Crowdfunded Bombe gallery opened

On Saturday 23 June 2018, two veteran Bombe operators opened the new Bombe Gallery at The National Museum of Computing on Bletchley Park, just three months after the completion of a successful £50,000 Crowdfunder to finance the new display.

The Turing-Welchman Bombe automated the deciphering of Enigma-encrypted messages during the Second World War. As a tribute to the codebreakers, a team led by John Harper reconstructed the machine in 2007 and in April 2018, the Bombe was moved to The National Museum of Computing, close to the reconstruction of the Colossus computer that accelerated the breaking of Lorenz-encrypted messages of German High Command. Together these machines are credited with shortening the war by two years, saving countless lives.

At the opening of the new gallery TNMOC deputy chair Tim Reynolds said, “We now have working reconstructions of two of the most important machines of the Second World War under one roof thanks to the generosity of our Crowdfunder donors. In their hey-day, these machines changed the world and today their significance is undiminished. Visiting student groups and the general public can watch in awe and be inspired by these historic working machines that paved the way to our digital world.”

Sworn to secrecy, the operators of the Bombes had little knowledge of the significance of their work until decades after the war.

At the gallery opening, WRNS (Women’s Royal Naval Service) and Bombe operator Ruth Bourne recalled, “We were told that we would be breaking German codes, but we never knew anything about it breaking Enigma! It was only years later that I read the books and discovered what I had been doing! During the war we were told never to tell anyone what we had seen or heard.”

Fellow WRNS and Bombe operator Jean Valentine said, “When I joined the Navy they asked about interests and hobbies. I told them I liked puzzles and crosswords and they said: we know where you will be going, but we don’t know what you will be doing there. They will tell you when you get there.”

At the opening of the gallery, each WRNS spoke of their vivid memories of the requirement for accuracy and concentration when using the Bombe, of the long shifts, repetitive work and the excitement of using the ‘red phone’ to tell army or navy personnel of a potentially significant message that they thought they could decrypt with the Bombe – though they never learned the contents of those messages.

At the opening, the WRNs were also able to meet and exchange notes for the first time with Margaret Bullen, who wired Colossus computers as they arrived on Bletchley Park.

Notes To Editors

About the Turing-Welchman Bombe reconstruction

The Turing-Welchman Bombe was the electro-mechanical device designed by Alan Turing and Gordon Welchman, based on a Polish concept, to automate the deciphering of Enigma-encrypted messages during the Second World War.

In the early 1990s John Harper, a retired engineer, was inspired to recruit a team to reconstruct a Bombe machine as a tribute to the wartime code-breakers at Bletchley Park. The reconstructed Bombe was completed and officially launched in 2007. The reconstruction replicates the standard British Bombe that contained 36 Enigma equivalents, each with three drums wired to produce the same enciphering effect as the Enigma cipher machine motors.

The reconstructed Bombe was moved to The National Museum of Computing at the end of April 2018 following an appeal for funds to the general public through a Crowdfunder. The new Gallery was rapidly equipped and opened officially on 23 June 2018.

About The National Museum of Computing

The National Museum of Computing, located on Bletchley Park in Block H, one of England’s ‘irreplaceable places’, is an independent charity housing the world's largest collection of functional historic computers, including reconstructions of the wartime code-breaking Colossus and the Bombe, and the WITCH, the world's oldest working digital computer. The Museum enables visitors to follow the development of computing from the ultra-secret pioneering efforts of the 1940s through the large systems and mainframes of the 1950s, 60s and 70s, and the rise of personal computing in the 1980s and beyond.

The Museum runs a highly successful Learning Programme for schools and colleges and promotes introductions to computer coding amongst young people to inspire the next generation of computer scientists and engineers.

Sponsors of the Museum have included Bletchley Park Science and Innovation Centre, Fujitsu, InsightSoftware.com, Paessler, Sophos, Lenovo, Bloomberg, Ocado Technology, Ceravision, CreateOnline, 4Links, Google UK, IBM, NPL, HP Labs, FUZE and BCS.

The whole Museum is open to the public from 12 noon - 5 pm on Thursdays, Saturdays and Sundays, spring and summer Bank Holidays. During long school holidays, there are additional opening days. The Colossus and Tunny galleries are open daily. Public and private Guided Tours are available and bookable online – see the website for details. Educational and corporate group visits are available by prior arrangement.
