The Birth of Morse Code
1836-1844Samuel Morse, along with his assistant Alfred Vail, developed morse code in the 1830s. The system was designed to work with the electromagnetic telegraph, which Morse had been developing since 1832. The first message sent by telegraph was "What hath God wrought" on May 24, 1844, transmitted from Washington D.C. to Baltimore.
The original morse code was quite different from what we use today. It only transmitted numerals, which were then looked up in a codebook to translate into words. Alfred Vail expanded the code to include letters and special characters, creating what we now know as American Morse Code.
