Hearing professors lecture, and watching a few documentaries have lead me to discover a few things about Thomas Edison. For example, we had electric light long before Edison “invented” the light bulb. He just discovered the filament needed (Joseph Swan got the patent first). He ripped off Nikola Tesla for lots of money, and killed animals to make AC power look bad.
My question is, are there any other things about Thomas Edison that you won’t find in most history books? Secondly, why does he get credit for the light bulb, while Swan fades into obsurity? Learning what I have, I’m just curious.
Edison owned patents for DC transmission systems. He wouldn’t make as much money if everybody in the US got wired with AC. Apparently, Edison liked the concept of enriching himself more over the inconvenience of DC.
He understood the processes of commercial development far better than some of his rivals, many of whom had a better grasp of the fundamental research or scientific theory, but no business sense. Which is no small thing. What he REALLY invented was the modern industrial R&D process. He turned research from a cottage industry by an individual tinkerer into something turned out by a research laboratory. Indeed, many of the inventions we associate with him came from his organization, not him personally.
For little known things, you might look up his experiments with goldenrod as a source of rubber. He had plantations in florida cultivating the stuff.
Then there’s this:
Tim Powers used “Edison’s Last Breath” as a device in one of his novels.
Edison himself had a certain amount of belief in spritualism, which wasn’t entirely uncommon in his day, even among scientists like William Crookes. Edison supposedly tinkered around trying to concoct a device to talk to the spirits of the dead.
You are right about there being a war between Edison and Tesla over AC/DC and even though Tesla won he did not get the credit he should have.
Actually Edison didn’t invent the idea of the light bulb, he just invented the filament that would make using light bulbs practical.
So he is responsible for the light bulb being available to the public, Swan was not.
I think the Invention that shook his world was when Edison announced that he could record and reproduce human speech.
This was incredible to his contemporaries, and outside his feild really, which wasn’t really mechanical invention until then.
Many of science’s leading lights of the day (including Edison enemy A. Graham Bell) when hearing about the talking machine, pronounced it a fraud and a hoax, Thorized that maybe it was done by a concealed ventriloquist.
(This is me ripping off a biography of Edison) There existed conceptual barriers to the men of the day which made the feat seem more difficult than it actually was. It may have been no more than the concept that sounds are transitory & him changing that.
In any event, this is discovery more than any other in his lifetime, which made him a “Wizard”, and appear larger than life until this very day.
I don’t mean this to knock Edison any more than that site does, either. He was the motive force behind a lot of the stuff - it was HIS research lab, after all, and he was undoubtedly a very “hands on” manager and called the shots when it came to what he wanted his staff to be doing.
Edison had one huge but little remembered failure–he came up with a method for producing iron from low grade ore, but no matter how much money he pored into the venture over a decade of development, it never proved economical. See Edison’s Big Failure or more details.
