Turing was one of the most important and innovative scientists of the 20th century- a genius and a national hero. Situated at Bletchley Park during the Second World War, he designed a machine – the bombe - that could decipher Nazi enigma messages much faster than any other machine before it. It is quite probable that we would have lost the war without him.
Other than his vital effort at Bletchley Park he has come to be known as the father of modern computing science. He lade the foundations for the computer age with his paper, “On Computable Numbers” that led to the creation of the “Turing machine,” a thought process experiment that simulated the logic of a computer algorithm. As Time Magazine put it: "The fact remains that everyone who taps at a keyboard, opening a spreadsheet or a word-processing program, is working on an incarnation of a Turing machine."
Unfortunately, Turing’s life came to a premature and tragic end. In 1952 he was tried and convicted for gross indecency after his homosexual relationship with a 19-year-old Mancunian. His punishment was a choice between jail and probation on the condition of chemical castration via oestrogen. He chose the latter but it ruined his life. He suffered severe side effects and the consensus is that his conviction led to his suicide a year later. The treatment he received from a government he did so much for is despicable; an apology seems not just appropriate but long overdue.
The Spectator has a connection with Alan Turing. Donald Michie was one of Alan Turing’s closest colleagues at Bletchley Park, and his brother; James Michie (the famous poet) wrote for us in his later years as the setter of literary competitions. Under the pseudonym Jaspistos (Donald’s nickname for him) James entertained readers for thirty years with his inexhaustible wit and imagination until his death in 2007. He too would have urged you to sign the petition for Alan Turing: http://petitions.number10.gov.uk/turing/
