Although the bombs helped win World War II the disaster after the bombs were launched left the American society distraught, emotional and changed the society culture. America used the Manhattan Engineer District now called the Manhattan Project as a cover to develop an atomic bomb during World War II. In 1941 the Manhattan Project was developed by President Franklin D. Roosevelt to control nuclear reaction. “The Manhattan Project moved from theory to practice in 1943. The physicist J. Robert Oppenheimer directed the young scientists at Los Alamos in designing a nuclear-fission bomb” (Goldfield 789). “On July 16, 1945 the first atomic bomb was tested in New Mexico now called Ground Zero” (Atomic Bomb Museum). After the major explosion physicists noticed how powerful the bomb was that it could destroy worlds. …show more content…

The top secret project consisted of research and development for building the first nuclear weapon during World War II. The Manhattan Project, spearheaded by Robert Oppenheimer and Leslie R. Groves, originally was just about the atomic bomb; however, Edward Teller and Stanislaw Ulam started to work on a new project introduced by Enrico Fermi. The two together worked to create a higher yield bomb which resulted in the creation of a bomb 450 times more powerful than the previous atom bomb.
