Winter Talk – ‘How we nearly lost the cipher war against the Germans.’

The nephew of Alan Turing, the father of Enigma, will speak about British communications security – or rather the lack of it – in WW2. Nobody knows about this near-disaster which cost thousands of Allied lives. His book on this subject is called ‘Enigma Traitors’, published in 2023.

There will be a book signing following the talk.

About the Speaker Sir John Dermot Turing is a solicitor and author. He was educated at Sherborne School and King’s College, Cambridge before undertaking a doctorate at New College, Oxford. He then moved into the legal profession. In 2012, the centenary year of his uncle Alan Turing’s birth, Dermot Turing became a trustee of Bletchley Park. He has written several other books on his uncle. ‘X, Y and Z’, published in 2018 covers how Enigma was really broken. Whilst we rightly celebrate what happened at Bletchley Park, their success was built on an international foundation and this is the prequel to the Bletchley story. He has written two further books: one a straight biography (Alan Turing Decoded) and another is more of a myth-buster (Reflections of Alan Turing).
