Gordon Welchman established most most critical functions of Bletchley Park, including the key traffic analysis functions known as “Hut 6”.
Gordon Welchman worked closely with Alan Turing, coming up with inspired, improvised solutions to improve the Bombe solution, reducing the time it takes to read enemy messages to hours instead of days. By 1941, Bletchley’s decodes were now changing the course of the war.
Gordon moved to the U.S. and was instrumental in the postwar national security community and in shaping the U.S. intelligence community, especially the NSA. He continued to innovate throughout his life. He established networking ideas and approaches including new methods for command and control of the military and game changing methods of managing battles. He anticipated the Internet and the development of the cloud and cloud computing.
He published a book of his memories, titled The Hut Six Story, but this got him into trouble with NSA and caused him to lose his clearance. That is a very sad day in history, and something I wish we could apologize to him for.
He had made decisive impacts on both World War Two and the Cold War. And really deserves our thanks for what he has done.
