28. Samuel Morse
- Most Famous For Inventing: Morse Code, Single-Wire Telegraph System
While Samuel Morse did not invent the first telegraph, his version of a single-wire system became a much more efficient way of doing things. In fact, during the American Civil War, several wires were put up to send messages from place to place. This would lead to the inspiration behind how the telephone worked. Technically, Samuel Morse beat others to the electromagnetic telegraph by a year too.
This is according to the patent submitted, on display today at the Smithsonian Institution. While he is now the “sole inventor,” people did not know him as this when he was alive. He did, however, invent Morse Code. This is the primary language in use for telegraphy, making him one of the world’s greatest inventors. Many in the Armed Forces still use forms of Morse Code to this day!
