:07:12.910
car. Right. And the Grateful Father, who was

00:07:12.910 --> 00:07:15.209
a station agent, trained him as a telegraph operator

00:07:15.209 --> 00:07:17.769
as a reward. He worked the night shifts from

00:07:17.769 --> 00:07:20.889
1863 to 1869, which was perfect for him. Because

00:07:20.889 --> 00:07:23.110
it gave him time to study. Exactly. He was just

00:07:23.110 --> 00:07:26.350
soaking up knowledge. Spanish. Qualitative analysis

00:07:26.350 --> 00:07:28.529
and, of course, the mechanics of electricity.

00:07:29.230 --> 00:07:33.149
But his incessant tinkering, it sometimes got

00:07:33.149 --> 00:07:36.149
in the way of his actual job. Famously so. There

00:07:36.149 --> 00:07:38.389
was that famous incident where he was fired from

00:07:38.389 --> 00:07:41.370
the Grand Trunk Railway after a near train collision,

00:07:41.589 --> 00:07:43.870
which was the direct result of one of his side

00:07:43.870 --> 00:07:46.649
experiments. So this era was crucial, though.

00:07:46.870 --> 00:07:50.029
It taught him the power and the limitations of

00:07:50.029 --> 00:07:53.079
electrical communication. By 1869, he's in New

00:07:53.079 --> 00:07:55.139
York City and he gets mentored by a man named

00:07:55.139 --> 00:07:58.079
Franklin Leonard Pope. Right. And they co -found

00:07:58.079 --> 00:08:00.540
an electrical engineering company. And already

00:08:00.540 --> 00:08:02.819
you can see his focus is on system improvements.

00:08:03.100 --> 00:08:06.000
There are manufacturing machines to record telegraphs,

00:08:06.000 --> 00:08:08.100
typewriters that printed directly onto the wire.

00:08:08.259 --> 00:08:10.139
He's always thinking about industrial efficiency.

00:08:10.220 --> 00:08:13.529
He was, but his first solo patent. That was a

00:08:13.529 --> 00:08:15.870
real learning experience. It was. His very first

00:08:15.870 --> 00:08:18.769
patent, filed in 1869, was for an electric boat

00:08:18.769 --> 00:08:20.750
recorder. And the politicians, they completely

00:08:20.750 --> 00:08:23.790
ignored it. Didn't gain any adoption. They told

00:08:23.790 --> 00:08:26.610
him they preferred the long, complex process

00:08:26.610 --> 00:08:29.250
of voting because it allowed for last -minute

00:08:29.250 --> 00:08:31.610
deal -making and political maneuvering. What

00:08:31.610 --> 00:08:34.509
a lesson to learn. A vital one. It taught Edison

00:08:34.509 --> 00:08:37.710
that novelty for its own sake is worthless. You

00:08:37.710 --> 00:08:39.710
need utility. You need a market that actually

00:08:39.710 --> 00:08:42.009
wants what you're selling. He corrected course

00:08:42.009 --> 00:08:44.230
very quickly after that. Which brings us to the

00:08:44.230 --> 00:08:49.070
quadruplex telegraph in 1874. This was pure systems

00:08:49.070 --> 00:08:51.690
engineering applied to an industry with huge

00:08:51.690 --> 00:08:54.230
demand. It was revolutionary. Instead of one

00:08:54.230 --> 00:08:56.830
message, it could simultaneously transmit four

00:08:56.830 --> 00:08:59.870
messages through a single wire, two in each direction.

00:09:00.149 --> 00:09:03.210
So it quadrupled the capacity of the entire existing

00:09:03.210 --> 00:09:05.559
infrastructure overnight. Precisely. And the

00:09:05.559 --> 00:09:07.679
business value was immediately obvious to everyone.

00:09:07.759 --> 00:09:10.340
And the sale of that single invention, it literally

00:09:10.340 --> 00:09:13.320
funded his entire future. He sold the quadruplex

00:09:13.320 --> 00:09:16.559
for $30 ,000. Which, when you adjust for inflation,

00:09:16.779 --> 00:09:20.539
is over $833 ,000 in today's money. It wasn't

00:09:20.539 --> 00:09:23.340
just cash. It was the seed capital for the most

00:09:23.340 --> 00:09:25.779
important system he would ever create, the invention

00:09:25.779 --> 00:09:28.590
factory. OK, so with nearly a million dollars

00:09:28.590 --> 00:09:31.409
in today's money from that quadruplex sale, Edison

00:09:31.409 --> 00:09:34.610
builds Menlo Park in Raritan Township, New Jersey,

00:09:34.710 --> 00:09:38.049
in 1876. And we cannot overstate the importance

00:09:38.049 --> 00:09:40.350
of this. Menlo Park was not just a bigger basement

00:09:40.350 --> 00:09:42.289
workshop. The sources are definitive on this.

00:09:42.409 --> 00:09:44.669
It was the first industrial laboratory. What

00:09:44.669 --> 00:09:46.889
does that mean exactly? An industrial laboratory?

00:09:47.269 --> 00:09:49.289
It means it was concerned with creating knowledge

00:09:49.289 --> 00:09:52.159
and then crucially. controlling its application.

00:09:52.580 --> 00:09:55.200
This was the shift from the solitary inventor

00:09:55.200 --> 00:09:58.580
tinkering in a shed to an organized R &D team

00:09:58.580 --> 00:10:00.820
with a commercial goal. And the engine driving

00:10:00.820 --> 00:10:04.840
that team was Edison's infamous work ethic. Infamous

00:10:04.840 --> 00:10:07.539
is the right word. He worked extreme hours. We're

00:10:07.539 --> 00:10:10.720
talking 18 hours a day plus weekends. Yeah. And

00:10:10.720 --> 00:10:12.759
he drove his staff to what was famously described

00:10:12.759 --> 00:10:16.259
as the limits of human exhaustion. A brutal pace.

00:10:16.440 --> 00:10:18.830
Brutal. But it yielded this unparalleled volume

00:10:18.830 --> 00:10:22.169
of output, those 1 ,093 U .S. patents. They reflect

00:10:22.169 --> 00:10:24.990
this industrial systematic approach. And it's

00:10:24.990 --> 00:10:27.169
a key point that the credit for these inventions,

00:10:27.370 --> 00:10:30.070
while legally his as the director, was made possible

00:10:30.070 --> 00:10:32.409
by the engineers and chemists and machinists

00:10:32.409 --> 00:10:34.990
working tirelessly under him. He was the conductor

00:10:34.990 --> 00:10:37.070
of the orchestra. A very demanding conductor.

00:10:37.389 --> 00:10:39.549
And this structure meant he had to be incredibly

00:10:39.549 --> 00:10:41.309
aggressive about protecting his intellectual

00:10:41.309 --> 00:10:44.529
property. He had patent lawyers on staff and

00:10:44.529 --> 00:10:47.009
was constantly in court. Was he just defending

00:10:47.009 --> 00:10:49.570
his own ingenuity or was he defending the system

00:10:49.570 --> 00:10:52.250
he'd built? He was defending the system. He was

00:10:52.250 --> 00:10:55.289
defending the output of his employees. The moment

00:10:55.289 --> 00:10:57.409
the lab produced something marketable, he had

00:10:57.409 --> 00:11:00.190
to lock down the IP rights to maintain the business

00:11:00.190 --> 00:11:03.809
model. Litigation was just a necessary cost of

00:11:03.809 --> 00:11:05.409
doing business when you're churning out patents

00:11:05.409 --> 00:11:08.269
at that pace. To really get the mindset behind

00:11:08.269 --> 00:11:10.250
Menlo Park, you have to look at the physical

00:11:10.250 --> 00:11:13.700
space. The sources detail this unbelievable inventory

00:11:13.700 --> 00:11:16.480
he kept. He said he wanted the lab to have, quote,

00:11:16.600 --> 00:11:19.279
a stock of almost every conceivable material.

00:11:19.759 --> 00:11:22.200
It really was an omnivorous scientific horde.

00:11:22.279 --> 00:11:24.879
You find the things you'd expect, right? 8 ,000

00:11:24.879 --> 00:11:26.860
kinds of chemicals, every kind of screw ever

00:11:26.860 --> 00:11:28.940
made. And then it gets weird. And then you stumble

00:11:28.940 --> 00:11:31.960
into the bizarre and the organic. Hair of humans,

00:11:32.179 --> 00:11:35.779
horses, hogs, cows, camels, silk of every texture.

00:11:36.419 --> 00:11:39.559
Cocoa, hooves, shark's teeth, deer horns, tortoise

00:11:39.559 --> 00:11:42.500
shell. Wait, wait. Shark's teeth and camel hair.

00:11:42.659 --> 00:11:44.840
Why on earth did he need that kind of stuff just

00:11:44.840 --> 00:11:47.480
sitting on a shelf? It was central to his R &D

00:11:47.480 --> 00:11:50.120
process. You have to remember, this is before

00:11:50.120 --> 00:11:53.220
the internet, before global supply chains. When

00:11:53.220 --> 00:11:55.080
they were searching for the perfect material

00:11:55.080 --> 00:11:57.759
for a light bulb filament, or a better diaphragm

00:11:57.759 --> 00:12:00.240
for a microphone, they couldn't wait weeks to

00:12:00.240 --> 00:12:02.259
source something. They needed to test it now.

