The Enigma Andred Hodges [Book Reviews]

Reports on the life and work of Alan Turing that was presented in this book. Discusses the time in which Alan Turing conducted his work in attempting to crack the enigma code. Perceptions and options of Turing work changed after the publication of this book. Since 1983 a tsunami of information has become available about almost every aspect of the operations of Bletchley Park and its parent organization GCCS (the predecessor of GCHQ, the present-day U.K. signals intelligence and information security organization). This includes the release of the 500+ page “General Report on Tunny” in 2000 (“Tunny” was the code name for an important online German teleprinter encryption device), as well as wartime manuals and technical papers of Turing, Alexander, and others, other archival materials, and memoirs of many people who worked in the different units at Bletchley. The book under review is a reissue of Hodges’s original 1983 biography.
