Alan Turing 100th birthday celebrated by Google Doodle

In a doodle celebrating the 100th birthday of Alan Turing, Google creates a functioning Turing machine

June 23, 2012 would have been the 100th birthday of Alan Turing. He was an English logician, computer scientist and mathematican. He invented the Turing machine. This machine played a big part in the coming up of the modern computer.

Turing’s homosexuality resulted in a criminal prosecution 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. He died in 1954, just over two weeks before his 42nd birthday, from cyanide poisoning. An inquest determined it was suicide; his mother and some others believed his death was accidental. On 10 September 2009, following an Internet campaign, British Prime Minister Gordon Brown made an official public apology on behalf of the British government for the way in which Turing was treated after the war.