00:12:02.340 --> 00:12:05.080
Immediately. The lab had to be completely self

00:12:05.080 --> 00:12:07.850
-sufficient. That inventory, it was a physical

00:12:07.850 --> 00:12:10.789
manifestation of his relentless trial and error

00:12:10.789 --> 00:12:13.470
methodology. And he understood that if he branded

00:12:13.470 --> 00:12:16.110
this methodology, this hard work, he could shape

00:12:16.110 --> 00:12:19.129
how the public saw him. He was a master of publicity,

00:12:19.350 --> 00:12:21.629
and he often pushed back against being called

00:12:21.629 --> 00:12:24.529
a genius. He was extremely careful about that.

00:12:24.669 --> 00:12:26.610
He wanted to be seen as the tireless worker.

00:12:27.019 --> 00:12:28.879
That's where we get that famous line about invention

00:12:28.879 --> 00:12:32.419
being 1 % inspiration and 99 % perspiration.

00:12:32.460 --> 00:12:34.779
Why that framing? He was marketing effort over

00:12:34.779 --> 00:12:37.779
inherent brilliance. Because effort is repeatable

00:12:37.779 --> 00:12:40.919
and scalable. And most importantly, it's relatable

00:12:40.919 --> 00:12:44.019
to the common investor. And he didn't just control

00:12:44.019 --> 00:12:46.580
the public story. He tried to control the scientific

00:12:46.580 --> 00:12:50.100
story, too. This is fascinating. In 1880, he

00:12:50.100 --> 00:12:52.899
funded and anonymously served as the chief editor

00:12:52.899 --> 00:12:55.559
for Science Journal. The same highly respected

00:12:55.559 --> 00:12:57.799
publication we have today. So he was secretly

00:12:57.799 --> 00:13:01.120
running it. He was using it as a mouthpiece for

00:13:01.120 --> 00:13:03.379
articles that were favorable to his inventions

00:13:03.379 --> 00:13:05.940
and his research. When you connect this to the

00:13:05.940 --> 00:13:09.059
bigger picture, it shows this incredibly sophisticated

00:13:09.059 --> 00:13:12.559
modern understanding of narrative control. He

00:13:12.559 --> 00:13:14.960
wasn't just creating the science. He was controlling

00:13:14.960 --> 00:13:17.519
the authoritative platform that discussed the

00:13:17.519 --> 00:13:20.509
science. Let's look at a specific invention from

00:13:20.509 --> 00:13:22.830
this period that really illustrates this friction

00:13:22.830 --> 00:13:25.649
between Edison's claim and the collaborative

00:13:25.649 --> 00:13:28.730
nature of science. The carbon microphone. Right.

00:13:28.789 --> 00:13:31.929
So in 1876, he turns his attention to improving

00:13:31.929 --> 00:13:34.649
Alexander Graham Bell's telephone. What was the

00:13:34.649 --> 00:13:37.330
problem with Bell's phone? It was weak. It produced

00:13:37.330 --> 00:13:39.350
a current that was just too faint for any kind

00:13:39.350 --> 00:13:41.840
of long distance communication. Edison recognized

00:13:41.840 --> 00:13:43.740
the weakness was the microphone. It wasn't robust

00:13:43.740 --> 00:13:46.179
enough. So what was his solution? He realized

00:13:46.179 --> 00:13:48.840
he needed a material whose electrical resistance

00:13:48.840 --> 00:13:51.740
would vary a lot with just the small pressure

00:13:51.740 --> 00:13:54.899
changes from sound waves. He designed a carbon

00:13:54.899 --> 00:13:57.799
microphone, placing carbon granules between two

00:13:57.799 --> 00:14:00.600
metal plates. And when you spoke into it? The

00:14:00.600 --> 00:14:02.259
sound waves would change the pressure on the

00:14:02.259 --> 00:14:04.980
granules, which changed their resistance, and

00:14:04.980 --> 00:14:07.240
that created a much stronger varying current.

00:14:07.799 --> 00:14:10.799
He reportedly tested 150 materials before he

00:14:10.799 --> 00:14:13.679
landed on a special coated rubber diaphragm in

00:14:13.679 --> 00:14:16.360
carbon. And the result was a huge leap in telephone

00:14:16.360 --> 00:14:19.399
technology. An exponential leap. But, of course,

00:14:19.419 --> 00:14:22.610
controversy erupted almost immediately. A respected

00:14:22.610 --> 00:14:25.490
professor, David Edward Hughes, published a paper

00:14:25.490 --> 00:14:28.190
in 1878 on the physics of loose contact carbon

00:14:28.190 --> 00:14:30.830
microphones. And he claimed credit for discovering

00:14:30.830 --> 00:14:33.289
the underlying semiconductor effect that made

00:14:33.289 --> 00:14:35.909
it all work. So was Edison lying or was this

00:14:35.909 --> 00:14:37.509
just two people discovering the same thing at

00:14:37.509 --> 00:14:39.809
the same time? The sources suggest it was probably

00:14:39.809 --> 00:14:42.830
concurrent discovery. But Edison, aggressive

00:14:42.830 --> 00:14:45.470
as always, publicly challenged Hughes and fiercely

00:14:45.470 --> 00:14:47.870
defended his patent claim. He saw the invention

00:14:47.870 --> 00:14:50.639
as a functional commercial product. Hughes saw

00:14:50.639 --> 00:14:53.220
the underlying scientific principle. And Edison

00:14:53.220 --> 00:14:56.720
got the patent. He did. But the whole dispute

00:14:56.720 --> 00:15:00.240
highlights that ongoing tension. Was Edison a

00:15:00.240 --> 00:15:03.039
true inventor? Or was he simply the world's best

00:15:03.039 --> 00:15:05.320
industrial -scale appropriator of scientific

00:15:05.320 --> 00:15:08.059
principles discovered by himself or sometimes

00:15:08.059 --> 00:15:10.990
by others? It's clear his curiosity wasn't purely

00:15:10.990 --> 00:15:13.509
about what could be sold, though. Just two years

00:15:13.509 --> 00:15:16.629
later, in 1878, he invented something called

00:15:16.629 --> 00:15:19.210
the tessimeter. A completely non -commercial

00:15:19.210 --> 00:15:22.230
device. It was this highly sensitive little gadget

00:15:22.230 --> 00:15:25.009
designed to measure infrared radiation. And why

00:15:25.009 --> 00:15:27.129
did he build it? For a very specific reason.

00:15:27.850 --> 00:15:30.110
To gauge the heat coming from the solar corona,

00:15:30.570 --> 00:15:34.129
during the total solar eclipse on July 29, 1878.

00:15:34.350 --> 00:15:36.889
So he dedicated lab resources to pure science.

00:15:37.110 --> 00:15:39.570
Pure, unfettered scientific curiosity. It shows

00:15:39.570 --> 00:15:41.269
that even inside the pressure cooker of Menlo

00:15:41.269 --> 00:15:43.269
Park, he was still driven by these deep intellectual

00:15:43.269 --> 00:15:45.830
questions. Even if they had no immediate path

00:15:45.830 --> 00:15:48.529
to profit, it kind of humanizes the wizard before

00:15:48.529 --> 00:15:50.690
he becomes purely a business titan. While the

00:15:50.690 --> 00:15:52.870
test emitter was a curiosity, the phonograph

00:15:52.870 --> 00:15:55.789
in 1877 was the invention that made him a global

00:15:55.789 --> 00:15:58.289
sensation almost overnight. This is what earned

00:15:58.289 --> 00:16:00.690
him the title Wizard of Menlo Park. Because it

00:16:00.690 --> 00:16:03.490
really was perceived as magic. It was so novel.

00:16:04.029 --> 00:16:06.470
Other inventions could record sound waves visually,

00:16:06.690 --> 00:16:09.669
as a line on paper, but nothing could play them

00:16:09.669 --> 00:16:12.490
back. The ability to capture a human voice and

00:16:12.490 --> 00:16:15.009
then replay it. It was genuinely shocking to

00:16:15.009 --> 00:16:17.350
people. The famous scientist Joseph Henry declared

00:16:17.350 --> 00:16:19.929
him the most ingenious inventor in this country.

00:16:20.570 --> 00:16:23.639
Or in any other. His first model was pretty crude.

00:16:23.759 --> 00:16:26.059
It used a sheet of tinfoil wrapped around a grooved

00:16:26.059 --> 00:16:29.120
cylinder. Right. The quality was terrible, and

00:16:29.120 --> 00:16:31.179
a recording would only last for a few plays before

00:16:31.179 --> 00:16:34.139
the tinfoil was just destroyed. But the principle

00:16:34.139 --> 00:16:37.860
was proven. He patented it in 1878. And then

00:16:37.860 --> 00:16:40.580
in a pattern we see over and over, he just shelved

00:16:40.580 --> 00:16:43.019
it. He did. He was obsessed with electric light

00:16:43.019 --> 00:16:45.480
at the time, and the phonograph was left dormant

00:16:45.480 --> 00:16:48.139
for years, which was a huge mistake. Because

00:16:48.139 --> 00:16:49.980
it left the door wide open for his competitors.

00:16:50.100 --> 00:16:53.440
Exactly. Chisister Bell and Charles Tainter stepped

00:16:53.440 --> 00:16:56.240
in and produced a much better version using wax

00:16:56.240 --> 00:16:59.320
-coated cardboard cylinders in the 1880s. And

00:16:59.320 --> 00:17:01.120
that's what forced Edison to get back in the

00:17:01.120 --> 00:17:03.980
game. Hold on. If the invention was so revolutionary,

00:17:04.259 --> 00:17:07.019
why would he just stop working on it? Wouldn't

00:17:07.019 --> 00:17:10.259
a true entrepreneur rush to dominate the market?

