Eric Raymond discussed this a while back:
The 'Sherlock' star had also been styled appropriately for the time, and wore a grey suit with a matching trench coat, and carried a brown briefcase whilst chatting away to his co-star.
Filming of the highly-anticipated movie began last month, and according to reports it will be a dramatic portrayal of the life and work of Turing.
Following his time of working at the top-secret code-breaking centre, Bletchley Park, during the darkest days of World War II, Turing was later criminally prosecuted for his homosexuality in 1952, when homosexual acts were still illegal in the United Kingdom.
He accepted treatment with female hormones (chemical castration) as an alternative to prison, but died in 1954, just over two weeks before his 42nd birthday, from cyanide poisoning.
The centennial of Alan Turing’s birth brings us the news that Alan Turing probably did not commit suicide by eating a poisoned apple, was not depressed at the time of his death, and that the hormone treatments intended to suppress his homosexual urges had been discontinued a year before he died. I am not in the least surprised by any of this; in fact I have been half-expecting such inversions ever since I began noticing, twenty years or so ago, the increasing mythologization of Turing’s life.I'd watch more TV and films if it didn't seem so full of indoctrination. And quite obvious indoctrination at that.
But the queasiest thing about the myths of Turing-the-exemplar and Turing-the-victim is how they’ve become intertwined. It says no good thing about the year 2012 that Turing’s supposed marginalization by the society of his time has become in many popular accounts a perverse credential for his greatness. In fact he was not marginalized at all – he was a prominent Cambridge don and a hero of his country.who had been awarded the Order of the British Empire. Rather than confront Turing’s homosexuality, the British authorities from the arresting constable on up tried to look the other way and gave every easy out they could; Turing, through some combination of carelessness and self-destructiveness, took none of them.
