             The Manhattan Project was the code name for an effort to create an atomic bomb during World War II. It was named for the Manhattan Engineer District of the U.S. Army Corps of Engineers because most of the early research was done in New York City . Refugee physicists sparked the project soon after German scientists had discovered nuclear fission in 1938. Many American scientists feared that Hitler and the Germans would produce a nuclear bomb; consequently, they contacted Albert Einstein to write a letter to United States President Franklin Delano Roosevelt to help the production of the first nuclear bomb. Roosevelt agreed to assist the scientists and they began the Manhattan Project. The development took place at laboratory at Los Alamos, New Mexico, located on an isolated mesa. The project was to be kept classified under all circumstances. The scientists working at the plant could not even tell their wives a...