00:17:10.559 --> 00:17:13.500
That's the paradox of Edison. He often focused

00:17:13.500 --> 00:17:16.579
on the breakthrough, on getting the patent. He'd

00:17:16.579 --> 00:17:18.559
assume that would establish his dominance, and

00:17:18.559 --> 00:17:20.970
then he'd move on to the next big problem. He

00:17:20.970 --> 00:17:23.589
sometimes missed that critical next phase of

00:17:23.589 --> 00:17:26.230
refinement and commercialization. Until a competitor

00:17:26.230 --> 00:17:29.990
forced his hand. Right. So in 1887, he founds

00:17:29.990 --> 00:17:32.309
the Edison Phonograph Company to compete with

00:17:32.309 --> 00:17:35.309
the superior wax cylinders. And this leads to

00:17:35.309 --> 00:17:37.849
these intense business battles, including the

00:17:37.849 --> 00:17:40.210
infamous Lippincott scheme. This is basically

00:17:40.210 --> 00:17:43.029
corporate espionage. Pure business espionage.

00:17:43.230 --> 00:17:45.750
A man named Jesse Lippincott tried to form a

00:17:45.750 --> 00:17:48.220
complete monopoly. He was offering deals to Edison,

00:17:48.400 --> 00:17:50.920
to his longtime friend Ezra Gilliland, and to

00:17:50.920 --> 00:17:53.319
the Bell interests, all while deliberately hiding

00:17:53.319 --> 00:17:55.660
his real goal. Which was to control all the patents.

00:17:55.799 --> 00:17:58.559
Exactly. Edison was completely blindsided when

00:17:58.559 --> 00:18:00.259
he figured it out. And the revelation, it cost

00:18:00.259 --> 00:18:02.460
him a really important friendship. It did. His

00:18:02.460 --> 00:18:04.559
25 -year friendship with Gilliland was immediately

00:18:04.559 --> 00:18:07.779
over. It led to five agonizing years of litigation

00:18:07.779 --> 00:18:11.519
until Edison finally managed to take total control

00:18:11.519 --> 00:18:14.160
of the company and the patents. The cost of that

00:18:14.160 --> 00:18:17.119
victory was enormous. both personally and financially.

00:18:17.339 --> 00:18:19.279
We also have to talk about the comical failures

00:18:19.279 --> 00:18:22.759
from this phase. The talking dolls. A famous

00:18:22.759 --> 00:18:25.799
industrial misstep. He tried to mass produce

00:18:25.799 --> 00:18:28.180
these talking dolls with tiny phonographs inside,

00:18:28.480 --> 00:18:30.619
hoping to capture the toy market. And they were

00:18:30.619 --> 00:18:33.440
not great. They were so fragile that the mechanism

00:18:33.440 --> 00:18:35.980
usually failed during shipment. And sometimes

00:18:35.980 --> 00:18:38.160
they would arrive with these horrifying, distorted...

00:18:38.329 --> 00:18:40.890
demonic sounding voices. Production was shut

00:18:40.890 --> 00:18:44.170
down in 1890, a very public and very embarrassing

00:18:44.170 --> 00:18:46.349
failure. What's really insightful about the phonograph,

00:18:46.529 --> 00:18:49.089
though, is that Edison completely misjudged its

00:18:49.089 --> 00:18:50.970
commercial potential at first. He saw it as a

00:18:50.970 --> 00:18:53.730
business tool. Right. A tool for dictation, something

00:18:53.730 --> 00:18:56.829
to redefine the role of secretaries. He saw efficiency.

00:18:57.150 --> 00:18:59.130
And the market saw entertainment. The market

00:18:59.130 --> 00:19:02.809
wanted music. And by 1899, Edison finally gave

00:19:02.809 --> 00:19:05.630
in to market demands. He produced a cheap model

00:19:05.630 --> 00:19:08.460
just for entertainment. It sold for $10 by 1900,

00:19:08.720 --> 00:19:11.400
and he had a catalog of 3 ,000 musical records.

00:19:12.220 --> 00:19:14.700
This pivot shows that even the great systemizer

00:19:14.700 --> 00:19:16.900
couldn't just dictate what consumers wanted.

00:19:17.079 --> 00:19:18.740
And this brings us right back to that central

00:19:18.740 --> 00:19:21.259
paradox we started with. Edison was mostly deaf,

00:19:21.460 --> 00:19:23.519
he had no musical training, he couldn't read

00:19:23.519 --> 00:19:26.559
sheet music, and yet he exerted this tight personal

00:19:26.559 --> 00:19:29.539
control over the early music industry. It's incredible.

00:19:29.900 --> 00:19:32.059
The sources show that all the way through 1915,

00:19:32.339 --> 00:19:35.680
he personally approved every single artist and

00:19:35.680 --> 00:19:38.240
every single musical record released by his company.

00:19:38.400 --> 00:19:40.480
On what basis? On the basis of what he thought

00:19:40.480 --> 00:19:43.099
sounded good, physically to him. He was essentially

00:19:43.099 --> 00:19:46.339
judging complex auditory art through skeletal

00:19:46.339 --> 00:19:48.859
vibration and raw tonal quality. And he didn't

00:19:48.859 --> 00:19:50.759
even want the artists' names on the records?

00:19:50.960 --> 00:19:53.359
No. He saw the records purely as outputs of the

00:19:53.359 --> 00:19:55.799
Edison system, not as artistic expressions by

00:19:55.799 --> 00:19:57.579
individuals. It's hard to grasp the profound

00:19:57.579 --> 00:20:00.170
irony there. The man controlling the soundscape

00:20:00.170 --> 00:20:02.589
of the modern world experienced that art in a

00:20:02.589 --> 00:20:05.490
fundamentally diminished physical way. It's a

00:20:05.490 --> 00:20:07.789
powerful illustration of how unique limitation

00:20:07.789 --> 00:20:12.190
can drive a creator to hyper focus on the technical

00:20:12.190 --> 00:20:14.569
quality and the reproduction of an experience

00:20:14.569 --> 00:20:17.430
they can't fully have themselves. That controlling,

00:20:17.470 --> 00:20:19.890
resistant nature, though, it ultimately proved

00:20:19.890 --> 00:20:22.009
to be a huge liability when the next revolution

00:20:22.009 --> 00:20:25.329
arrived. Radio. Absolutely. The widespread adoption

00:20:25.329 --> 00:20:28.750
of radio just. Dissimated phonograph sales. The

00:20:28.750 --> 00:20:31.470
numbers are shocking. Edison's record sales dropped

00:20:31.470 --> 00:20:36.609
90 % between 1920 and 1921. A 90 % drop. Meanwhile,

00:20:36.849 --> 00:20:42.490
radio sales surged 843 % from 1922 to 1926. And

00:20:42.490 --> 00:20:44.690
despite desperate pleas from his younger managers,

00:20:45.049 --> 00:20:47.990
even from his own son Charles, Edison just refused

00:20:47.990 --> 00:20:50.130
to get into the radio business. He was stubborn.

00:20:50.490 --> 00:20:52.710
He was focused on micromanaging internal staff

00:20:52.710 --> 00:20:55.410
issues. Instead of acknowledging this massive

00:20:55.410 --> 00:20:57.130
technological shift that was happening right

00:20:57.130 --> 00:20:59.109
in front of him, it suggests that his greatest

00:20:59.109 --> 00:21:01.829
strength total system control became his greatest

00:21:01.829 --> 00:21:04.230
weakness when he was faced with true disruption.

00:21:04.490 --> 00:21:07.190
If the phonograph made him famous, the system

00:21:07.190 --> 00:21:09.349
of electric light made him a foundational figure

00:21:09.349 --> 00:21:13.490
in history. By 1878, his goal was not just to

00:21:13.490 --> 00:21:16.160
invent a light bulb. No, that's the crucial distinction.

00:21:16.420 --> 00:21:19.359
He wanted to invent an entire system of illumination

00:21:19.359 --> 00:21:21.700
that could compete directly with the existing

00:21:21.700 --> 00:21:24.480
gas and oil lighting infrastructure. He understood

00:21:24.480 --> 00:21:26.759
that a successful invention needed the whole

00:21:26.759 --> 00:21:29.400
support system to be commercially viable as a

00:21:29.400 --> 00:21:32.680
utility. Generation, transmission, metering,

00:21:32.900 --> 00:21:35.960
safety. The light bulb was just one component

00:21:35.960 --> 00:21:38.259
of a much bigger puzzle. But it was a critical

00:21:38.259 --> 00:21:40.660
component. Other bulbs existed, but they died

00:21:40.660 --> 00:21:43.619
quickly and used way too much power. His immediate

00:21:43.619 --> 00:21:46.880
goal was a durable, low -resistance, incandescent

00:21:46.880 --> 00:21:49.700
lamp. What was the process for finding that perfect

00:21:49.700 --> 00:21:52.640
filament? It was a brutal, methodical slog of

00:21:52.640 --> 00:21:55.700
trial and error. Just pure perspiration. He started

00:21:55.700 --> 00:21:57.599
with carbonized cardboard, which burned out almost

00:21:57.599 --> 00:22:00.200
instantly. Then he moved through thousands of

00:22:00.200 --> 00:22:03.000
organic materials. Like what? Linen thread, hemp,

00:22:03.240 --> 00:22:05.720
palmetto fiber. He was systematically sending

00:22:05.720 --> 00:22:07.759
people out to the world to find materials with

00:22:07.759 --> 00:22:09.839
the right kind of cellular structure to hold

00:22:09.839 --> 00:22:11.859
up under the heat. And what was the breakthrough

00:22:11.859 --> 00:22:15.309
material? Carbonized bamboo. The sources note

00:22:15.309 --> 00:22:17.930
that a single thin strand of carbonized bamboo

00:22:17.930 --> 00:22:22.009
fiber could last for over 1 ,200 hours. And the

00:22:22.009 --> 00:22:24.349
key property of that bamboo was its high resistance.

