J. J. Thomson (1856-1940) was a British physicist whose cathode-ray experiments led to the identification of the electron as a subatomic particle. His work showed that atoms contain smaller charged constituents and helped move physics beyond the older picture of indivisible atoms.
Electron discovery
In 1897 Thomson measured the charge-to-mass ratio of cathode-ray particles and argued that they were universal constituents of matter. These particles were soon identified with electrons. The result became one of the foundations of modern atomic and particle physics.
Thomson's work is linked with the early history of atomic electrons, elementary particles, and the structure of matter.
