Albert Einstein and Robert Oppenheimer did not invent the atomic bomb; rather they were involved in the scientific and theoretical developments that led to its creation. The atomic bomb was developed as part of the Manhattan Project during World War II in response to fears that Nazi Germany was working on similar weapons.