00:22:24.869 --> 00:22:27.430
Exactly. And that high resistance was the critical

00:22:27.430 --> 00:22:30.150
factor that dictated the choice of his power

00:22:30.150 --> 00:22:34.349
source, 110 volts direct current, or DC. Why

00:22:34.349 --> 00:22:36.930
that specific voltage? Because the high voltage

00:22:36.930 --> 00:22:38.750
meant you needed less current to get the same

00:22:38.750 --> 00:22:40.799
amount of power. which in turn meant you could

00:22:40.799 --> 00:22:44.099
use thinner and much, much cheaper copper wiring.

00:22:44.319 --> 00:22:46.519
So the choice of filament dictated the entire

00:22:46.519 --> 00:22:48.799
standard for the U .S. power grid that we still

00:22:48.799 --> 00:22:51.099
use today. That's an amazing chain reaction.

00:22:51.420 --> 00:22:53.440
It speaks volumes about his system thinking.

00:22:53.819 --> 00:22:57.039
And to manage this huge effort, he built a stellar

00:22:57.039 --> 00:23:00.460
team. He hired Francis Robbins Upton, a brilliant

00:23:00.460 --> 00:23:02.279
mathematician who had studied under the great

00:23:02.279 --> 00:23:04.420
Hermann von Helmholtz. Upton was the general

00:23:04.420 --> 00:23:06.980
manager. Right. And he was compensated handsomely

00:23:06.980 --> 00:23:09.700
for it with 5 % of the profits. That kind of

00:23:09.700 --> 00:23:11.859
compensation structure must have motivated some

00:23:11.859 --> 00:23:15.019
exceptional loyalty and effort. Absolutely. The

00:23:15.019 --> 00:23:18.200
systematic, organized, compensated R &D model

00:23:18.200 --> 00:23:21.039
was in full effect. And you had his experimental

00:23:21.039 --> 00:23:23.819
assistants, the brothers John and Fred Ott, who

00:23:23.819 --> 00:23:27.140
were indispensable. They did the grueling, repetitive

00:23:27.140 --> 00:23:29.819
experiment, perfecting the vacuum inside the

00:23:29.819 --> 00:23:32.359
bulb and the intricate glasswork required to

00:23:32.359 --> 00:23:34.500
make them durable. The viability of the whole

00:23:34.500 --> 00:23:37.000
system was proven commercially in 1880. Yes,

00:23:37.099 --> 00:23:39.559
on the steamship Columbia, which was owned by

00:23:39.559 --> 00:23:42.099
Henry Villard. It was the first commercial vessel

00:23:42.099 --> 00:23:44.500
to have Edison's lighting system installed. And

00:23:44.500 --> 00:23:46.660
Villard was so impressed he became a major investor.

00:23:46.980 --> 00:23:49.559
He did. He became one of Edison's key financiers

00:23:49.559 --> 00:23:51.980
moving forward. And building on that success,

00:23:52.220 --> 00:23:54.599
Edison founded the Edison Electric Light Company

00:23:54.599 --> 00:23:57.670
in 1880. attracting huge names like JP Morgan

00:23:57.670 --> 00:23:59.990
and the Vanderbilts. Now, to commercialize this,

00:24:00.130 --> 00:24:02.450
they had to solve the massive problem of getting

00:24:02.450 --> 00:24:04.930
power from the generator to the customer without

00:24:04.930 --> 00:24:07.829
going bankrupt on the cost of copper wire. Because

00:24:07.829 --> 00:24:11.089
DC requires really thick copper wires for safe,

00:24:11.130 --> 00:24:14.509
low voltage transmission. His solution was the

00:24:14.509 --> 00:24:17.250
three prong wire system, which dramatically reduced

00:24:17.250 --> 00:24:19.289
the amount of copper needed and made the whole

00:24:19.289 --> 00:24:21.569
infrastructure financially feasible. And then

00:24:21.569 --> 00:24:23.509
there's the logistical challenge of metering.

00:24:23.950 --> 00:24:26.269
How did he build people without the modern meters

00:24:26.269 --> 00:24:29.109
we have today? He invented this brilliant chemical

00:24:29.109 --> 00:24:32.190
-based metering solution. It was a little cell

00:24:32.190 --> 00:24:34.769
that contained a zinc solution and two zinc plates.

00:24:35.410 --> 00:24:38.289
This device was installed in every customer's

00:24:38.289 --> 00:24:41.470
home. How did it work? A fixed percentage of

00:24:41.470 --> 00:24:44.269
the current the customer used would flow through

00:24:44.269 --> 00:24:46.509
this cell, and that current would cause zinc

00:24:46.509 --> 00:24:49.190
to precipitate or deposit onto one of the plates.

00:24:49.269 --> 00:24:50.849
So he wasn't measuring the electricity directly.

00:24:50.890 --> 00:24:53.109
He was measuring the chemical output of the electricity?

00:24:53.390 --> 00:24:55.349
Precisely. The plates were collected in weight

00:24:55.349 --> 00:24:57.950
every month. The difference in weight told them

00:24:57.950 --> 00:25:00.150
exactly how much power the customer had used,

00:25:00.289 --> 00:25:02.670
and that's how they calculated the bill. It was

00:25:02.670 --> 00:25:05.670
a literal cash register in a jar. It just shows

00:25:05.670 --> 00:25:08.190
how Edison was always leveraging chemistry to

00:25:08.190 --> 00:25:10.230
solve electrical engineering problems. And the

00:25:10.230 --> 00:25:12.490
whole system officially launched on September

00:25:12.490 --> 00:25:16.190
4, 1882, with the 600 -kilowatt Pearl Street

00:25:16.190 --> 00:25:19.150
Station in New York City providing 110 volts

00:25:19.150 --> 00:25:22.309
of DC power. And the success was so subtle, it

00:25:22.309 --> 00:25:24.849
was revolutionary. The Boston Globe had this

00:25:24.849 --> 00:25:27.109
great line about it. They noted that very few

00:25:27.109 --> 00:25:29.849
people even noticed the switch from gas because

00:25:29.849 --> 00:25:32.009
the electric lights were so steady and so similar.

00:25:32.329 --> 00:25:35.640
They wrote, Edison has had an opening night.

00:25:36.109 --> 00:25:39.230
His aim is to open night until it shall be his

00:25:39.230 --> 00:25:42.210
day. It was so seamless, people barely realized

00:25:42.210 --> 00:25:44.869
this fundamental technological shift had just

00:25:44.869 --> 00:25:47.470
occurred right under their noses. A quiet revolution.

00:25:47.829 --> 00:25:50.509
But the empire had a built -in weakness, a real

00:25:50.509 --> 00:25:53.230
Achilles heel that the DC system just could not

00:25:53.230 --> 00:25:56.190
overcome. Distance. Distance. That's right. Because

00:25:56.190 --> 00:25:59.109
of the inherent voltage drop, DC power plants

00:25:59.109 --> 00:26:01.990
could not reliably deliver electricity more than

00:26:01.990 --> 00:26:05.230
about 1 .6 kilometers from the source. Which

00:26:05.230 --> 00:26:07.819
meant... the DC system was fantastic for dense

00:26:07.819 --> 00:26:10.200
urban areas like Manhattan. Completely untutable

00:26:10.200 --> 00:26:13.000
for small cities, towns, or any rural areas.

00:26:13.180 --> 00:26:15.799
And this limitation provided the perfect entry

00:26:15.799 --> 00:26:17.640
point for George Westinghouse and alternating

00:26:17.640 --> 00:26:20.670
current, or AC. And this ushers in the infamous

00:26:20.670 --> 00:26:23.549
war of the currents. AC had the transformative

00:26:23.549 --> 00:26:25.990
element of the transformer. It could step voltages

00:26:25.990 --> 00:26:28.809
up and down easily. This meant AC could be transmitted

00:26:28.809 --> 00:26:31.289
for long distances at very high voltage over

00:26:31.289 --> 00:26:33.750
cheaper, thinner wires and then be stepped down

00:26:33.750 --> 00:26:36.190
safely for people to use in their homes. So AC

00:26:36.190 --> 00:26:38.690
immediately started gaining massive market share

00:26:38.690 --> 00:26:41.589
by servicing all the territories that DC just

00:26:41.589 --> 00:26:43.609
couldn't touch. And Edison's reaction to this

00:26:43.609 --> 00:26:46.309
competition was not innovative. It was dogmatic.

00:26:46.309 --> 00:26:48.859
It was intensely personal. And frankly, It was

00:26:48.859 --> 00:26:51.500
ugly. An all -out propaganda war. Completely.

00:26:51.700 --> 00:26:54.279
He struck out personally against George Westinghouse,

00:26:54.440 --> 00:26:56.819
publicly stating, and this is a quote, just as

00:26:56.819 --> 00:26:59.200
certain as death, Westinghouse will kill a customer

00:26:59.200 --> 00:27:01.480
within six months after he puts in a system of

00:27:01.480 --> 00:27:04.589
any size. He was leveraging public fear against

00:27:04.589 --> 00:27:06.670
the dangers of high voltage transmission. Was

00:27:06.670 --> 00:27:09.609
this really about safety or was it about protecting

00:27:09.609 --> 00:27:11.829
his huge investment in D .C. infrastructure?

