A Comm for Historymemes

Explanation: Alan Turing was a mathematician and computer scientist whose revolutionary work during WW2 helped the British shorten the war considerably by breaking (and thus having access to) Nazi coded messages.

A little over half a decade after the war, a chance break-in at his house led to him accidentally incriminating himself - by admitting to the presence of his boyfriend. This being the 1950s UK, the courts gave him a choice for the horrific crime of homosexuality - chemical castration, or several months in prison. Turing considered that he would not last in prison, and opted for the chemical treatment. Some time later, he bit into an apple laced with cyanide and died, which many consider to be an act of suicide (though it is still disputed, some believe it was genuinely an accident).
