Is Alan Turing really this code-breaking god we show him to be? Or are his efforts exaggerated? It has been said he shortened the war by two years. He certainly did not invent the Enigma machine. It was invented by Arthur Scherbius at the end of World War One. Intercepting and deciphering of German messages was taken before the Nazis had even gotten power. The Polish Cipher Bureau had started in December of 1932. I know that the Poles had shared their encryption cracking methods with British and French intelligence. So is it really fair to say that because of the Poles, we were able to win the war? I am not trying to say they were perfect, as the British had made some changes to meet increasing complexity of the German messages. But to say that Alan Turing was responsible for shortening the war is just overstating his potiential. The person who said was responsible for shortening the war by two to four years was Winston Churchill, who I doubt even knew how crptography worked. I always saw Turing as more a guider who oversaw other cryptologists break the code to help the effort. So, Alan Turing, responsible for helping win the war, or just an exaggerated mathematician?
