Did Samuel Morse really invent the telegraph and the code that bears his name?
The name on the code went to Morse, the machinist who built the machine at his own expense got a quarter share, and a rival British team had a telegraph whose operators did not need to learn a code.
▶ Start the storyMorse was one of several people who built a working telegraph, and he developed his code together with his assistant Alfred Vail. His is the name that stuck, and he went to great lengths to win a lawsuit for the right to be called its inventor.
Telegraph ideas were in the air. In 1828 Joseph Henry showed that a more powerful electromagnet could operate a telegraph through the high resistance of long wires. In 1833 Carl Friedrich Gauss and Wilhelm Weber strung a 1,200-metre wire over the roofs of Göttingen. In Britain, William Fothergill Cooke and Charles Wheatstone patented a needle telegraph in May 1837. Its first commercial line, in 1838, showed the letter being sent, so operators did not need to learn a code.

"What hath God wrought"
Samuel Morse independently developed and patented a recording telegraph the same year, and his assistant Alfred Vail developed the register that recorded the messages. Morse and Vail developed the Morse code alphabet together. Vail negotiated an arrangement to build the machine at his own expense, in return for 25% of the proceeds, and he invented the first sending key.
The credit did not stay even. Morse later cut the Vail brothers' share to one-eighth and kept the patent rights to the apparatus and the code, and Vail left the industry in 1848 because he felt Morse's managers did not value his contributions. Morse went to great lengths to win a lawsuit for the right to be called "inventor of the telegraph". When he sent the historic first message, "WHAT HATH GOD WROUGHT", on 24 May 1844, the person receiving it was Vail.

Recap
Morse and Vail made the code, Cooke and Wheatstone made needles, and the credit was settled by patents and courts.
💡 A trick to remember it · Henry made the magnet, Vail made the key, Morse made the patent and kept the name.
Surprising fact · The first sending key was invented by Vail, and the first message was received by him.
