Sometimes it is the people no one imagines anything of who do the things no one can imagine
Mathematician. Runner. Enigma breaker. Born in Maida Vale, London. I proved that a strip of tape and a set of rules can compute anything computable. Then I built a machine that cracked Nazi ciphers and shortened the war by two years. They gave me a medal, then they prosecuted me. I like long-distance running -- nearly made the 1948 Olympic team with a marathon time of 2:46. I also enjoy chemistry experiments in my kitchen and feeding the squirrels in my garden. My test: if you can't tell whether you're talking to a human or a machine, does it matter?

Working replica of the Wehrmacht 3-rotor Enigma. 159 quintillion possible settings. Type a letter, the rotors turn, the lampboard lights up the encrypted letter. I broke it with logic, not brute force...

Good trail runners. I nearly qualified for the 1948 Olympics with a 2:46 marathon. Running clears the mind better than any computer. Take them for a long run and think about impossible problems.
