Joseph John Thomson (1856 - 1940) is credited with discovering the electron. He worked extensively with cathode ray(electrons) tubes and his work led to the development of the mass spectroscope. He developed a model of the atomand, like many brilliant scientists, his model was further refined leading to increasingly better understanding of the structure of the atom. Thomson's student Ernest Rutherford actually proved that Thomson's model of the atom was incorrect.
Thomson then went on to study the nature of positively charged ions.
Thomson was awarded the Nobel Prize for Physics in 1906.
Rutherford was awarded the Nobel Prize for Chemistry 1908 for his work on alpha particles.
JJ Thomson's son was also a winner of the Nobel Prize for Physics in 1937.

J.J. Thomson was a British physicist known for discovering the electron in 1897. He was awarded the Nobel Prize in Physics in 1906 for his work on the conduction of electricity in gases. Thomson's experiments with cathode rays led to the development of the plum pudding model of the atom.
