  2. J. J. Thomson - Wikipedia

    en.wikipedia.org/wiki/J._J._Thomson

    Thomson made the discovery around the same time that Walter Kaufmann and Emil Wiechert discovered the correct mass to charge ratio of these cathode rays (electrons). [36] The name "electron" was adopted for these particles by the scientific community, mainly due to the advocation by George Francis FitzGerald, Joseph Larmor, and Hendrik Lorentz.

  3. George Johnstone Stoney - Wikipedia

    en.wikipedia.org/wiki/George_Johnstone_Stoney

    George Johnstone Stoney (15 February 1826 – 5 July 1911) was an Irish physicist known for introducing the term electron as the "fundamental unit quantity of electricity". [1] He initially named it "electrolion" in 1881, [2] and later named it “electron” in 1891. [3] [4] [5] He published around 75 scientific papers during his lifetime.

  4. Electron - Wikipedia

    en.wikipedia.org/wiki/Electron

    A 1906 proposal to change to electrion failed because Hendrik Lorentz preferred to keep electron. [19] [20] The word electron is a combination of the words electric and ion. [21] The suffix -on which is now used to designate other subatomic particles, such as a proton or neutron, is in turn derived from electron. [22] [23]

    The discovery of electromagnetic waves in space led to the development of radio in the closing years of the 19th century. The electron as a unit of charge in electrochemistry was posited by G. Johnstone Stoney in 1874, who also coined the term electron in 1894. [135]

  7. Cathode ray - Wikipedia

    en.wikipedia.org/wiki/Cathode_ray

    Cathode rays or electron beams (e-beam) are streams of electrons observed in discharge tubes. If an evacuated glass tube is equipped with two electrodes and a voltage is applied, glass behind the positive electrode is observed to glow, due to electrons emitted from the cathode (the electrode connected to the negative terminal of the voltage ...

    Millikan in 1891. Robert Andrews Millikan was born on March 22, 1868, in Morrison, Illinois. [6] He went to high school in Maquoketa, Iowa and received a bachelor's degree in the classics from Oberlin College in 1891 and his doctorate in physics from Columbia University in 1895 [11] – he was the first to earn a Ph.D. from that department.