00:27:12.349 --> 00:27:14.450
Oh, it was overwhelmingly about business and

00:27:14.450 --> 00:27:17.109
sunk costs. Edison Electric had installed over

00:27:17.109 --> 00:27:20.190
100 D .C. systems. The idea of switching the

00:27:20.190 --> 00:27:22.509
standard of invalidating millions of dollars

00:27:22.509 --> 00:27:24.690
in infrastructure was financially impossible

00:27:24.690 --> 00:27:28.369
for him. And by 1887, he was losing ground fast.

00:27:29.369 --> 00:27:33.230
Rapidly. You had 121 D .C. stations versus Westinghouse's

00:27:33.230 --> 00:27:35.950
68 A .C. and another rival, Thompson Houston,

00:27:36.150 --> 00:27:38.569
with 22. He was fighting for his corporate life.

00:27:38.730 --> 00:27:40.890
And this fight led to one of the darker episodes

00:27:40.890 --> 00:27:44.289
in his history, the electrocution campaign. Edison

00:27:44.289 --> 00:27:46.769
joins forces with a man named Harold P. Brown

00:27:46.769 --> 00:27:50.769
to publicly discredit A .C. They publicly electrocuted

00:27:50.769 --> 00:27:53.789
animals, dogs, horses, and most famously, Topsy

00:27:53.789 --> 00:27:56.829
the Elephant. They used high -voltage A .C. to

00:27:56.829 --> 00:27:59.400
demonstrate its lethality. It was pure spectacle.

00:27:59.660 --> 00:28:01.779
It was theatricality designed to associate AC

00:28:01.779 --> 00:28:04.740
power with instant terrifying death in the public's

00:28:04.740 --> 00:28:07.220
mind. And they lobbied aggressively for legislation

00:28:07.220 --> 00:28:09.779
to severely limit AC voltages, hoping to just

00:28:09.779 --> 00:28:11.859
make it commercially unviable. And this campaign

00:28:11.859 --> 00:28:13.720
culminates with the invention of the electric

00:28:13.720 --> 00:28:17.009
chair. Yes. Edison actively colluded with Westinghouse's

00:28:17.009 --> 00:28:19.190
main rival, Thompson Houston, to make sure the

00:28:19.190 --> 00:28:20.910
first electric chair was designed to be powered

00:28:20.910 --> 00:28:23.509
by a Westinghouse AC generator. The goal was

00:28:23.509 --> 00:28:26.529
to permanently brand AC as the executioner's

00:28:26.529 --> 00:28:30.069
current. A utility of death. And the irony, of

00:28:30.069 --> 00:28:32.990
course, is that Edison, the committed pacifist,

00:28:33.029 --> 00:28:36.029
was engineering a machine designed to kill people,

00:28:36.130 --> 00:28:39.470
all in the name of a business dispute. Despite

00:28:39.470 --> 00:28:42.269
all the drama and the terrible PR campaign, the

00:28:42.269 --> 00:28:45.849
economics were just undeniable. And by 1892,

00:28:46.269 --> 00:28:48.430
JP Morgan, seeing the financial instability,

00:28:48.809 --> 00:28:51.609
he had to intervene. Morgan engineered a forced

00:28:51.609 --> 00:28:53.990
merger of Edison General Electric with their

00:28:53.990 --> 00:28:57.029
rival, Thompson Houston. The scale of the financial

00:28:57.029 --> 00:28:59.089
engineering here was immense. And this was the

00:28:59.089 --> 00:29:01.619
ultimate corporate defeat for Edison. Morgan

00:29:01.619 --> 00:29:03.559
decided that Thompson Houston was actually the

00:29:03.559 --> 00:29:06.099
more valuable company. He did. He ousted Edison's

00:29:06.099 --> 00:29:08.480
allies. He put the rival board in charge and

00:29:08.480 --> 00:29:11.279
he renamed the entire operation General Electric

00:29:11.279 --> 00:29:14.539
GE. A hostile takeover hidden inside a merger.

00:29:14.839 --> 00:29:17.400
Absolutely. Edison was publicly supportive, you

00:29:17.400 --> 00:29:19.460
know, put on a brave face. But privately, he

00:29:19.460 --> 00:29:21.880
was incredibly bitter that his namesake company

00:29:21.880 --> 00:29:23.559
and all the patents he had systematically developed

00:29:23.559 --> 00:29:25.519
were just turned over to the competition he had

00:29:25.519 --> 00:29:27.900
thought so hard to destroy. He served as a figurehead

00:29:27.900 --> 00:29:29.779
for a while and then he just sold his shares.

00:29:30.220 --> 00:29:32.400
And this raises a really important question for

00:29:32.400 --> 00:29:34.700
you, the learner. After the founding inventor

00:29:34.700 --> 00:29:37.599
establishes the system, how much do they really

00:29:37.599 --> 00:29:40.559
matter? Edison was the catalyst, but the merger

00:29:40.559 --> 00:29:43.059
proves that once a technology reaches that massive

00:29:43.059 --> 00:29:45.960
commercial scale, financial engineering and distribution

00:29:45.960 --> 00:29:48.500
strategy often become more important than the

00:29:48.500 --> 00:29:52.279
original creator. So after basically losing control

00:29:52.279 --> 00:29:54.759
of the electrical industry he created, Edison

00:29:54.759 --> 00:29:57.990
didn't retire. He pivoted entirely. He poured

00:29:57.990 --> 00:29:59.730
his energy into what sounds like a completely

00:29:59.730 --> 00:30:02.809
unrelated, massive endeavor, mining. Right. From

00:30:02.809 --> 00:30:06.130
the late 1870s all the way to 1903. And he was

00:30:06.130 --> 00:30:08.769
driven by another commercial necessity. High

00:30:08.769 --> 00:30:11.130
-grade iron ore was scarce and very expensive

00:30:11.130 --> 00:30:13.690
on the East Coast. So Edison decides he can profitably

00:30:13.690 --> 00:30:16.789
mine low -grade ore and even beach sand using

00:30:16.789 --> 00:30:19.289
his specialty. Magnetics and industrial automation.

00:30:19.609 --> 00:30:21.910
He threw a tremendous amount of capital and technology

00:30:21.910 --> 00:30:24.150
at this idea. He bought several mines and built

00:30:24.150 --> 00:30:27.130
this huge new automated operation in Ogdensburg,

00:30:27.250 --> 00:30:29.490
New Jersey. This wasn't a small lab experiment.

00:30:29.630 --> 00:30:32.700
This was heavy industry. It was colossal. He

00:30:32.700 --> 00:30:34.799
purchased the largest steam shovel in America

00:30:34.799 --> 00:30:37.220
at the time. His whole system relied on these

00:30:37.220 --> 00:30:40.319
electrically powered 70 -ton rollers to crush

00:30:40.319 --> 00:30:43.099
5 -ton rocks. He was obsessed with automation.

00:30:43.460 --> 00:30:46.190
He wanted the system to work so that And this

00:30:46.190 --> 00:30:49.730
is a quote, no humans would touch the iron until

00:30:49.730 --> 00:30:52.609
it was fully processed. That vision of full automation

00:30:52.609 --> 00:30:54.769
in the late 19th century is just incredible.

00:30:55.029 --> 00:30:57.470
So how did the magnetic separation part work?

00:30:57.609 --> 00:30:59.910
Once the rocks were crushed down into fines like

00:30:59.910 --> 00:31:02.670
a coarse sand, the material would pass through

00:31:02.670 --> 00:31:05.750
this array of 480 powerful electromagnets. And

00:31:05.750 --> 00:31:07.509
they would just pull the iron out. They'd select

00:31:07.509 --> 00:31:09.549
the minuscule iron content from all the waste

00:31:09.549 --> 00:31:12.170
rock. He even added a pneumatic system, a big

00:31:12.170 --> 00:31:14.430
blast of air to remove phosphorus, which was

00:31:14.430 --> 00:31:17.089
unacceptable. in the steelmaking process. He

00:31:17.089 --> 00:31:18.809
was leveraging the slight density difference

00:31:18.809 --> 00:31:21.490
between the iron fines and the phosphorus compounds.

00:31:21.869 --> 00:31:24.849
So he applied the systematic scientific R &D

00:31:24.849 --> 00:31:27.410
model of Menlo Park to a giant pile of dirt.

00:31:27.549 --> 00:31:29.390
Everything was automated, measured, optimized.

00:31:29.869 --> 00:31:32.269
Did it work? Technologically, yes, it worked.

00:31:32.390 --> 00:31:34.430
Financially, it was a catastrophic failure. What

00:31:34.430 --> 00:31:36.849
happened? A severe economic recession hit in

00:31:36.849 --> 00:31:40.529
1893. Iron prices just fell through the floor,

00:31:40.650 --> 00:31:42.869
and that instantly rendered his high capital

00:31:42.869 --> 00:31:46.240
investment worthless. Despite all the advanced

00:31:46.240 --> 00:31:48.359
technology, the mine was just bleeding money

00:31:48.359 --> 00:31:51.380
and it put Edison near insolvency. He failed

00:31:51.380 --> 00:31:54.359
so spectacularly that he had to take a loan from

00:31:54.359 --> 00:31:57.079
his father -in -law just to stay afloat. He did.

00:31:57.240 --> 00:32:00.099
And it took him until 1903 to finally give up

00:32:00.099 --> 00:32:02.519
on the whole thing. It must have been devastating.

00:32:02.720 --> 00:32:06.000
A total industrial scale defeat. But here's where

00:32:06.000 --> 00:32:08.700
Edison's pragmatism is just so impressive. He

00:32:08.700 --> 00:32:10.460
didn't just walk away from all that infrastructure

00:32:10.460 --> 00:32:12.819
and the thousands of tons of waste sand. No,

00:32:12.819 --> 00:32:15.519
he pivoted immediately. To cement production.

