The Bletchley Park memoir of Lord ASA Briggs will be one of the most important documents to be published in 2010. Lord Briggs has long been regarded as one of Britains most important historians. He has never however written about his time at Bletchley Park. The publication which will coincide with Lord Briggs 90th birthday is a meticulously researched account of life in Hut Six written by a codebreaker who worked there for five years alongside Alan Turing & Gordon Welchman. In addition to discussing the progress of the Alliescode-breaking efforts & their impact on the war Lord Briggs considers what the Germans knew about Bletchley & how they reacted to revelatory memoirs about the Enigma machine which were not published until the 1970s. Briggs himself did not tell his wife about his wartime career until the 1970s & his parents died without ever knowing their sons contribution to the wartime effort. The book will be launched at Bletchley in May 2011 in the presence of other Hut 6 veterans & part of the proceeds will be donated to the fund to restore Hut 6 to its former glory.
