#GERMAN ENIGMA MACHINE CODE#
The work of Alan Turing and his team in cracking the Enigma code is the focus of the 2014 movie, "The Imitation Game," based on the book, Alan Turing: The Enigma, by Andrew Hodges. While there, he also saw the latest American progress on a top-secret speech-enciphering system, and when he returned to Bletchley, he eventually developed a speech-scrambling device he named “Delilah.” Turing traveled to the United States in December 1942 to advise US military intelligence in the use of Bombe machines and to share his knowledge of Enigma. The ability of Bletchley to read these contributed greatly to the Allied war effort. In July 1942, Turing developed a complex code-breaking technique he named “Turingery.” This method fed into work by others at Bletchley in understanding the “Lorenz” cipher machine, which enciphered German strategic messages of high importance. With the help of captured Enigma material, and Turing’s work in developing a technique he called “Banburismus,” the naval Enigma messages were able to be read from 1941. German U-boats were inflicting heavy losses on Allied shipping and the need to understand their signals was crucial. Turing also worked to decrypt the more complex German naval communications that had defeated many others at Bletchley.
This device helped to significantly reduce the work of the code-breakers, and from mid-1940, German Air Force signals were being read at Bletchley and the intelligence gained from them was helping the war effort. Turing - along with fellow code-breaker Gordon Welchman - invented a machine known as the Bombe.
