Honoring Betty Webb: Code-Breaking Pioneer at Bletchley Park and the Pentagon

Farewell to a Pioneering Cryptanalyst: Betty Webb at 101

Saying goodbye to Charlotte Elizabeth "Betty" Webb, a cryptanalyst who worked at the legendary Bletchley Park during World War 2, at the ripe age of 101. A trailblazer among a select group of women who defied societal norms by working in this field, Betty shattered preconceived notions that women were uninterested in intellectual work.

Initially applying to the Auxiliary Territorial Service (ATS), Betty's desire to serve her country went beyond just baking sausage rolls, as she put it in a 2012 interview. After volunteering for the ATS, she found herself interviewed at Bletchley Park in 1941 and embarked on a years-long career focused on deciphering German and Japanese encrypted communications, all while keeping the secrets of her work from her 18-year-old parents.

While the extensive secrecy surrounding her work meant that the environment at Bletchley Park knew her only as a 'secretary', historical recognition eventually came her way, with acknowledgements arriving from both the UK and French governments.

Cryptanalysis in the Time of War

Warfare had long relied on encryption, but World War 2 saw a significant escalation in its scale, requiring the development of mechanical and electronic computer systems. Two notable systems used at Bletchley Park were the Bombe and Colossus computers, the former being an electro-mechanical system, and the latter a tube-based machine that took over starting in 1943.

With prompt decryption of intercepted enemy messages crucial due to their time-sensitive nature, the deciphering process required both the systems and the cryptanalysis experts to work tirelessly around the clock. Besides the hands-on decrypting tasks, numerous related tasks, such as registering incoming messages, were essential to maintaining smooth and secure operations.

Upon joining Bletchley Park, Betty's responsibilities included registering incoming messages after being subjected to the contents of the Official Secrets Act, forbidding her from disclosing any details of her work or observations for the risk of severe punishment.

Paraphrasing to Protect Secrets

While Betty's German language skills were commendable thanks to her mother's insistence on self-reliance while traveling on the continent, but the standards for translators at Bletchley were much more stringent, resulting in Betty working in the Japanese section in Block F. After decryption and translation, the texts received paraphrasing treatment to make it less likely for decrypted documents to reveal their origins if they fell into enemy hands.

Gifted at this task, Betty attributed her success to her mother, who encouraged her to tell stories in her own words. Despite the looming threat of the Official Secrets Act, paraphrasing helped those involved maintain their anonymity and forget much of the content they dealt with.

In May 1945, with the conflict in Europe winding down, Betty was relocated to the Pentagon in the U.S. to continue her paraphrasing work on translated Japanese messages. Alone among the ATS staff, she shared a room, and bed, with a girl from Hull.

The Long Shadow of Secrecy

The public revelation of the work at Bletchley Park in 1975 came too late for Betty to share the truth of her war-time work with her parents who had already passed away. Her mother's encouragement to tell stories in her own words undoubtedly played a role in her success as a paraphraser. After years of secrecy, Betty continued to keep her lips sealed even when public speaking opportunities arose in 1990, citing her duty as being more than enough.

Recognized as a Member of the Order of the British Empire (MBE) in 2015 and as a Knight of the Legion of Honour in France in 2021, Betty's contributions to British and French intelligence efforts should never be forgotten. Her pioneering work alongside countless other individuals at Bletchley Park cracked the Enigma encryption and provided a steady stream of intelligence to military command, saving countless lives in the process.

Insights on Women at Bletchley Park

1. Close to 75% of the workers at Bletchley Park were women, challenging societal beliefs by demonstrating their capabilities in previously male-dominated fields.
2. Women took on diverse roles at Bletchley Park, performing tasks like operating the Colossus and Bombe machines, shattering ideas about women's limitations in technical fields.
3. Women's contributions extended beyond clerical and support roles to construction, engineering, and even high-level cryptanalysis. Joan Clarke, for instance, achieved recognition for her work.
4. The experience at Bletchley Park provided women with opportunities for career advancement and recognition, impacting future generations of women in STEM fields.
5. Historically, women's contributions at Bletchley Park have gained increased recognition, contributing to a broader reevaluation of women's roles in history.

After years of serving in a renowned war-time intelligence hub, Betty Webb, a pioneering cryptanalyst, found herself working on deciphering enemy communications in the cutting-edge world of technology, specifically with the tube-based Colossus computer in the sports sector of Block F. Her brilliant paraphrasing skills, honed by her mother, played a crucial role in the success of this mission.
