A new exhibition about the work of World War Two codebreaker Gordon Welchman has opened at Bletchley Park.
The former Cambridge University mathematician worked alongside Alan Turing on the design for a machine to break the Enigma code.
He is also known for setting up the famous 'Hut 6 ' at Bletchley where one million German codes were decrypted.
The family of Bletchley Park codebreaker Alan Turing visited Downing Street today to demand pardons for 49 thousand men who were persecuted for being gay.
Turing killed himself just two years after being convicted for homosexuality. He received a royal pardon in 2013.
A petition has been signed by half a million people including Benedict Cumberbatch who played the mathematician in the Imitation Game.

The family of Bletchley Park codebreaker Alan Turing - who was played on the big screen by Benedict Cumberbatch in The Imitation Game - have been at Downing Street today to demand the Government pardons 49,000 other men persecuted for their homosexuality.
Turing, whose work cracking the German military codes was vital to the British war effort against Nazi Germany, was convicted in 1952 for gross indecency with a 19-year-old man. He was chemically castrated, and two years later died from cyanide poisoning in an apparent suicide.
He was given a posthumous royal pardon in 2013 and campaigners want the Government to pardon all the men convicted under the same outdated law.
Turing's great-nephew, Nevil Hunt, his great-niece, Rachel Barnes, and her son, Thomas, have handed over the petition, which was signed by almost half-a-million people.
Two of the region's scientific breakthroughs are being celebrated on a new set of Royal Mail stamps.
Cambridge scientist Frederick Sangers pioneering technique of DNA sequencing is on the £1.47 stamp.
The code breaking Colossus computer, which was built at Bletchley Park near Milton Keynes, is getting a 1st class stamp.
The stamps form part of the Inventive Britain Special Stamps, issued on 19 February 2015.

A film based on the life of former Bletchley Park codebreaker Alan Turing will be released in cinemas across the country today.
Benedict Cumberbatch stars in the 'The Imitation Game' as the brilliant mathematician who played a key role in cracking the Nazi's Enigma code during the second world war.
Keira Knightley also features in the movie.
An exhibition about the making of a new Hollywood film opens at Bletchley Park in Milton Keynes today.
The Imitation Game, starring Benedict Cumberbatch and Keira Knightley, follows the life and work of code breaker Alan Turing during World War II.
The exhibition features the original sets, costumes and props from the film.
It is due to run for a year.
The perfect way to remember a Second World War codebreaker is with a memorial that has its own hidden secret.
A monument to Bill Tutte has just been unveiled in Newmarket, the Suffolk town in which he grew up.
Like Alan Turing, Bill Tutte helped crack Nazi codes while working at Bletchley Park in Milton Keynes.

It's 75 years since Bletchley Park in Milton Keynes, became a secret base for code-breakers during the Second World War.
The milestone comes with the release of a film, in November, starring Benedict Cumberbatch as Alan Turing. The Bletchley team was credited with bringing an early end to the war by cracking the German's Enigma machine.
Turing was one of thousands working at Bletchley from 1939 - now 80 of those veterans have returned, some for the first time in many years.
