THIS PHYSICIST could be said, in several ways, to be the father of particle physics. He is credited with the first observation/discovery of an elementary particle, for which he received a Nobel Prize in Physics. His son and seven of his students have also been recognized as Nobel laureates. In addition to the above mentioned work (for which he is most famous), he is also credited with demonstrating that non-radioactive elements may have isotopes.
