Joining the Instrument Section of the Royal Aircraft Establishment at the beginning of World War II, he also made major contributions advising on military strategy and developing operational research, especially protecting the national coastline and U-boats. After the war, he returned to his research at the Manchester University. In 1953 he was appointed Head of the Physics Department of Imperial College of Science and Technology in London, and retired from this position in July of 1963, continuing at the college as professor of physics and pro-rector.

Besides the Nobel Prize,he was awarded the Royal Medal by the Royal Society in 1940 and the American Medal for Merit, for operational research work in connection with the U-boat campaign in 1946. In 1948 he authored the text, “Military and Political Consequences of Atomic Energy.” The American 1949 edition was “Fear, War, and the Bomb.” In 1924 he married Constanza Bayon and the couple had a daughter and a son.
