Gay mathematician and computer scientist Alan Turing is the Greatest Person of the 20th Century, according to a public TV vote held by the BBC.
Turing was responsible for cracking the Germans’ secret Enigma code during the Second World War.
In doing so, it is estimated that he saved tens of thousands of lives, and shortened the War by four years.
Turing was gay and when he was prosecuted in 1952 for homosexuality, which was illegal at that time, he opted to undertake chemical castration rather than imprisonment.
Two years later in 1954, he died of cyanide poisoning, which an inquest ruled was suicide.
In 2009 the then UK Prime Minister Gordon Brown issued a pubic apology for Turing’s treatment at the hands of the British government.
In 2013 he was also granted a posthumous pardon.
In the BBC show Icons: The Greatest Person of the 20th Century, Turing’s case was presented by TV presenter Chris Packham.
Other figures nominated included Nelson Mandela, Mohammed Ali and David Bowie.
