Breaking the Code Breaking the Code Breaking the Code is a 1986 play by Hugh Whitemore about British mathematician Alan Turing, who was a key player in the breaking of the German Enigma code at Bletchley Park during World War II and a pioneer of computer science. The play thematically links Turing's cryptographic activities with his attempts to grapple with his homosexuality. It was adapted as a 1996 television film directed by Herbert Wise, with Derek Jacobi reprising his stage role as Turing. Following an eight-month run at the Theatre Royal, Haymarket in London's West End beginning on 21 October 1986, the play
Cryptanalysis of the Enigma death in February 1943, was the solving, in 1941, of the "Abwehr" Enigma. Intercepts of traffic which had an 8-letter indicator sequence before the usual 5-letter groups led to the suspicion that a 4-rotor machine was being used. The assumption was correctly made that the indicator consisted of a 4-letter message key enciphered twice. The machine itself was similar to a Model G Enigma, with three conventional rotors, though it did not have a plug board. The principal difference to the model G was that it was equipped with a reflector that was advanced by the stepping mechanism once it
