Ronald Koorm explores the complex relationship between Bletchley Park and its support codebreaking outstations, the background to the Enigma encoding machine, and how Eastcote became the largest codebreaking outstation during the war. He analyses the development of improvements on Alan Turing’s Bombe machine, the contribution of the WRNS (Wrens) in operating the machines, and some of the social history showing how those Wrens from varying social backgrounds displayed outstanding teamwork under immense pressure at the codebreaking sites.
Post-war, Eastcote became GCHQ prior to moving to Cheltenham, and there were multiple uses of the site, including Cold War counter-intelligence operations. The author explores the link between Alan Turing and others in terms of the quest for Artificial Intelligence, and how talented individuals during the war helped shape the future. Backing Bletchley includes previously unpublished diagrams, charts and illustrations of the story of the outstations, which shed further light on the extraordinary historic events that occurred at them.
Ronald Koorm ran his own surveying and design consultancy for many years. He has lectured in various subjects including codebreaking and outstations during the Second World War. His research over recent years has been on Eastcote, codebreaking and the development to GCHQ. His diary for talks on the subject for 2020‒21 is almost full. He is an active member of the Access Association, He has written articles for RICS and for other journals and blogs for bodies such as the Construction Industry Council.
