Before he became known for the code that bears his name, Samuel Morse was a portrait painter. Soon after setting up an art studio in Boston in 1815, Morse married Lucretia Walker. All was good and well until 1825, when tragedy after tragedy plowed its way into Morse's life. Lucretia died in 1825 after giving birth to the couple's third child. She fell seriously ill while Morse was away working on a painting commission, and got word of her condition too late (giddy-up, you darn horse messengers!). By the time he made it back home to be with her, she had already been buried. On top of that, the next year, his father died. Three years after that, his mother died. Can't a dude catch a break?!

After all this heartbreak, Morse (along with some inventor pals he befriended along the way) began contemplating telegraphy. If he would've received news of his wife's illness sooner, he could've made it back in time to be with her before she passed. The solution, he thought, could have been in the wires. The telegraph had already been in invented in 1774, but the impractical device used 26 bulky wires to transmit messages. Morse developed a way to send messages over a single wire and created a "language" — Morse code, a system of long and short signals — to go with it.

He received a patent for his telegraph invention in 1844, and was able to secure funding from Congress to build wires across the United States. On May 24th of that year, he telegraphed his famous message from Baltimore to Washington: "What hath God wrought!" According to PBS, President Abraham Lincoln received battle reports at the White House via telegraph during the Civil War. The technology rapidly caught on with ordinary people too. Before long, Morse's practical little invention change the course of the modern world.
