 George Johnstone Stoney

George Johnstone Stoney (1826–1911) was an Irish physicist and engineer best known for his contributions to the understanding of atomic theory and for introducing the concept of the electron. He proposed that electricity was made up of discrete units, which he called "electrons" in a paper published in 1874, although the term did not gain popularity until later. Stoney's work laid the groundwork for future developments in atomic physics and largely influenced the field of electrochemistry.
