Alan Turing was, in fact, the person who came up with the concept of the Turing test, yes. He was also a mathematician who was instrumental in breaking the German Enigma code and thereby winning WWII.

And, yes, he was gay, and chemically castrated to "control" his "illness." And he committed suicide. The debt that the non-Nazi world owes to the man didn't become public until decades after his death.
