A delayed royal pardon

Alan Turing was the father of computing -- check out the Turing Machine and the Turing Test sometime. He was also instrumental during WWII of breaking some of Germany's encryptions and shortening the war. Alas, he was also gay and in 1950s Britain that was a crime. In 1952 he was convicted of gross indecency and sentenced to chemical castration. Two years later he killed himself.

Finally, sixty years later, the Queen has granted a royal pardon. It took a while for laws and public perceptions to catch up.
