Today is the centenary of his birth, Alan Turing is widely considered to be the father of computer science and artificial intelligence. And persecuted for his homosexuality. At 39, Turing is arrested and tried for gross indecency because of his relationship with a Manchester man; Turing becomes outspoken about his homosexuality. He chooses estrogen treatments over prison time. Some say the treatments take a heavy toll on him not only physically, but mentally. In 2009, Prime Minister Gordon Brown officially apologizes for the British government’s postwar treatment of Turing — but there still is no pardon.
