Chemist: James Chadwick
Contribution: Proved the Existence of Neutrons
During his experiments studying atomic disintegration, James Chadwick found reason to believe there were neutral charges with mass inside the nucleus of the atom, and in 1932, he was able to prove it. This prepared the way for the fission of Uranium-235 and the creation of the atomic bomb.
