Alan Turing at Bletchley Park in World War II

  • Tony Sale


“There should be no question in anyone’s mind that Turing’s work was the biggest factor in Hut 8’s success [in breaking the German Naval Enigma]. In the early days he was the only cryptographer who thought the problem worth tackling and not only was he primarily responsible for the main theoretical work within the hut (particularly the developing of a satisfactory scoring technique for dealing with Banburismus) but he also shared with Welchman and Keen the chief credit for the invention of the Bombe. It is always difficult to say that anyone is absolutely indispensable but if anyone was indispensable to Hut 8 it was Turing” [1].
