Nagasaki Atomic Bomb Museum
The atomic bomb was developed by scientists working under the Manhattan Project. The project was granted funding on December 6, 1941, with American leaders aiming for a new invention that would serve as a wartime weapon. The decision to drop an atomic bomb on Japan had been made by 1943, and a shortlist of candidate target cities was in place in 1945. At the time, it was argued that an atomic bombing would bring about a more rapid end to the war. Hiroshima, the first target, was selected to show the power of America's new weapon. The second bombing, of Nagasaki, was intended to demonstrate that the USA had a large arsenal. At 11:02 A.M. local time on August 9, 1945, the atomic bomb, nicknamed Fat Man as its code name by Robert Serber in the United States (after Sydney Greenstreet's character in "The Maltese Falcon") was dropped on Nagasaki, forever changing the city's landscape. A mushroom cloud rose to an altitude of 45,000 feet above the city.
Ralph Austin Bard
On August 6, 1945, the first atomic bomb was dropped on the Japanese city of Hiroshima without the warning that Bard recommended, inflicting approximately 70,000 deaths, including 20,000 Japanese combatants and 20,000 Korean slave laborers. On August 8, the Soviet Union declared war on Japan and launched the invasion of Manchuria which decimated the already-weakening Manchukuo Imperial Army. On August 9, a second bomb was used on the Japanese city of Nagasaki, killing approximately 35,000 people, including 27,778 Japanese munitions employees, 2,000 Korean slave laborers, and 150 Japanese combatants. On August 15, the Emperor announced the surrender of Japan.
