During World War II, British mathematician Alan Turing, regarded as the father of modern computing, led a team at Britain's Bletchley Park code breaking center, which cracked the cipher system in 1941.
The breakthrough helped the Allies decipher crucial radio messages about German military operations. Historians estimate that it shortened the war by about two years. Only hubris led to the Nazi code being cracked: the insistence on signing some messages with ‘HH’(Heil Hitler) ultimately provided the weak spot that the code breakers were able to exploit.
The story of Turing and his team was made into a 2014 movie called The Imitation Game, starring Oscar-nominated UK actor Benedict Cumberbatch.
