Churchill's Bomb reveals a new aspect of the great Prime Minister's life, so far completely neglected by historians: his relations with his nuclear scientists, and his management of Britain's policy on atomic weapons. Churchill was far more interested in science than he appeared. He made brave efforts to understand the exciting and sinister new world opened up by quantum physics in the 1920s and 30s, and wrote repeatedly about the coming of unimaginably dangerous new explosives. Britain then was the world leader in nuclear research. But when the awful possibility of actually building an atomic bomb raised its head, Churchill made crucial errors that ensured Britain's exclusion from the American-led project to build the bomb. In this original and controversial book, award-winning biographer Graham Farmelo shows a new and less flattering side to the great war leader.
