The first full-scale biography of the "father of the atomic bomb," the brilliant, charismatic physicist who led the effort to capture the fire of the sun for his country in time of war. After Hiroshima, he became the most famous scientist of his generation--an icon of modern man confronting the consequences of scientific progress. He created a radical proposal to place international controls over atomic materials, opposed the development of the hydrogen bomb and criticized the Air Force's plans to fight a nuclear war. In the hysteria of the early 1950s, his ideas were anathema to powerful advocates of a massive nuclear buildup, and people such as Edward Teller and FBI director J. Edgar Hoover worked behind the scenes to obtain a finding that he could not be trusted with America's nuclear secrets. This book is both biography and history, significant to our understanding of our recent past--and of our choices for the future.
