Physicist and Manhattan Project Leader.

J.Robert   Oppenheimer was a brilliant physicist who made significant contributions to the field of theoretical physics before his involvement with the Manhattan Project. As the leader of the project, he played a critical role in developing the first atomic bomb, which was used to devastating effect in Japan. Oppenheimer later became a vocal opponent of nuclear weapons, advocating for international control of atomic energy. Despite his controversial legacy, he remains one of the most important figures in the history of modern science.
