Jun 19, 2012 · Turing's breakthrough in 1942 yielded the first systematic method for cracking Tunny messages. His method was known at Bletchley Park simply as Turingery, and the broken Tunny messages gave ...
Feb 23, 2022 · Many famous Codebreakers including Alan Turing, Gordon Welchman and Bill Tutte were found this way. Others such as Dilly Knox and Nigel de Grey had started their codebreaking careers in WW1. The organisation started in 1939 with only around 150 staff, but soon grew rapidly.
During World War II some encipherment was still carried out by hand, but for most messages electrical code and cipher machines were used. The Germans had several including the Enigma machine, the Lorenz SZ40 and the Siemens Geheimschreiber.
The German Navy, rightly suspicious that their code had been cracked, introduced a fourth wheel into the device, multiplying the possible settings by twenty six. The British finally broke this code that they called 'Shark' in December 1942.
They were members of the Government Code and Cypher School, a secret team of scholar turned code breakers. Their mission: to crack the Nazi codes. The most famous of the code and cyphers to be broken at Bletchley Park was the enigma machine cypher.

Aug 2, 2024 · Chief among the code-breakers was mathematician Alan Turing, who invented the Turing Bombe, a device that turned the letters produced by Enigma into legible German. With its rows of wheels and dials, it is tempting to call the Bombe a prototype computer, but it is in fact an electromechanical device that carried out a systematic search to find ...
