Alan Turing on British money
by Ed Sawicki - June 2021
The Bank of England will issue a 50 pound note featuring Alan Turing on June 23, 2021, Turing's birthday. He died on June 7, 1954 at the age of 41.
Turing is best known for his work at Bletchley Park during World War II breaking German codes—most famously, the code used by the German Enigma machine. Turing's work helped the Allies win the war.
However, this didn't stop the British legal system from prosecuting Turing for being gay in 1952. If the British public did anything to intervene on his behalf, it was not successful. Gayness was a serious crime in Britain in those days but so was rock and roll less than a decade later.
Turing was faced with a choice of prison or chemical castration. He accepted the latter but this admission of guilt removed his security clearance and barred him from continuing his work for the British signals intelligence agency (GCHQ).
In 1955, he died from cyanide poisoning, ruled a suicide.
On September 10, 2009, Prime Minister Gordon Brown apologized for how Turing was treated. On December 24, 2013, Queen Elizabeth II signed a pardon for Turing's conviction for “gross indecency”. Honoring Turing with a 50 pound note in 2021 is further recognition of his contribution.
Some press reports say that Turing is the first gay man to appear on British money—but really, what are the chances of that?
