It is usually accepted that the electron, the first subatomic particle, was discovered by English physicist Joseph John “J.J.” Thomson (1856–1940). Thomson, working at the Cavendish Laboratory in Cambridge, United Kingdom, with his students John Sealy Edward Townsend (1868–1957) and Harold Albert Wilson (1874–1964), performed a series of celebrated experiments between 1897 and 1899 on the cathode rays in a Crookes tube (Figure 1), allowing him to recognize that those rays consisted of very tiny particles, which he called corpuscles (and we call electrons), having a mass-to-electric-charge ratio independent of the emitting material.

Abstract

It is usually accepted that the electron, the first subatomic particle, was discovered by English physicist Joseph John “J.J.” Thomson (1856–1940). Thomson, working at the Cavendish Laboratory in Cambridge, United Kingdom, with his students John Sealy Edward Townsend (1868–1957) and Harold Albert Wilson (1874–1964), performed a series of celebrated experiments between 1897 and 1899 on the cathode rays in a Crookes tube (Figure 1), allowing him to recognize that those rays consisted of very tiny particles, which he called corpuscles (and we call electrons), having a mass-to-electric-charge ratio independent of the emitting material.
