Alan Turing
Installing the first Bombe
Bletchley, Milton Keynes, Buckinghamshire, England, United Kingdom
Within weeks of arriving at Bletchley Park, Turing had specified an electromechanical machine called the bombe, which could break Enigma more effectively than the Polish bomba kryptologiczna, from which its name was derived. The first bombe was installed on 18 March 1940.
