Ernest Rutherford

Ernest Rutherford is considered the father of nuclear physics. He lived from 1871-1937, a few years shy of the Manhattan Project that created the atomic bomb. However, his work set the grounds for the creation of atomic weapons. He was the first scientist to determine that it was theoretically possible to split an atom, causing a great amount of energy to be released. Ernest was also known to have a very loud voice. It was said that when he spoke, it was as if he thought he was on stage. Some of his colleagues claimed that Rutherford was not a good experimenter, but that he had more grit and determination than anyone else.
