George Johnstone Stoney
Irish physicist (–)
George Johnstone Stoney (15 February – 5 July ) was an Irish physicist known for introducing the term electron as the "fundamental unit quantity of electricity".[1]
He initially named it "electrolion" in ,[2] and later named it “electron” in [3][4][5] He published around 75 scientific papers during his lifetime.
Education and employment
[edit]Stoney was born at Oakley Park, near Birr, County Offaly, in the Irish Midlands, the son of George Stoney (–) and Anne Blood (–). The Stoney family is an old-established Anglo-Irish family.[6] He attended Trinity College Dublin, graduating with a B.A. degree in From to he worked as an astronomy assistant to William Parsons, 3rd Earl of Rosse at Birr Castle, County Offaly, where Parsons had built the world's largest telescope, the inch Leviathan of Parsonstown. Simultaneously Stoney continued to study physics and mathematics and was awarded an M.A. by Trinity College Dublin in
From to , Stoney was professor of physics at Queen's College Galway. From to , he was employed as Secretary of the Queen's University of Ireland, an administrative job based in Dublin. In the early s, he moved to the post of superintendent of Civil

The man who ‘invented’ the electron

George Stoney & the heliostat he invented
You could say that the electron, one of nature’s fundamental particles, was invented by the Irish physicist George Johnstone Stoney (). Stoney, born at Oakley Park, Clareen, was the first science professor at the then new university of Queen’s College Galway (now NUI Galway).
A great champion of the metric system, Stoney believed science would benefit from a wise choice of standard units and this prompted him to invent the idea of a standard unit of electricity. Stoney initially called his unit an ‘electrine’ (he later changed it to electron) and he presented his idea to the British Association for the Advancement of Science (BA) at its annual meeting which was held in Belfast. Stoney also calculated that the electron’s charge was Coulombs, based on his analysis of chemical reactions (we now know the charge is 16 times greater, but Stoney’s estimate was reasonable for the time).
Many international scientists liked his idea for an electron, including the German physicist Hermann Helmholtz. In Ireland, Stoney’s nephew and noted scientist George Francis Fitzgerald also championed the concept. When in an English physicist, JJ Thomson, discovered that cathode
