Although the most memorable effects of the atomic bomb were the mass amounts of death, the development of the atomic bomb has greatly influenced American society and the world.

In August of 1939 Albert Einstein wrote a letter to president Roosevelt to inform him of the potential power of an atomic weapon. It was only then that the United States Government began the serious undertaking known as the “Manhattan Project.” The project was designed to research and create a usable atomic bomb. By 1945, the project had nearly 40 laboratories and factories which employed 200,000 people. That was more than the American Automotive Industry employed at the time.
On July 16, 1945, a brilliant flash changed the world. Thefirst atomic bomb, Fat Boy, was tested in Alamogordo, New Mexico. This was the veryfirst time the world witnessed a nuclear explosion.
Even before the bomb was tested, President Harry Truman had already made the decision to use it on Japan. Although the war was almost over, Truman still decided to use a weapon of such large devastation. There were three main reasons for this.
