The incredible story of the most terrifying weapon ever created. On August 6, 1945, an atomic bomb devastates Hiroshima. Tens of thousands of people are instantly pulverized. And the entire world discovers in horror the existence of the atomic bomb, the first weapon of mass destruction. But in what context, how and by whom could this instrument of death be developed? A true saga of over 450 pages, this graphic novel tells the background and key characters of this historic event, the 75th anniversary of which occurs in 2020. From the uranium mines of Katanga to Japan, passing through Germany, Norway, the USSR and New Mexico, a succession of events so extraordinary as to seem incredible took place. All are here told through their protagonists: be they politicians (Roosevelt, Truman), scientists who have passed into posterity (Einstein, Oppenheimer, Fermi...) or important figures who have remained almost unknown, such as Leó Szilárd (a leading figure in this album, a scientist who moved heaven and earth for the USA to develop the bomb and then did the impossible to ensure that it was never used), Ebb Cade (an African-American worker who was injected with plutonium to study its effects on health) or Leslie Groves (the general who directed the Manhattan project with an iron fist) – without forgetting, of course, the inhabitants and the city of Hiroshima, authentically reconstructed in The Bomb. Extremely well-documented, but above all enthralling, comparable in this to the American and British television miniseries Chernobyl, this work already imposes itself as the reference text on the history of the atomic bomb.
