Bravery seen in war and life
Codebreaking hero Turing, who later faced anti-gay bias, is newest face on UK note
LONDON — The United Kingdom is commemorating World War II codebreaker Alan Turing by making him the new face of the 50-pound note.
With the rainbow flag flying proudly Thursday above the Bank of England, the design of the bank note was unveiled before it is set to be formally issued to the public June 23, Turing’s birthday. The 50-pound note is the most valuable denomination in circulation but is little used during everyday transactions, especially during the coronavirus pandemic as digital exchanges increasingly replaced the use of cash.
The new note, which is laden with high-level security features, completes the bank’s rejig of its stable of paper currencies over the past few years. Turing’s image joins that of Winston Churchill on the 5-pound note, novelist Jane Austen on the 10-pound note and artist J. M. W. Turner on the 20-pound note. All the notes are made from polymer rather than paper, which means they should last longer and remain in better condition through their use.
The new note incorporates two windows and a two-color foil that designers say will make it very difficult to counterfeit. There is also a hologram image which changes between the words “Fifty” and “Pounds” when the note is tilted from side to side, as well as an embedded microchip to pay tribute to Turing’s role in the birth of computers.
Turing was selected as the new face of the 50-pound note in 2019 following a public nomination process, recognition of his pivotal role in breaking Nazi Germany’s Enigma code during World War II. The code had been believed to be unbreakable as the cipher changed continuously. Historians say the cracking of the code may have helped shorten the war by at least two years, potentially saving millions of lives.
The 250,000 or so votes supporting Turing’s nomination also represented a recognition of the discrimination that he faced as a gay man after the war.
“There’s something of the character of a nation in its money, and we are right to consider and celebrate the people on our bank notes,” Bank of England Gov. Andrew Bailey said.
“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.”
During World War II, Turing worked at the secret Bletchley Park code-breaking center, where he helped crack Enigma by creating the “Turing bombe,” a forerunner of modern computers. He also developed the “Turing Test” to measure artificial intelligence.
After the war, he was prosecuted over his relationship with a man in Manchester and given a choice between imprisonment and probation with the condition of undergoing female hormone treatment, which at the time was used as a form of chemical castration.
His conviction led to the removal of his security clearance. He died at age 41 in 1954 after eating an apple laced with cyanide.
Turing received a posthumous apology from the British government in 2009, and a royal pardon in 2013. Four years later, the Turing law, which pardoned gay men with past convictions, was passed.
