Dear Fellow Members:

The next meeting of the Computer Conservation Society for the 2025/26 season is on Thursday May 21st 2026 at 2.30pm. The subject is a Misread Signals. How History Overlooked Women Codebreakers. Our speaker is an old friend of the CCS, Dermot Turing. It will be a hybrid meeting with the lecture being given at the BCS London meeting room which is at 25 Copthall Avenue, London EC2R 7BP (near Moorgate tube) with an option for interactive participation via Zoom.

The Zoom link for the lecture will be https://us06web.zoom.us/j/87490007950<https://kjwwrjln.r.eu-west-1.awstrack.me/L0/https:%2F%2Fus06web.zoom.us%2Fj%2F87490007950/1/0102019e34fdd7e7-d9adeb79-db63-4af7-b909-662a21f6ab47-000000/T_Z6agbxaWPtZ2iV0zZ6e29TaZY=473>.   A waiting room will be in operation.

About the seminar

Bletchley Park is remembered as a land of male intellectuals who were supported by a staff of women in menial roles, with figures such as Alan Turing, William Tutte and John Tiltman taking centre stage. These are the men who helped sway the course of the war in the Allies’ favour. But, as is often the case in the historical record, this is not the whole story. Women were not just secretaries and assistants: they had serious full-on codebreaking roles. Somehow, when the histories were written, these women were left out. Who were they? What did they achieve? How did they ‘vanish’? In Misread Signals, codebreaking historian Dermot Turing turns his attention to these long-ignored women and puts their contributions back in the spotlight where they belong.

.About the speaker

Dermot Turing is the award-winning author of X, Y and Z – the real story of how Enigma was broken and Enigma Traitors, which reveals the failings of Allied cipher security during World War II. His most recent book is Misread Signals – how History Overlooked Women Codebreakers, which was published in August 2025. He has written numerous other books relating to his famous uncle Alan Turing, codebreaking and computing history. He began writing in 2014 after a career in law, principally at the international law firm Clifford Chance. As well as writing and speaking, Dermot is a trustee of the National Museum of Computing and a Visiting Fellow at Kellogg College, Oxford.
