Tony Sale sadly passed away in August 2011. The tribute below was written at that time.

Tony Sale was born in 1931 and as a teenager was educated at Dulwich College in London. From an early age he showed a remarkable aptitude for engineering and electronics and produced his first robot, George I, from Meccano.

Finances prevented Sale from going to University, so he entered the Royal Air Force instead. He quickly achieved the rank of Flying Officer and at the tender age of 20 was lecturing on radar. He went on to join Marconi’s Research Laboratories in 1952 and five years later joined MI5 where he became Principal Scientific Officer. In the 1960s, 70s and 80s, his fascination with electronics and computers grew and he established several innovative software companies.

Sale’s interest in computer restoration work blossomed in the late 1980s while working at the Science Museum.  In 1989, he helped to set up the Computer Conservation Society as a joint venture between the British Computer Society and the Science Museum.

In 1991, with his wife Margaret and a small group of colleagues, Sale started the ultimately successful campaign to save Bletchley Park for the nation.

Two years later, in recognition of the work carried out at Bletchley Park during World War II, Sale began the Colossus Rebuild Project, a daunting and hugely complex task to recreate the world’s first modern computer. During the war the original Colossus computers had been designed and built to decipher the Lorenz-encrypted messages of the German High Command. The successful decryption of these messages is credited with shortening the war by many months and saving thousands of  lives.

Working with small fragments of information, Sale and his team successfully rebuilt a functioning Colossus, an event that was celebrated in 2007 with the Colossus Cipher Challenge and  the official opening of The National Museum of Computing. Today, the rebuilt Colossus is a centrepiece of the museum.

Andy Clark, Chairman of TNMoC trustees paid tribute to Tony Sale’s achievements at the museum: “Tony’s contributions to The National Museum of Computing have been immense and I am quite sure that without his remarkable talents, enthusiasm, and drive, the museum would not have come into existence. The rebuilding of a functioning Colossus Mk II, Tony’s homage to the wartime codebreakers of the Lorenz cipher at Bletchley Park, is such a remarkable piece of work that it will forever be the model of excellence to which the museum aspires.”

Clark continued: “Tony Sale’s passing is a tremendous loss to us all on a personal and professional basis, but the foundations that he helped to lay are secure. Tony’s energy seemed boundless and, despite being ill in the past weeks, he continued to work diligently: being interviewed by film crews, talking to visitors and laying plans for the refurbishment of the Colossus Gallery. As his wife, Margaret, said to me: ‘Tony’s passing is not the end of his dream’.”

Lin Jones, Operations Manager at TNMoC, said: “Tony Sale was an amazing role model for volunteers at the Museum. Everyone was in awe of his skills and achievements, and he was always ready to give help and advice when asked. He was a huge favourite with visitors and a highlight of their tour. He had a tremendous ability to explain the workings and significance of Colossus on so many different levels. He was able to enthral visitors be they young or old, computer novices or experienced, hardcore cryptographers.”

In recent years, Tony Sale’s achievements have been very widely recognised and amongst other accolades he received honorary doctorates from three universities. In July this year, he was absolutely thrilled to be introduced to Her Majesty The Queen who had specifically asked to see the Colossus rebuild on her visit to Bletchley Park to honour wartime veterans.

Tony Sale was survived for nine years by his wife Margaret, (a tireless worker for Bletchley Park and a long-time supporter and a trustee of TNMoC), three children, seven grandchildren and one great-grandchild.
