The three men who discovered the electron, proton, and neutron have a bizarre connection
Not many people have great teachers, and not many people who have great teachers become great themselves. Even less of those who become great through great masters teach great students. Though a bit tongue twisting, that is true. However, there is always someone that comes along to challenge the laws of chance. In this case, three people come along.
James Chadwick, the discoverer of the neutron, also helped produce many technologies during WWII contributing to the creation of the atom bombs, was a student of Ernest Rutherford, who discovered the proton and became known as the father of nuclear physics. Of course, Rutherford didn't gain his knowledge on his own. His teacher was none other than the esteemed J. J. Thompson, who is credited for discovering the electron.
History like this does not repeat itself often. Though they did not study all together, each one, alone or paired with another, helped to further the front lines of science in many different fields.
