I'm so happy to hear Alan Turing's story being told, even if it is by way of a Hollywood movie. Turing was part of the British cryptographic team at Bletchley Park that cracked the German Enigma code during World War II.
Did Polish cryptographers crack the Nazi Enigma code before Alan Turing?
An Enigma Machine in use in The Enigma was a complex cryptography tool used by the Axis—and cracked by the allies—in World War II. Allen Turing, a British cryptologist, broke the Enigma Code, which did mortal damage to the German war machine.