00:32:15.900 --> 00:32:18.859
So the mining failure became the literal foundation

00:32:18.859 --> 00:32:21.640
for his next big success. Precisely. He used

00:32:21.640 --> 00:32:23.680
the waste sand and all the surviving massive

00:32:23.680 --> 00:32:25.940
equipment from the failed Augensburg venture

00:32:25.940 --> 00:32:28.680
to produce Portland cement. He established the

00:32:28.680 --> 00:32:31.359
Edison Portland Cement Company in 1899. What

00:32:31.359 --> 00:32:33.319
was his innovation in cement? Surely he wasn't

00:32:33.319 --> 00:32:35.880
the first person to make it. No, but he innovated

00:32:35.880 --> 00:32:39.380
the process. He designed these novel, horizontal...

00:32:39.609 --> 00:32:43.109
150 -foot -long kilns. Traditional kilns were

00:32:43.109 --> 00:32:45.569
smaller and required hotter, faster heat. And

00:32:45.569 --> 00:32:48.369
his were longer and cooler. Exactly. Edison's

00:32:48.369 --> 00:32:50.470
longer kilns allowed the cement to cook for a

00:32:50.470 --> 00:32:53.230
longer time at a lower temperature, which consumed

00:32:53.230 --> 00:32:55.890
significantly less coal and required less labor.

00:32:56.029 --> 00:32:58.670
It was a massive efficiency game. It sounds like

00:32:58.670 --> 00:33:00.769
he leveraged the mining experience to become

00:33:00.769 --> 00:33:03.549
an industrial engineer specializing in material

00:33:03.549 --> 00:33:06.130
processing. That's a great way to put it. And

00:33:06.130 --> 00:33:08.869
he licensed this proven efficient system to other

00:33:08.869 --> 00:33:11.230
manufacturers. He was collecting royalties on

00:33:11.230 --> 00:33:13.930
it well into the 1920s. This turned out to be

00:33:13.930 --> 00:33:16.230
one of his most profitable and stable long -term

00:33:16.230 --> 00:33:18.390
ventures. And he even tried to solve the housing

00:33:18.390 --> 00:33:20.910
crisis with cement, didn't he? He did. He wanted

00:33:20.910 --> 00:33:23.430
to parlay the cement business into cheap, durable

00:33:23.430 --> 00:33:25.809
housing. He commissioned a system for casting

00:33:25.809 --> 00:33:28.609
an entire three -story house. from cement in

00:33:28.609 --> 00:33:31.869
a single mold. A single pore? One single pore.

00:33:32.269 --> 00:33:35.670
It was intended for employee housing, a revolutionary

00:33:35.670 --> 00:33:39.130
concept. But the complexity and, well, the lack

00:33:39.130 --> 00:33:41.670
of public demand for these monolithic gray homes

00:33:41.670 --> 00:33:43.890
meant it never really took off commercially.

00:33:44.230 --> 00:33:46.630
Moving into the 20th century, the sources show

00:33:46.630 --> 00:33:49.250
Edison dedicating his systematic approach to

00:33:49.250 --> 00:33:51.730
national security during World War I. At the

00:33:51.730 --> 00:33:53.569
start of the war, the U .S. chemical industry

00:33:53.569 --> 00:33:56.319
was pretty primitive. It relied heavily on European

00:33:56.319 --> 00:33:59.220
imports, especially from Germany, for critical

00:33:59.220 --> 00:34:02.359
materials like phenol. Phenol being the key ingredient

00:34:02.359 --> 00:34:05.359
for explosives and for aspirin. So when the war

00:34:05.359 --> 00:34:07.660
started, there was an immediate critical shortage.

00:34:08.000 --> 00:34:11.199
Edison responded with astonishing speed. He undertook

00:34:11.199 --> 00:34:13.840
production at his Silver Lake facility. He built

00:34:13.840 --> 00:34:15.900
two plants with a capacity of six tons a day,

00:34:16.019 --> 00:34:18.519
just one month after hostilities began in Europe.

00:34:18.679 --> 00:34:21.360
He applied the R &D process to... chemistry,

00:34:21.519 --> 00:34:25.840
manufacturing benzene, aniline dyes, xylene shellac.

00:34:26.019 --> 00:34:28.320
The wartime shortages made these ventures incredibly

00:34:28.320 --> 00:34:30.659
profitable and it fueled his company through

00:34:30.659 --> 00:34:33.340
the war years. But there's a fascinating moral

00:34:33.340 --> 00:34:36.380
wrinkle here about his pacifism. Right. He preferred

00:34:36.380 --> 00:34:39.260
not to sell his phenol for military uses. So

00:34:39.260 --> 00:34:42.079
he ended up selling the surplus to Bayer, who

00:34:42.079 --> 00:34:45.099
then exported it to Germany. So he was technically

00:34:45.099 --> 00:34:48.099
aiding the enemy. While holding true to his moral

00:34:48.099 --> 00:34:50.679
commitment not to invent or manufacture weapons.

00:34:50.880 --> 00:34:54.300
It's a contradiction. But at the same time, he

00:34:54.300 --> 00:34:56.860
was ensuring U .S. industrial self -sufficiency,

00:34:57.039 --> 00:34:59.739
which was his main goal. His dedication to self

00:34:59.739 --> 00:35:01.940
-sufficiency continued with the rubber project.

00:35:02.119 --> 00:35:05.360
After the Stevenson Plan in 1921 created these

00:35:05.360 --> 00:35:07.420
national security concerns about the rubber supply,

00:35:07.820 --> 00:35:10.880
Edison, Henry Ford, and Harvey Firestone jointly

00:35:10.880 --> 00:35:13.800
funded a massive research effort. They contributed

00:35:13.800 --> 00:35:16.920
$75 ,000 to systematically find a domestic source

00:35:16.920 --> 00:35:19.519
of rubber. And the task was just massive. His

00:35:19.519 --> 00:35:22.599
teams tested an unbelievable 17 ,000 different

00:35:22.599 --> 00:35:25.460
plant samples. 17 ,000? How do you even manage

00:35:25.460 --> 00:35:27.780
a project like that? With an aggressive, systematic

00:35:27.780 --> 00:35:31.420
filtration process based on six criteria. Latex

00:35:31.420 --> 00:35:33.780
content, ease of extraction, where the latex

00:35:33.780 --> 00:35:35.599
was in the plant, growth speed, harvestability,

00:35:35.840 --> 00:35:37.500
and sustainability. And what was the conclusion?

00:35:37.820 --> 00:35:39.920
They found an adequate source in the Goldenrod

00:35:39.920 --> 00:35:43.230
plant. Specifically, a species called Solidago

00:35:43.230 --> 00:35:46.110
leavenworthy eye. And through systematic breeding,

00:35:46.309 --> 00:35:48.630
they managed to increase the plant's latex yield

00:35:48.630 --> 00:35:52.309
to a commercially viable 12%. It was a fitting

00:35:52.309 --> 00:35:55.210
late -career triumph for him. Solving a huge

00:35:55.210 --> 00:35:57.550
national problem with nothing but relentless,

00:35:57.690 --> 00:36:00.389
organized research. Proving the enduring value

00:36:00.389 --> 00:36:03.329
of the Menlo Park model, decades later. Let's

00:36:03.329 --> 00:36:05.110
transition to his work in visual technology.

00:36:05.710 --> 00:36:08.230
Edison had a very clear goal for motion pictures.

00:36:08.590 --> 00:36:11.710
He wanted, in his words, to do for the eye what

00:36:11.710 --> 00:36:13.829
the phonograph does for the ear. He envisioned

00:36:13.829 --> 00:36:16.989
a kinetophonograph. Perfectly synchronized sound

00:36:16.989 --> 00:36:19.909
and video. The problem was achieving that synchronization.

00:36:20.250 --> 00:36:23.050
It was incredibly difficult. Edison focused on

00:36:23.050 --> 00:36:25.329
the electromechanical parts, the driving mechanisms,

00:36:25.570 --> 00:36:27.710
the shutters. But a lot of the credit for the

00:36:27.710 --> 00:36:30.489
optical and film efforts really goes to his employee.

00:36:30.940 --> 00:36:32.860
William Kennedy Dixon. Dixon was the one who

00:36:32.860 --> 00:36:35.280
pioneered the actual film format and the optical

00:36:35.280 --> 00:36:38.039
system. Right. Edison was granted the patent

00:36:38.039 --> 00:36:40.460
for the kinetograph, which was the camera, and

00:36:40.460 --> 00:36:42.380
he built the kinetoscope, which is the peephole

00:36:42.380 --> 00:36:44.559
viewer. That was first publicly exhibited in

00:36:44.559 --> 00:36:47.599
1891. But the sound was still a problem. Dixon

00:36:47.599 --> 00:36:49.460
actually produced the first video with sound

00:36:49.460 --> 00:36:52.699
way back in 1890. But keeping the two synchronized

00:36:52.699 --> 00:36:54.699
outside the controlled environment of the laboratory

00:36:54.699 --> 00:36:56.820
was just too complex for commercial development

00:36:56.820 --> 00:37:00.139
at the time. That difficulty delayed the kinetophone

00:37:00.139 --> 00:37:02.820
for years. It really required a whole separate

00:37:02.820 --> 00:37:05.420
technological revolution decades later to master.

