Alan Turing was a British mathematician, computer scientist, and cryptologist, among other things. He is best known for helping to crack the Enigma machine used by the Germans to encrypt transmissions during World War II. Turing is considered the father of theoretical computer science and artificial intelligence. He was a homosexual, which was still considered a crime during his lifetime. He was convicted of the crime and underwent estrogen injections instead of going to jail so that he could continue his work. Unable to cope with the treatment, he committed suicide by cyanide poisoning.
Turing is a surname of Scottish origin, first appearing in the 14th century as the name Turin. I think this name would be best in the middle spot, as an homage to Alan Turing's life. The name does not appear as a first name in the Social Security Administration's name database.
