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.

John Dalton was a British chemist who developed the modern atomic theory, which suggested that all matter is composed of atoms. J.J. Thomson was a British physicist who discovered the electron and proposed the "plum pudding" model of the atom. Ernest Rutherford was a New Zealand-born physicist who conducted the famous gold foil experiment, leading to the discovery of the atomic nucleus and the development of the nuclear model of the atom.
