Man Behind Morse Code

Beginning in 1836, Samuel F. B. Morse and Alfred Vail developed an electric telegraph, which sent pulses of electrical current to control an electromagnet that was located at the receiving end of the telegraph wire. The technology available at the time made it impossible to print characters in a readable form, so the inventors had to devise an alternate means of communication. Beginning in 1837, William Cooke and Charles Wheatstone operated electric telegraphs in England, which also controlled electromagnets in the receivers; however, their systems used needle pointers that rotated to indicate the alphabetic characters being sent.

In contrast, Morse and Vail's initial telegraph, which first went into operation in 1844, made indentations on a paper tape when an electrical current was transmitted. Morse's original telegraph receiver used a mechanical clockwork to move a paper tape. When an electrical current was received, an electromagnet engaged an armature that pushed a stylus onto the moving paper tape, making an indentation on the tape. When the current was interrupted, the electromagnet retracted the stylus, and that portion of the moving tape remained unmarked.

The Morse code was developed so that operators could translate the indentations marked on the paper tape into text messages. In his earliest code, Morse had planned to only transmit numerals, and use a dictionary to look up each word according to the number which had been sent. However, the code was soon expanded to include letters and special characters, so it could be used more generally. The shorter marks were called "dots", and the longer ones "dashes", and the letters most commonly used in the English language were assigned the shortest sequences.

Your secret is safe with me. Actually, this is more history than the regular History Channel has been showing lately. I'm tired of the end of days, UFO's and loggers.

So, Morse was a douche bag... at least could have tried to get Vail's name in there somewhere...

im related to him cause if you look on ansetory .com it will till you my great grand mother was married to charles "chips" morse that was his great great great great great grandson and i have his hat his great great great great grandson made the ruby lazer and the first water purification system .

Why doesn't History Channel broadcast this stuff all day? I would watch it. Instead we get marathons of American Pickers and Pawn Stars. YUCK.

ugh, i hate science homework that you have to watch videos for and then answer questions

welcome to history the same thing happened with Nikola Tesla and Edison

It doesn't souls believable, but Samuel morse is my great-great-great-great-great grandfather.

We 8should go through and rename mores code to vails code
