A recognized genius in mathematics, cryptography, and computer science, Alan Turing cracked German naval code in World War II, and is thought to be the father of modern computer science. Despite his achievements he was treated poorly in his home country of Great Britain, which prosecuted him for homosexual acts, which were illegal at the time. That treatment likely led to his suicide in 1954 at the age of 41.

John Graham-Cumming, a British computer programmer, believes Turing is owed an apology.