00:37:05.719 --> 00:37:08.300
Despite the sound trouble, his film empire grew

00:37:08.300 --> 00:37:11.420
very quickly. In 1908, he formed the Motion Picture

00:37:11.420 --> 00:37:13.639
Patents Company, which was often called the Edison

00:37:13.639 --> 00:37:16.940
Trust. And his studio made nearly 1 ,200 films,

00:37:17.139 --> 00:37:19.360
including early classics like The Great Train

00:37:19.360 --> 00:37:21.940
Robbery. His chief director, Edwin S. Porter,

00:37:22.179 --> 00:37:24.659
ran the creative side. It's also during this

00:37:24.659 --> 00:37:27.619
period in 1903 that his company filmed that horrifying

00:37:27.619 --> 00:37:31.340
electrocuting an elephant. A deliberate piece

00:37:31.340 --> 00:37:34.079
of anti -AC propaganda using a circus animal.

00:37:34.380 --> 00:37:37.679
And in a final twist of irony, the man who dreamed

00:37:37.679 --> 00:37:40.500
of synchronized sight and sound technology, he

00:37:40.500 --> 00:37:43.219
rejected the final product when it arrived. He

00:37:43.219 --> 00:37:46.079
did. He thought that talkies had spoiled everything.

00:37:46.559 --> 00:37:48.840
He believed they focused too much on the voice

00:37:48.840 --> 00:37:51.690
and that actors had forgotten how to act. He

00:37:51.690 --> 00:37:53.949
even noted that his deafness made him sense this

00:37:53.949 --> 00:37:56.570
imbalance more acutely. The man who invented

00:37:56.570 --> 00:37:58.610
the medium felt the medium had lost its way.

00:37:58.929 --> 00:38:01.289
Now let's turn to his second major industrial

00:38:01.289 --> 00:38:05.530
failure, the battery. In the late 1890s, he set

00:38:05.530 --> 00:38:08.570
out to develop a lighter, more efficient, rechargeable

00:38:08.570 --> 00:38:11.369
battery. Specifically, an alkaline nickel -iron

00:38:11.369 --> 00:38:14.570
battery. He wanted it for his phonographs, and

00:38:14.570 --> 00:38:17.150
more ambitiously, for electric cars, to compete

00:38:17.150 --> 00:38:18.809
with the lead -acid batteries that were common

00:38:18.809 --> 00:38:21.199
then. And this involved an astonishing display

00:38:21.199 --> 00:38:24.360
of just pure perseverance or maybe obstinance.

00:38:24.500 --> 00:38:26.559
His lab tested 10 ,000 different combinations

00:38:26.559 --> 00:38:29.019
of electrodes and solutions to find the perfect

00:38:29.019 --> 00:38:32.039
mix, 10 ,000. He finally got a patent in 1901

00:38:32.039 --> 00:38:34.739
and founded the Edison Storage Battery Company.

00:38:34.900 --> 00:38:37.059
But the invention was plagued with issues right

00:38:37.059 --> 00:38:39.059
from the start. The initial batteries failed

00:38:39.059 --> 00:38:41.980
spectacularly. They would lose their ability

00:38:41.980 --> 00:38:44.440
to hold a charge after just a few recharge cycles,

00:38:44.699 --> 00:38:48.170
forcing a total recall on the product. The company's

00:38:48.170 --> 00:38:50.530
capital was completely wiped out. But Edison

00:38:50.530 --> 00:38:53.429
didn't give up. No. And this shows his profound

00:38:53.429 --> 00:38:56.429
commitment. He paid for the entire recall and

00:38:56.429 --> 00:38:59.090
all the ensuing research out of his own private

00:38:59.090 --> 00:39:01.789
funds. He essentially bought his company back

00:39:01.789 --> 00:39:04.210
from the brink and just refused to abandon the

00:39:04.210 --> 00:39:06.420
problem. How could he afford to fail that big?

00:39:06.619 --> 00:39:09.300
And why did he keep trying? He kept trying because

00:39:09.300 --> 00:39:11.940
he truly believed in electric vehicles and the

00:39:11.940 --> 00:39:14.780
superiority of alkaline batteries. And he could

00:39:14.780 --> 00:39:17.059
afford it partly because of his successful cement

00:39:17.059 --> 00:39:19.059
and lighting royalties, but also because of the

00:39:19.059 --> 00:39:21.260
massive financial network he'd built, notably

00:39:21.260 --> 00:39:23.920
with Henry Ford. Tell us about the Ford link.

00:39:24.280 --> 00:39:27.599
Ford met Edison back in 1896 while Ford was working

00:39:27.599 --> 00:39:30.130
for the Edison Illuminating Company. Ford was

00:39:30.130 --> 00:39:32.590
just deeply enamored with Edison. So when Edison

00:39:32.590 --> 00:39:35.670
faced these massive battery research costs, Ford

00:39:35.670 --> 00:39:38.670
lent him $1 .1 million to continue the research.

00:39:38.909 --> 00:39:41.769
Their friendship and mutual respect lasted their

00:39:41.769 --> 00:39:44.190
entire lives. Unfortunately, the battery story

00:39:44.190 --> 00:39:47.710
also ends in tragedy. It does. Edison was aggressively

00:39:47.710 --> 00:39:49.989
promoting his nickel iron batteries as being

00:39:49.989 --> 00:39:52.610
safer than lead acid batteries for use in submarines.

00:39:52.869 --> 00:39:55.409
The problem is nickel iron batteries leak hydrogen

00:39:55.409 --> 00:39:59.070
gas. And lead acid leak chlorine, which is also

00:39:59.070 --> 00:40:02.510
dangerous. Right. But in January 1916, during

00:40:02.510 --> 00:40:05.670
maintenance on the USS E2, a hydrogen explosion

00:40:05.670 --> 00:40:09.769
occurred and it killed five men. Edison vehemently

00:40:09.769 --> 00:40:12.250
blamed operator error, but the event immediately

00:40:12.250 --> 00:40:14.469
derailed any hope of selling his batteries to

00:40:14.469 --> 00:40:17.190
the Navy. It was over. Shifting to his personal

00:40:17.190 --> 00:40:19.929
life, the sources paint a really complex, often

00:40:19.929 --> 00:40:22.489
difficult picture of a domestic existence that

00:40:22.489 --> 00:40:24.909
was structured entirely around the lab. His first

00:40:24.909 --> 00:40:27.369
marriage was to Mary Stilwell. She was one of

00:40:27.369 --> 00:40:30.130
his 16 -year -old employees and he was 24. They

00:40:30.130 --> 00:40:32.170
had three children, Marion, who he called Dot,

00:40:32.289 --> 00:40:35.449
Thomas Jr., Dash, and William. Edison was often

00:40:35.449 --> 00:40:37.530
neglectful, just prioritizing the laboratory

00:40:37.530 --> 00:40:40.010
above everything else. And Mary died tragically

00:40:40.010 --> 00:40:43.619
young. At 29 of unknown causes. Possibly a brain

00:40:43.619 --> 00:40:46.340
tumor or some sources suggest a morphine overdose.

00:40:46.719 --> 00:40:49.039
And his son, Thomas Jr., he struggled immensely

00:40:49.039 --> 00:40:51.260
living under his father's shadow. It was a public

00:40:51.260 --> 00:40:54.940
humiliation for the family. It was. Thomas Jr.

00:40:55.159 --> 00:40:57.820
got involved in these shady ventures using his

00:40:57.820 --> 00:41:00.400
famous last name to market snake oil products.

00:41:00.619 --> 00:41:03.699
Things like Electrovita and the latest Edison

00:41:03.699 --> 00:41:06.260
discovery, which claimed to be life -extending

00:41:06.260 --> 00:41:09.380
tonics. And the elder Edison had to sue his own

00:41:09.380 --> 00:41:12.179
son. To stop him from using the family name for

00:41:12.179 --> 00:41:14.800
these fraudulent products. It just shows the

00:41:14.800 --> 00:41:17.760
immense tension between the genius inventor and

00:41:17.760 --> 00:41:20.159
the chaotic personal life he often left in his

00:41:20.159 --> 00:41:23.940
wake. His second marriage was in 1886 to Mina

00:41:23.940 --> 00:41:27.000
Miller. She was 20, he was 39. Nikola Tesla,

00:41:27.340 --> 00:41:29.840
who was often a bitter rival, actually made a

00:41:29.840 --> 00:41:32.119
surprisingly insightful observation about Mina.

00:41:32.920 --> 00:41:35.139
He suggested that if Edison hadn't married a

00:41:35.139 --> 00:41:37.159
woman of exceptional intelligence like her, who

00:41:37.159 --> 00:41:39.320
made it her mission to preserve him, he would

00:41:39.320 --> 00:41:41.619
have died years earlier from sheer neglect of

00:41:41.619 --> 00:41:44.039
his own health and basic needs. That detail is

00:41:44.039 --> 00:41:46.739
amazing. The man who systematized the world couldn't

00:41:46.739 --> 00:41:48.719
even organize his own dinner. It illustrates

00:41:48.719 --> 00:41:51.179
the paradox perfectly. He was often neglectful,

00:41:51.280 --> 00:41:53.119
leaving all the housekeeping and child rearing

00:41:53.119 --> 00:41:55.840
entirely to Mina and the staff. Yet when he was

00:41:55.840 --> 00:41:57.920
present, he was extremely controlling. Except,

00:41:57.980 --> 00:41:59.719
of course, for his Fourth of July tradition.

00:42:00.099 --> 00:42:03.280
Right. The deaf man needed an explosive level

00:42:03.280 --> 00:42:06.139
of noise to enjoy the holiday. Because of his

00:42:06.139 --> 00:42:08.679
profound hearing loss, he would make his own

00:42:08.679 --> 00:42:11.739
fireworks and he'd add TNT to them to make sure

00:42:11.739 --> 00:42:13.800
the resulting boom was loud enough for him to

00:42:13.800 --> 00:42:15.820
feel the concussion. That physical limitation

00:42:15.820 --> 00:42:19.360
again driving an extreme response. Always. His

00:42:19.360 --> 00:42:21.860
sons, from a second marriage, they found legitimate

00:42:21.860 --> 00:42:24.780
success. Charles, who took over the company in

00:42:24.780 --> 00:42:27.780
1926, later served as the governor of New Jersey.

