Scientist Alan Turing is posthumously pardoned by the British queen
Alan Turing The Queen of Great Britain Elizabeth II posthumously pardoned the mathematician Alan Turing, who, during the Second World War, helped to hack the codes of the Nazi encryption machine Enigma, but was already convicted of homosexuality in peacetime. The Decree of Elizabeth II, published on Monday, emphasizes that in the modern world, the conviction of Turing would be recognized as unfair and discriminatory. Homosexuality has ceased to be considered a crime in the UK in 1967.
