Alfred Vail: The Man Who Built the Morse Alphabet PEOPLE OF THE WIRE | MORSE CODE WORKS Everyone knows the name Morse. Far fewer know Alfred Vail, the skilled machinist whose hands built the first working telegraph apparatus and whose thinking shaped the alphabet itself. Morse's original plan sent numbers that stood for words in a codebook. Vail helped turn it into a system that sent letters directly. The famous story is the type case: to decide which letters deserved the shortest signals, Vail studied how much type a printer kept for each letter. The letters a printer needed most - E, T, A, O - became the quickest to send. Key points - Vail's family ironworks at Speedwell hosted the first public demonstrations - Letter frequency, not alphabet order, decided the code lengths - Vail operated the Baltimore end during the first line's opening in 1844 - Modern Morse is a team product: Morse the promoter, Vail the engineer Try it yourself Translate any text to Morse code and hear it with sound, free: Click Here
