Alan Turing Honored As The Face of the UK's New 50-Pound Bank Note (npr.org) 67

The Bank of England has unveiled the new 50-pound note featuring mathematician and computer science pioneer Alan Turing, who helped the Allies win World War II with his code-breaking prowess but died an outcast after facing government persecution over his homosexuality. NPR reports: The bank revealed the note's design and features -- which include a number of clever visual references to Turing's work -- on Thursday, nearly two years after first announcing that it would honor Turing. The banknote will officially enter circulation on June 23, Turing's birthday. Andrew Bailey, the governor of the Bank of England, noted in prepared remarks that Turing is arguably best known for his code-breaking work, which historians credit with shortening World War II by about two years and saving millions of lives. But far beyond that, he said, Turing's pioneering work in computing and artificial intelligence "has had an enormous impact on how we all live today."

Instead of paper, the new note is made from polymer, which is longer-lasting and harder to counterfeit. It completes the bank's "family" of polymer banknotes, Bailey said, joining the Winston Churchill 5-pound, Jane Austen 10-pound and J.M.W. Turner 20-pound. The note itself features an image of Turing and his signature as it appeared in a 1947 visitor's sign-in book on display at Bletchley Park Trust, where he worked during the war. It includes a quotation, taken from a 1949 interview in which Turing was speaking about his ground-breaking Pilot ACE machine, one of the world's first computers: "This is only a foretaste of what is to come and only the shadow of what is going to be."

Symbolic designs on the note include a mathematical table and formulae from Turing's 1936 paper "On Computable Numbers, with an application to the Entscheidungsproblem," technical drawings of the British Bombe code-breaking machine and ticker tape depicting his birth date in binary code. A sunflower-shaped foil patch, containing the initials "AT, "represents Turing's work in morphogenetics, a branch of developmental biology focused on the algorithms behind patterns occurring in nature. It's another scientific field for which Turing helped lay the groundwork, Bailey noted.

    70 years ago Turing was booed and convicted for indecency. Better live in the right time.
    • Yes, he was convicted and inhumanely punished which led to his suicide.

      This despite the fact that he was a genius whose work changed the world and a war hero whose work saved it.

      His accomplishments outshined his fame then, and continue to outshine the fame of most famous people ever since.

        Exactly. In computer science circles he's up there with Babbage as basically the two fathers of modern digital computing. But while Babbage's differential machine was an unrealized curiosity (due to the limits of machining capabilities in the 19th century), Turing's contributions to modern computing are direct and discernible. Oh, and that he's as responsible for beating Germany as just about anyone can be said to be, he gets that extraordinary honor. And that his genius and contributions were insufficient for the British courts to do anything but treat him in a horrifying and undignified manner is a dark stain on Britain. They treated one of their heroes, and one of the great minds of the 20th century, like some depraved monster.

          Turing's work was so secret that when he was prosecuted and convicted, he was just an academic as far as the public and press were concerned. Very few people would have known of his contribution and wouldn't dared have spoken publicly about it. Many of the workers at Bletchley Park went to their graves and never talked of anything they did.

          His work and the whole decoding effort at Bletchley Park only became public knowledge in the late 70s and early 80s. The Government classified it as very high security material because the work done in WW2 continued against the Soviet Union and other countries.

          Yes he saw shamefully treated and the law in those days was unjust but he wasn't a public hero then.

          • The landmark work on computation and the Turing machine and programs that could not be written was all published in 1930s. That is how I first learned about Turing.

            He was also one of several geniuses that worked on Enigma, but he was not the most important.

            The reason that he is on the note is because he was gay. How times have changed, in this case probably for the better.

            Yes, and if Britain's government had any common decency at the time, the old boy network would have been invoked and the prosecutor taken aside and told very firmly to leave him alone. He didn't have to know why. He just had to be told. And it's very reasonable to demand such. Britain's government is famous for its old boy network. That's what boarding schools do for you.

              Not quite as simple as that. Then the Police ran the prosecutions and any attempt from on high to stop it would have been more likely to backfire with a journalist tipped off in a pub. The only way to stop a newspaper publishing material is a "D-Notice [wikipedia.org]' which is only used for matters of National Security and sparingly as it's a semi-voluntary code. Do not underestimate the power of the press in the UK who even then were no fans of the Establishment.

        To assuage the guilt of those that did the persecuting. What did it do for a dead Alan Turning, NOTHING. I got an opinion on posthumous awards, SHOVE THEM UP YOUR FUCKING COLLECTIVE ARSES.

        Do something right when they are alive, after they are dead, to assuage guilt, what a waste of fucking time, as far as that person is concerned.

        The country and government that shat all over the dude in life, is now trying to claim greatness from their victim.

        • The alternative is what then? Continue to perpetuate dehumanizing rhetoric and/or bury his existance completly? No one is justifing the heanous treatment of the man by putting him on on bank note, only keeping his memory and contribution alive in such a way that it may inspire future computer scientists.
        • What are you proposing? We build a time machine? Dig up Turing's corpse and resurrect him?

          We can't change what our forbears did. Those who did the persecuting are long dead as is the victim.

          Recognising the work of Turing, a gay man, now will help those alive today who continue to experience unfair treatment due to sexual orientation.

          It is accepted that Turing's treatment was unfair and unjust by today's standards but there is nothing that can be done other than honour and remember him.

        Yes, he was convicted and inhumanely punished which led to his suicide.

        The "suicide" story is disputed. The police ruled it suicide at the time because of the presence of cyanide. But Turing had been experimenting with electroplating in his room using potassium cyanide. Given that he was a mathematician - not a chemist - it's likely he accidentally poisoned himself by inhaling cyanide vapours from his own experiments.

        At best we can say the suicide story is possible but unproven. And I

          Hmmm, That sounds ... dubious. You'd need to get on the order of 0.2g of hydrogen cyanide into the lungs. 0.0074 moles. About 0.2 litres of neat cyanide gas (at NTP) that needs to be generated, then get into the lungs. That's quite a lot. Even a fairly incompetent chemist will see that amount of bubbling. And the smell is apparently quite strong, too. I routinely use out-of-date calibration ampoules of highly toxic hyd
