The story of the atom bomb is one of suspense, intrigue, setbacks, triumphs and morality. It started in 1938 when a German chemist split the atom and scientists around the world realized it was possible to build the ultimate weapon. Whoever did it first could control the world. The Germans got a head start as refugee Jewish scientists in America struggled to convince Roosevelt to get involved. But after Pearl Harbor the race was on, and the outcome would change the world forever.
