“Enigma’s ‘forgotten genius’ . . . [the] story of Alan Turing’s spymaster boss who led the team that cracked Hitler’s WWII codes.” —Daily Mail The Official Secrets Act and the passing of time have prevented the Bletchley Park story from being told by many of its key participants. Here at last is a book that allows some of them to speak for the first time. Gordon Welchman was one of the Park’s most important figures. Like Alan Turing, his pioneering work was fundamental to the success of Bletchley Park and helped pave the way for the birth of the digital age. Yet, his story is largely unknown to many. His book, The Hut Six Story, was the first to reveal not only how they broke the codes, but how it was done on an industrial scale. Its publication created such a stir in GCHQ and the NSA that Welchman was forbidden to discuss the book or his wartime work with the media. In order to finally set the record straight, Bletchley Park historian and tour guide Joel Greenberg has drawn on Welchman’s personal papers and correspondence with wartime colleagues that lay undisturbed in his son’s loft for many years. Packed with fascinating new insights, including Welchman’s thoughts on key Bletchley figures and the development of the bombe machine, this is essential reading for anyone interested in the clandestine activities at Bletchley Park. “A magnificent biography which finally provides recognition to one of Bletchley’s and Britain’s lost heroes.” —Michael Smith “Reveals a man equally as fascinating equally as important as Turing, and tells us even more about what went on in this most secret of establishments during the war years.” —Books Monthly

"Military Communications: From Ancient Times to the 21st Century" is the first comprehensive reference work on the applications of communications technology to military tactics and strategy--a field that is just now coming into its own as a focus of historical study. Ranging from ancient times to the war in Iraq, it offers over 300 alphabetically organized entries covering many methods and modes of transmitting communication through the centuries, as well as key personalities, organizations, strategic applications, and more. "Military Communications" includes examples from armed forces around the world, with a focus on the United States, where many of the most dramatic advances in communications technology and techniques were realized. A number of entries focus on specific battles where communications superiority helped turn the tide, including Tsushima (1905), Tannenberg and the Marne (both 1914), Jutland (1916), and Midway (1942). The book also addresses a range of related topics such as codebreaking, propaganda, and the development of civilian telecommunications.

The revised and extended third edition of this classic reference work on cryptology offers a wealth of new technical and biographical details. The book presupposes only elementary mathematical knowledge. Spiced with exciting, amusing, and sometimes personal accounts from the history of cryptology, it will interest general a broad readership.

"Mr. Pishioneri weaves a great story that brings you through the times when love of family and love of country meant the world to the people of America." Hanging beneath a B-24 Liberator in flight, in 40 to 60 degree weather, bringing his own oxygen and heat with him in this hostile environment; a moving target for enemy fighters, gives one a unique perspective from which to ponder who and what it's all about. The author, a veteran of 35 bombing missions over occupied Europe during World War II, recalls his experiences illuminated by the insight of a Bachelor of Science in American History and 37 1/2 years of teaching Social Studies. A veteran storyteller and talented artist, he weaves his story by chronicling the historical events and personal experiences of his service life between the actual letters he wrote home that were preserved for him by his mother. In Me, Mom and World War II, the reader steps back in time to experience life as the middle child of a large Italian-American family growing up in a small steel town in Western Pennsylvania. The loss of their father, and living through The Great Depression followed by "the emergency" brought on by the bombing of Pearl Harbor forged within them a strength and courage that held them together.
