Many of us have heard about Bletchley Park, Enigma, Alan Turing and the vital work done there to shorten the Second World War. But much less is known about Dilly Knox and his "gels", a bunch of Polish mathematicians from the University of Poznam, and a London Post Office engineer called Tommy Flowers, and the vital role that they all played.

About John McCormick

I've recently retired and one of the things I'm looking forward to is to spend more time speaking and telling stories. I regularly give talks in my local village in the Cotswolds, the fabulous Hook Norton. These talks have ranged from the history of Bletchley Park to the Apollo space programme, to the history of flight to the story of how they solved how to measure Longitude. I'm happy to give these talks to other groups, or to research and then speak on a topic of interest to groups.
