The man credited for saving thousands of lives by breaking the German Enigma Code will feautre on the new £50 bank notes being released into circulation today.

Alan Turing was one of a team who, during the second world war, was stationed at Bletchley Park and targeted with breaking the German code that would change the course of the war.

Despite the efforts that made him a hero, Alan Turing was prosecuted and chemically castrated for homosexual behaviour in 1952. He died of cyanide poisoning 1954,just before his 42 birthday. The coroner's verdict was suicide.

In 2009, following an Internet campaign, British Prime Minister Gordon Brown made an official public apology on behalf of the British government for "the appalling way he was treated".

The Queen granted Turing a posthumous pardon in 2013.
