Alan Turing, father of computer science, finally gets royal pardon

If you don't know who Alan Turing was, then shame on you. The British code breaker, mathematics genius and father of both computer science and artificial intelligence is rightly credited with helping to bring the second world war to an end. Turing was also gay, and that's where the shame has stuck firmly on the UK establishment for more than 60 years. Turing was convicted for 'homosexual activity' in 1952, and his punishment was to be chemically castrated.
