A new sculpture of Alan Turing has been put on display in Paddington, London.
During World War II, Alan Turing, who is known as the father of modern computing, devised the Turing Bombe, a codebreaking device that was used to decipher the Nazi enigma codes, up to 3,000 messages per day. He was also gay, and two years after being convicted of "gross indecency" for being homosexual and sentenced to undergo hormone therapy, he killed himself with a cyanide-laced apple.
Activists and lawmakers are still working to get an official pardon for Turing's conviction from the British government.
The two-dimensional sculpture appeared near St Mary's, Paddington, alongside sculptures of fellow local heroes, famous nurse Mary Seacole and Paddington Bear author Michael Bond.
The sculptures are part of the Portrait Bench series by Sustrans, transport charity, which installs the sculptures, as voted for by local residents. The sculptures are made from Corten steel, the same as the Angel of the North, and will eventually rust to give a more organic look.
