He Broke The German Enigma Code During The WW2
Turing arrived at the Government Code and Cypher School's wartime station at Bletchley Park on September 4, 1939, the day after the UK declared war on Germany (GCCS). At Bletchley Park in Buckinghamshire, where top-secret work was done to break the military codes employed by Germany and her allies, Turing began working there full-time. The "Enigma" code was the main focus of Turing's work at Bletchley.
The German military employed the Enigma, a specific sort of enciphering device, to convey encrypted messages. Despite the fact that Polish mathematicians had figured out how to decipher Enigma communications and had informed the British of their discovery, the Germans strengthened Enigma's security at the start of the war by regularly updating the encryption system. This made it considerably more challenging to decipher the code. Turing was instrumental in this, co-inventing the Bombe computer with fellow code-breaker Gordon Welchman. The work of the codebreakers was greatly lessened thanks to this technology. German Air Force signals began to be read at Bletchley in the middle of 1940, and the intelligence gleaned from them aided the war effort. His bomb invention is thought to have cut the European conflict by two to four years. The majority of Alan Turing's work at Bletchley Park is referenced in the 2014 Oscar-winning film The Imitation Game.
