Alan Turing killed himself 60 years ago yesterday.

It's 60 years since Alan Turing killed himself. In his lifetime he was almost unknown to the public yet today he's famous both as a pioneer of computing and as someone lacerated by 1950s attitudes to sexuality. But sisters Barbara Maher and Maria Summerscale can recall him as a family friend.



Alan Turing is commemorated by a statue in Bletchley Park

When Alan Turing died of cyanide poisoning in June 1954 his death was not huge news. The story of how he and colleagues at Bletchley Park had cracked the German Enigma codes was still secret and the Turing name was not yet public property.

In a two-paragraph story reporting his death, the Times described how he had "helped to develop a mechanical brain which he said had solved in a few weeks a problem in higher mathematics that had been a puzzle since the 18th Century". It also noted his work on the Ace "automatic computing machine". A short obituary followed a few days later.

Turing had contributed to a couple of radio programmes on the BBC Third Programme (sadly now lost) but otherwise his wide-ranging work on artificial intelligence and morphology seemed the stuff of specialist journals.

His name emerged from the shadows in 1983 when Andrew Hodges published a well-received biography which inspired the play Breaking the Code. It played in London and on Broadway and was later adapted for TV. The public image of Turing as tortured gay genius was taking shape.
