Code breaker's manuscript sells for USD1 million


NEW YORK - A 56-page handwritten notebook that belonged to World War 2 Nazi code breaker and computer pioneer Alan Turing, played by actor Benedict Cumberbatch in the film "The Imitation Game," sold for more than USD1 million at an auction in New York, Bonhams said on Monday.

Turing, a British mathematical genius, led a team of cryptographers who cracked the wartime Enigma code, which the Germans had considered unbreakable. Their work is credited with hastening the end of the war and saving lives.

Cassandra Hatton, senior specialist in Bonhams' fine books and manuscripts department, said the result of the auction as a testament to Turing's legacy. Bonhams declined to name the buyer.

"It reflects his importance in history. I think he is someone who merits further study, and I hope this contributes to increased interest in him and his work," she said in an interview.

The auction also reaffirms a growing interest in scientific material, the history of computers, space, exploration and early science, she added.

Part of the proceeds from the sale will go to an unspecified charity.

The notebook, which had never been seen in public, is considered the only existing, extensive manuscript by Turing. It dates back to 1942 and was left to his friend Robin Gandy. In it Turing worked on mathematical formulas and the basics of computer science, giving insights into the workings of his brilliant mind.

Gandy added his own notes between the pages of Turing's musings and kept the notebook hidden until his death.

Turing, a homosexual, never received credit for his groundbreaking work during the war. He committed suicide in 1954 at the age of 41 while receiving hormone treatment. It was an alternative to imprisonment after he was charged with gross indecency in 1952 for having sex with a man. Homosexual sex was a crime at that time in Britain.

Sixty years after his death Turing received a rare, royal pardon by Queen Elizabeth for his gay conviction.

Cumberbatch received a best actor Academy Award nomination for his portrayal of Turing in the film, which won an Oscar for best adapted screenplay. The film is based on the book, "Alan Turing: The Enigma," by Andrew Hodges.

"This notebook shines extra light on how, even when he was enmeshed in great world events, he remained committed to free-thinking work in pure mathematics," Hodges said in a statement.

Britain pardons gay 'father of computing' Alan Turing


LONDON - Britain on Tuesday granted a posthumous pardon to Alan Turing, the World War II code-breaking hero who committed suicide after he was convicted of the then crime of homosexuality.

Turing is often hailed as a father of modern computing and he played a pivotal role in breaking Germany's "Enigma" code, an effort that some historians say brought an early end to World War II.

He died in 1954 after eating an apple laced with cyanide, two years after he was sentenced to chemical castration for the "gross indecency" of homosexuality. A coroner ruled that Turing committed suicide, though this has since been questioned.

Queen Elizabeth II has now pardoned Turing for "a sentence we would now consider unjust and discriminatory", justice minister Chris Grayling said.

Homosexuality was decriminalised in Britain in 1967.

"A pardon from the queen is a fitting tribute to an exceptional man," Grayling said.

Prime Minister David Cameron said the code-breaker's work had saved "countless lives".

"Alan Turing was a remarkable man who played a key role in saving this country in World War II by cracking the German Enigma code," Cameron said.

"He also left a remarkable national legacy through his substantial scientific achievements, often being referred to as the father of modern computing."

The Enigma code was used to encrypt communications between German U-boats in the North Atlantic ocean. Turing's efforts to break it were virtually unknown to the public at the time of his death, as his work was kept secret until 1974.

Turing also published pioneering work on early computers, writing in a 1936 paper of a "universal Turing machine".

Having told people he was trying to "build a brain", his theory was the first to consider feeding programmes into a machine as data, allowing a single machine to perform the functions of many -- just like today's computers.

He lost his job at Britain's electronic eavesdropping agency GCHQ after he was convicted and poisoned himself with cyanide at the age of 41.

A GCHQ spokesperson on Tuesday said the agency was "delighted about the pardon".

The pardon is a victory for supporters, including leading scientists such as Britain's Stephen Hawking, who have long campaigned to clear Turing's name.

Britain's prime minister in 2009, Gordon Brown, issued a posthumous apology to the code-breaker, saying he had been treated "terribly".

But the government rejected a call to grant an official pardon last year on the grounds that Turing was properly convicted of what was then a criminal offence.

More than 37,000 people signed an online petition last year calling for a pardon.

Pardons are usually only granted in Britain when the person is innocent of the offence and when it is requested by someone with a vested interest, such as a family member.

Turing's pardon is extremely rare in that it has been granted despite neither of these conditions being met.
