WebHe discovered the electron through his famous cathode ray tube experiment, where he noticed and measured the deflection of the ray (composed of electrons) caused by an electric field. He concluded that there must be a particle with a very small mass but a comparatively large charge, which we now know as the electron. On 22 December 1884, Thomson was appointed Cavendish Professor of Physics at the University of Cambridge. The appointment caused considerable surprise, given that candidates such as Osborne Reynolds or Richard Glazebrook were older and more experienced in laboratory work. Thomson was known for his work as a mathematician, where he was recognized as an exceptional tale…

"WebA cathode made of a wire filament heated red hot by a separate current passing through it would release electrons into the tube by a process called thermionic emission. The first true electronic vacuum tubes, invented in 1904 by John Ambrose Fleming, used this hot cathode technique, and they superseded Crookes tubes. " - How did thomson discovered electrons
