Gordon Welchman

William Gordon Welchman (June 15, 1906 ? October 8, 1985) was a British mathematician and World War II codebreaker at Bletchley Park. Welchman envisioned an enhancement to Alan Turing's design for an electromechanical codebreaking machine, the bombe. Welchman's enhancement, the "diagonal board," rendered the device more efficient in breaking messages enciphered on the German Enigma machine. Bombes became a primary tool for decrypting Enigma during the war.
