UK unveils new banknote celebrating Alan Turing

Alan Turing is the face of the new £50 note

The Bank of England has unveiled a new banknote

featuring the mathematician who helped Britain win WWII

with his code-breaking skills

(SOUNDBITE) (English) BANK OF ENGLAND GOVERNOR, ANDREW BAILEY, SAYING:"I mean, I think it captures so much of Turing's work in a small space. So you've got, you know, code from one of his... or his pathbreaking work on sort of foundations of computer science and number theory. In the background, you've got actually the sort of the drawings of one of the sort of pioneering computers that he made. I think it's called the ACE machine. And then you've also got probably, of course, the thing that Turing is best known for is his work in the Second World War on the Enigma code cracking and the so-called British bomb machine, and you've got the code from that. So it's really packed in, but in a very nice design - you know, the huge contribution that Turing made."

Turing is believed to have killed himself

after being convicted of gross indecency for being gay

He was given a posthumous royal pardon in 2013

(SOUNDBITE) (English) BANK OF ENGLAND GOVERNOR, ANDREW BAILEY, SAYING:

"Turing was a brilliant mathematician, a brilliant computer scientist, but of course, he was also a gay man and he was a gay man who was treated appallingly."
