Bletchley Park wasn’t built by one man—and history must stop pretending otherwise
For most people, Bletchley Park means one thing: Alan Turing, Enigma, and a single heroic breakthrough.
That story is neat, cinematic—and deeply misleading.
In this episode of History Rage, Paul Bavill is joined by historian, author, and Bletchley Park trustee Sir Dermot Turing to dismantle one of Britain’s most comfortable Second World War myths. What follows is a forensic, passionate unpicking of how thousands of codebreakers—most of them women—have been written out of history.
This is not an attack on Alan Turing. It’s a demand for accuracy.
Sir Dermot explains why Enigma has become a historical obsession, how it eclipses dozens of other vital ciphers, and why reducing Bletchley Park to a single man does a disservice to everyone involved—including Turing himself. From Spanish and Italian diplomatic codes to Japanese military signals, this episode reveals just how broad, complex, and international the intelligence war really was.
Crucially, the conversation exposes how women codebreakers were systematically downgraded by job titles, pay grades, and later historians. Clerical assistants, typists, and “support staff” were in reality performing some of the hardest cryptographic work of the war—often better than the men promoted over them. Figures such as Joan Clarke, Wendy White, Helen Hazelden, Marie Rose Egan, and many others emerge not as footnotes, but as central players.
