Mark Carney, governor of the Bank of England, speaks in front of the concept design for the new Bank of England fifty pound banknote, featuring mathematician and scientist Alan Turing, during the presentation at the Science and Industry Museum in Manchester, north-west England on July 15, 2019. Alan Turing, a mathematician and codebreaker who deciphered German World War II messages, will appear on Britain's new 50 pound note. The Bank of England made the announcement Monday that Turing, who died in 1954, would appear on the currency and some of his work would also adorn the note. The action continues the posthumous accolades for the scientist, who after the war was charged with gross indecency after admitting to having a homosexual relationship, which was illegal at the time in Britain. To avoid imprisonment, he chose chemical castration with female hormones.
