Who Invented the Telegraph? Joseph Henry, A Bored Math Teacher!

Joseph Henry, not Samuel Morse, invented the telegraph. With the possible help of a black assistant who was restricted from publishing (and beaten for his "impudence"), learn why a bored math teacher would invent the telegraph and why he didn't profit from it.

As usual, the amazing music is from the fabulous Kim Nalley.

Almost all new info to me and I’m loving it! Great pacing. Just killing it in this niche. Bravo

While Morse may be popularly credited with the invention of the telegraph, I only credit him with creating the first encoding system that bears his name. The telegraph was worked on by so many people before him that the idea was old news by the time of his demonstration. Another point on Henry, he has an electrical unit named after him thanks to the vast improvements he made upon others work.

Yes, the inductance of coils of wire is measured in Henries, H, mH, etc.

Henry was Princeton’s first super-star professor. Henry house is right next to the main gate and Nassau Hall. Unfortunately none of Henry’s original experimental equipment survived and had to be recreated much later.

This channel is amazing. Thank you so much

[@johnopalko5223]

At least he had the SI unit of inductance named after him.

Great story! You’re stringing me along and I like it!

Amazing

[@J.Crooner]

ABSOLUTELY FANTASTIC🤘😝🤘POST, I LOVED EVERY MINUTE OF IT👍😁😎😉😊

[@Kathy_Loves_Physics]

So glad you liked it. Cheers.

[@J.Crooner]

YOUR VIDEOS ARE ABSOLUTELY GREAT DO YOU HAVE AN INSTAGRAM PAGE👍😁💪😎💪🙏😉

JASON SQUIRE just noticed this and ... no should I?

[@robbirdjonesanimal8869]

Very good stuff, will probably have to watch them all

[@budokai6706]

Awesome! Thank you

[@martinmalloy8119]

i can t understand why so few people watch your fantastic videos, probably it s more important what make up one wears....

No he didn't, there lots of different types of telegraphs before him with Sir Frances Ronalds credited as inventing the first working electric telegraph in 1816, decades before Joseph Henry with his early doorbell.

[@joeswampdawghenry]

Cheers!

[@alastairchestnutt6416]

I think that there may have been an earlier functioning electrostatic telegraph.

[@Kathy_Loves_Physics]

There was, and I mentioned it in my next video, but the basics of the telegraph used in the 1800s was invented by Henry.

[@joeswampdawghenry]

Joseph Henry was not racist.. He used to share his lunch with his assistant sam.

Read 2 learn or watch you like wow

[@ZeldaTheSwordsman]

Didn't the Simpsons reference this at one point?

[@daleeasternbrat816]

Mr. Henry shoiuld have patented immediately.

[@richardmiranda640]

We must keep our comments respectful but it’s ok for you to call Morris a loathsome thief.

[@Kathy_Loves_Physics]

Morris?

[@marcusdirk]

Well, she tells Morse's story in the next video: we can make our own minds up once we've heard it - he's unlikely to be offended 😉

[@POLMAZURKA]

get rid of virtue - signaling...............

Having a theme song that just repeats the same word over and over at the beginning and end of your video is extremely annoying. It's not a cute song, it just gets stuck in your head, and so I will not be watching your channel, even though it was good otherwise. I'm not exposing myself to that kind of psychological warfare that tries to force things into my mind by repeating them over and over.
