			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.

	== ~~See also~~ ==		Thomson's work is linked with the early history of [[Physics:Quantum atoms/electron\|atomic electrons]], [[Physics:Quantum elementary particle\|elementary particles]], and the structure of matter.

'''J. J. Thomson''' (1856-1940) was a British physicist known for experiments with cathode rays that led to the identification of the [[Physics:Quantum electron|electron]] as a subatomic particle. His work helped establish that atoms contain smaller charged constituents rather than being indivisible units.

Thomson received the 1906 Nobel Prize in Physics for investigations of the conduction of electricity by gases. In the Quantum Collection, his name is linked with the historical discovery of the electron and the emergence of subatomic particle physics.
