Overview The United States detonated two atomic bombs over the Japanese cities of Hiroshima and Nagasaki in Augustkillingpeople—children, women, and men.

In the days following the bombings Japan surrendered. Detonation of these first nuclear bombs signaled arrival of a frightening new Atomic Age. President Franklin Roosevelt created a committee to look into the possibility of developing a nuclear weapon after he received a letter from Nobel Prize laureate Albert Einstein in October In his letter, Einstein warned the president that Nazi Germany was likely already at work on developing a nuclear weapon.

By Augustthe Manhattan Project was underway.

Albert Einstein and J. Einstein warned that the Germans were researching an atomic bomb and suggested that the United States do the same. Oppenheimer was the leading scientist at Los Alamos National Laboratory.

Nuclear materials were processed in reactors located in Oak Ridge, Tennessee and Hanford, Washington. At its peak, the Manhattan Project employedAmericans at thirty-seven facilities across the country. On July 16, the first nuclear bomb was detonated in the early morning darkness at a military test-facility at Alamogordo, New Mexico.