00:42:28.170 --> 00:42:30.230
And Theodore became a successful independent

00:42:30.230 --> 00:42:33.030
inventor and physicist. And finally, the ultimate

00:42:33.030 --> 00:42:35.070
anecdote that ties his whole life and his love

00:42:35.070 --> 00:42:37.269
of chemistry together. When he died on October

00:42:37.269 --> 00:42:41.389
18, 1931 at age 84. His last breath was famously

00:42:41.389 --> 00:42:43.789
captured and preserved in a test tube. His son

00:42:43.789 --> 00:42:46.469
Charles sent it to the Henry Ford Museum. as

00:42:46.469 --> 00:42:48.210
a symbol of his father's lifelong dedication

00:42:48.210 --> 00:42:50.650
to chemistry and his profound friendship with

00:42:50.650 --> 00:42:52.989
Ford. So we have the industrialist, the inventor,

00:42:53.110 --> 00:42:55.269
the businessman. What about the man's mind? The

00:42:55.269 --> 00:42:57.730
sources characterize him as a lifelong free thinker,

00:42:57.750 --> 00:43:00.130
heavily influenced by Thomas Paine's scientific

00:43:00.130 --> 00:43:03.090
deism. He had a very specific, non -traditional

00:43:03.090 --> 00:43:05.769
concept of the divine. He stated it pretty clearly.

00:43:06.130 --> 00:43:08.550
I do not believe in the God of the theologians,

00:43:08.630 --> 00:43:10.889
but that there is a supreme intelligence I do

00:43:10.889 --> 00:43:14.130
not doubt. He completely rejected the idea of

00:43:14.130 --> 00:43:16.909
a personal intervening God from organized religion.

00:43:17.130 --> 00:43:20.250
And this led to a lot of controversy. In a 1910

00:43:20.250 --> 00:43:23.070
interview, he was widely labeled an atheist after

00:43:23.070 --> 00:43:26.309
saying, nature is what we know, we do not know

00:43:26.309 --> 00:43:29.050
the gods of religions, and nature is not kind

00:43:29.050 --> 00:43:32.789
or merciful or loving. He used a logical argument

00:43:32.789 --> 00:43:35.230
for it. He said if God made him, he also made

00:43:35.230 --> 00:43:37.309
the fish he ate, and he asked where the mercy

00:43:37.309 --> 00:43:39.559
for the fish came in. but he later clarified

00:43:39.559 --> 00:43:42.300
that he did he explained that his concept of

00:43:42.300 --> 00:43:44.360
nature was the supreme intelligence that rules

00:43:44.360 --> 00:43:47.380
all matter He was a materialist in his belief

00:43:47.380 --> 00:43:50.039
structure. He even explored and promoted ideas

00:43:50.039 --> 00:43:52.559
in panpsychism, which is the theory that consciousness,

00:43:52.900 --> 00:43:55.760
or mind, is a fundamental and pervasive feature

00:43:55.760 --> 00:43:58.800
of all things. That's a deep philosophical framework

00:43:58.800 --> 00:44:01.260
underpinning all of his relentless experimentation.

00:44:02.159 --> 00:44:04.199
Politically, he was a lifelong Republican. He

00:44:04.199 --> 00:44:06.519
supported industrial capitalism and high tariffs

00:44:06.519 --> 00:44:08.940
to protect domestic manufacturing. He moves in

00:44:08.940 --> 00:44:11.639
the highest circles. He met presidents like Rutherford

00:44:11.639 --> 00:44:14.420
B. Hayes and Benjamin Harrison, and he famously

00:44:14.420 --> 00:44:16.690
took those camping trips with Henry Ford and

00:44:16.690 --> 00:44:18.570
Harvey Firestone. They called themselves the

00:44:18.570 --> 00:44:22.210
Vagabonds, acting as this walking, talking advertisement

00:44:22.210 --> 00:44:25.170
for American ingenuity. And his moral compass,

00:44:25.269 --> 00:44:27.510
it seems to have been dominated by pacifism.

00:44:27.869 --> 00:44:30.730
Yes. When he was asked to serve as a naval consultant

00:44:30.730 --> 00:44:33.369
during World War I, he stipulated that he would

00:44:33.369 --> 00:44:36.329
only work on defensive weapons. He stated later,

00:44:36.489 --> 00:44:38.510
I am proud of the fact that I never invented

00:44:38.510 --> 00:44:41.219
weapons to kill. He helped the Navy with things

00:44:41.219 --> 00:44:44.280
like locating submarines, but he refused to develop

00:44:44.280 --> 00:44:46.739
offensive weaponry. He was also an early and

00:44:46.739 --> 00:44:49.400
practical supporter of women's suffrage. Stating

00:44:49.400 --> 00:44:51.780
in 1915, every woman in this country is going

00:44:51.780 --> 00:44:54.440
to have the vote. And he backed that up practically.

00:44:54.699 --> 00:44:57.199
He employed women in factory jobs that required

00:44:57.199 --> 00:45:00.219
nimble fingers, like making brush wires for dynamos,

00:45:00.300 --> 00:45:02.579
acknowledging their dexterity and their capability

00:45:02.579 --> 00:45:05.179
in the industrial process. And finally, he even

00:45:05.179 --> 00:45:07.599
tried to invent a better financial system. In

00:45:07.599 --> 00:45:10.199
1922, he published a proposed amendment to the

00:45:10.199 --> 00:45:12.760
Federal Reserve Banking System. He was advocating

00:45:12.760 --> 00:45:15.440
for a commodity -backed currency that would remove

00:45:15.440 --> 00:45:18.099
control from the traditional banks. It failed

00:45:18.099 --> 00:45:20.579
to get any legislative support, but it just shows

00:45:20.579 --> 00:45:23.760
the scale of his systematic mind. He was applying

00:45:23.760 --> 00:45:25.980
his R &D principles to economics and national

00:45:25.980 --> 00:45:29.219
policy. This has been a true deep dive into Thomas

00:45:29.219 --> 00:45:32.440
Edison, far, far beyond the light bulb filament.

00:45:32.659 --> 00:45:36.000
We've explored the sheer just... bizarre inventory

00:45:36.000 --> 00:45:39.139
of Menlo Park, a physical manifestation of his

00:45:39.139 --> 00:45:42.300
relentless R &D process. We witnessed the devastating

00:45:42.300 --> 00:45:44.880
DC limitations that led to that bitter merger

00:45:44.880 --> 00:45:47.079
that created General Electric and the massive

00:45:47.079 --> 00:45:49.539
catastrophic industrial failure of the Ogdensburg

00:45:49.539 --> 00:45:52.539
mine that somehow laid the groundwork for his

00:45:52.539 --> 00:45:54.920
quiet, profitable success in the cement business.

00:45:55.219 --> 00:45:57.300
And ultimately, the takeaway is the systematic

00:45:57.300 --> 00:45:59.920
nature of his work. He didn't just invent, he

00:45:59.920 --> 00:46:02.559
industrialized invention itself. He showed that

00:46:02.559 --> 00:46:05.880
systematic, relentless effort, coupled with massive

00:46:05.880 --> 00:46:08.039
capital investment and an astonishing tolerance

00:46:08.039 --> 00:46:10.960
for failure, like that battery recall where he

00:46:10.960 --> 00:46:13.460
paid millions out of his own pocket, that's the

00:46:13.460 --> 00:46:16.739
recipe for modern innovation. He taught the world

00:46:16.739 --> 00:46:19.960
how to fail fast, learn from the data, and scale

00:46:19.960 --> 00:46:22.260
up the next attempt. So what does all this mean

00:46:22.260 --> 00:46:25.880
for you, the learner? Edison's story is a profound

00:46:25.880 --> 00:46:28.420
lesson in the business of creativity and the

00:46:28.420 --> 00:46:31.480
absolute necessity of systematic failure. His

00:46:31.480 --> 00:46:33.960
failures, whether it was in mining or in battery

00:46:33.960 --> 00:46:36.699
technology or even in his family life, they were

00:46:36.699 --> 00:46:39.639
data points that informed his next, often massive,

00:46:39.739 --> 00:46:42.320
success. It shows that true expertise isn't about

00:46:42.320 --> 00:46:44.920
avoiding mistakes. It's about being able to afford

00:46:44.920 --> 00:46:47.780
both mentally and financially to keep going after

00:46:47.780 --> 00:46:50.159
they inevitably happen. And here is the provocative

00:46:50.159 --> 00:46:52.619
final thought we want to leave you with. Despite

00:46:52.619 --> 00:46:54.980
his profound hearing loss, Edison fought tooth

00:46:54.980 --> 00:46:57.639
and nail for years to personally approve every

00:46:57.639 --> 00:46:59.659
single musical record released by his company.

00:46:59.880 --> 00:47:02.119
He was experiencing that art in a fundamentally

00:47:02.119 --> 00:47:05.059
different physical way as vibrations transmitted

00:47:05.059 --> 00:47:06.960
through his teeth. Which raises an important

00:47:06.960 --> 00:47:09.880
question. When we talk about invention and innovation,

00:47:10.119 --> 00:47:12.460
how much of the final product is defined not

00:47:12.460 --> 00:47:14.920
by the creator's boundless ability, but by their

00:47:14.920 --> 00:47:17.920
own unique physical and often frustrating limitations?
