Alan Turing, the scientist known for helping crack the Enigma code during the second world war and pioneering the modern computer, has been chosen to appear on the new £50 note.
From the Bank of England’s site:
“Alan Turing provided the theoretical underpinnings for the modern computer. While best known for his work devising code-breaking machines during WWII, Turing played a pivotal role in the development of early computers first at the National Physical Laboratory and later at the University of Manchester. He set the foundations for work on artificial intelligence by considering the question of whether machines could think. Turing was homosexual and was posthumously pardoned by the Queen having been convicted of gross indecency for his relationship with a man. His legacy continues to have an impact on both science and society today.”
Turing was selected from a list of almost 1,000 scientists in a decision that recognised both his role in fending off the threat of German U-boats in the Battle of the Atlantic and the impact of his postwar persecution for homosexuality.
