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.
The clattering of typewriters and the hum of early computers hidden inside a small manor in the English countryside was the site of one of WWII's most pivotal battles: codebreaking. At Bletchley Park, brilliant minds worked tirelessly to decrypt enemy messages.
While Bletchley Park and the Enigma machine are well known, many British codebreakers learned their trade during the First World War. This is the story of Britain’s early codebreakers, their humble beginnings and their incredible impact.

From 1941 onwards, Bletchley's experts focused upon breaking the codes used by German U-boats in the Atlantic. In March 1941, when the German armed trawler 'Krebs' was captured off Norway complete with Enigma machines and codebooks, the German naval Enigma code could finally be read.
Take a look at the history of code-breaking and how this became so important during World War II. Code-breaking during World War II descends from a long and ancient tradition. Ciphers have been in existence almost as long as writing itself. The ancient Egyptians used them for religious purposes and there are possible references to the use of ...
Alan Turing was one of these academics: he was recruited in 1938 and sent on a training course to learn about codes (and the Enigma machine) early in 1939.
