This is the story of how a flawed machine, a brilliant mathematician, and the world’s first programmable computer helped shorten the war by years and save countless lives. Invented by German engineer Arthur Scherbius after WWI, the Enigma was a portable cipher machine that looked like a typewriter in a wooden box. Its genius lay in its complexity. When an operator typed a letter, a series of rotating wheels (called rotors ) and a plugboard would scramble it into a different letter. For example, typing "A" might light up "Z."
ULTRA provided proof of where U-boats were hunting, allowing convoys to reroute and avoid slaughter. It revealed Hitler’s troop movements before the D-Day landings. Historians estimate that breaking the Enigma code shortened the war in Europe by two to four years. codigo enigma
By 1941, thanks to Turing’s Bombe and clever "cribs" (often derived from weather reports or the phrase "Heil Hitler"), the Allies were reading German naval messages in near real-time. The intelligence gleaned from breaking Enigma was codenamed ULTRA . It was considered the war’s greatest secret—so sensitive that many Allied field commanders didn’t even know the source.
