The Bank of England has unveiled its new £50 banknote featuring the mathematician and computer scientist Alan Turing.
Turing is best known for his codebreaking work at Bletchley Park, which helped end the Second World War.
The polymer £50 will be issued for the first time on 23rd June 2021, which coincides with Alan Turing’s birthday.
The note contains advanced security features, including two windows and a two-colour foil, which The Bank of England says makes it very difficult to counterfeit. There is also a hologram image which changes between the words ‘Fifty’ and ‘Pounds’ when tilting the note from side to side.
As with the polymer £10 and £20, it will contain a tactile feature to help vision impaired people identify the denomination.
The £50 note will join the Churchill £5, the Austen £10 and the Turner £20, meaning all Bank of England banknotes are now available in polymer.
The public can continue to use paper £50 notes as usual. Notice will be given at least six months ahead of the date when the old paper £50 is withdrawn.
Commenting on the new note, governor Andrew Bailey said: “There's something of the character of a nation in its money, and we are right to consider and celebrate the people on our banknotes. So I’m delighted that our new £50 features one of Britain’s most important scientists, Alan Turing. Turing is best known for his codebreaking work at Bletchley Park, which helped end the Second World War. However in addition he was a leading mathematician, developmental biologist, and a pioneer in the field of computer science. He was also gay, and was treated appallingly as a result. By placing him on our new polymer £50 banknote, we are celebrating his achievements, and the values he symbolises.”
