About eight years ago, after a career in international IT and Management Consultancy, Mike became a volunteer at Bletchley Park, having attended as a visitor for perhaps ten years previously as a visitor.  Mike serves as a volunteer Guide at the BP heritage museum and also demonstrates the Turing-Welchman Bombe and Enigma codebreaking at the National Museum of Computing. In 2024, Mike Barbakoff entertained us with his presentation about The Women of Bletchley Park. He now presents “Codebreaking against the Land of the Rising Sun”. This talk embraces the inception of the UK/USA Special Relationship and highlights the Signals Intelligence activities of the United Kingdom and United States against Japan in the Second World War.  It covers the efforts of Bletchley Park and its overseas outstations as well as the enormous contribution of the Unites States Navy and Army, Australia and New Zealand SIGINT operations. Failures such as Pearl Harbor and successes such as the Battle of Midway are used to illustrate the effectiveness of Signals Intelligence No fee to be paid Contact: Groups via this link (select addressee: Groups) The meeting will be hybrid, if you wish to participate on Zoom, use the link that will be supplied in the Group News closer to the date.
