Joseph Larmor (1857-1942). From Queen's University in Belfast Larmor went to Cambridge, where he bested Thomson in the mathematical exams. After a stint teaching in Galway, Larmor spent most of his career as a Cambridge professor. His elaborately mathematical electrical theory of the late 1890s included the "electron" as a rotational strain (a sort of twist) in the ether. Many physicists envisioned both material particles and electromagnetic forces as structures and strains in that hypothetical fluid.
