If you have a passing interest in the life of Alan Turing and the innovations he was responsible for, there's some small way you can help -- signing a petition to have him pardoned of his "crime."
In 1952, Turing was convicted of "gross indecency" with a man, back in the days when being gay was still considered a crime in the UK, and during a period of harsh police crackdowns on homosexuals. Alan was then chemically castrated, before commiting suicide, aged 41, two years later.
We've already seen similar efforts to restore Turing's reputation. Back in 2009, then PM Gordon Brown issued a thorough apology for the way he was treated. This latest attempt would have Alan completely pardoned of the incident, although it would seem unlikely to succeed. In Gordon's apology, specific mention was made to the way Turing was "dealt with under the law of the time and we can’t put the clock back."
