On August 6, 1945, at 8:15 in the morning, an explosive charge of more than 15 kilotons fell on the city of Hiroshima. Tens of thousands of people were pulverized, and everything within four square miles was instantly destroyed. A deluge of flames and ash had just caused Japan's greatest trauma and changed the course of modern warfare and life on Earth forever. The world was horrified by the existence of the bomb-the first weapon of mass destruction. But how could such an appalling tool be invented? In The Bomb, Didier Alcante, Laurent-Frédéric Bollée, and Denis Rodier have created an exhaustive and definitive work of nonfiction that details the stories of the unsung players as well as the remarkable men and women who are at the crux of its history and the events that followed.
