Sir Joseph Larmor FRS FRSE DCL LLD (11 July 1857 – 19 May 1942) was a Northern Irishphysicist and mathematician who made innovations in the understanding of electricity, dynamics, thermodynamics, and the electron theory of matter. His most influential work was Aether and Matter, a theoretical physics book published in 1900.
He was born in Magheragall in County Antrim the son oh Hugh Larmor, a Belfast shopkeeper and his wife, Anna Wright. He was educated at the Royal Belfast Academical Institution, then studied Mathematics at Queen's University Belfast, and St John's College, Cambridge where he was Senior Wrangler. After teaching physics for a few years at Queen's College, Galway, he accepted a lectureship in mathematics at Cambridge in 1885. In 1892 he was elected a Fellow of the Royal Society of London and was made an Honorary Fellow of the Royal Society of Edinburgh in 1910.
In 1903 he was appointed Lucasian Professor of Mathematics at Cambridge, a post he retained until his retirement in 1932. He never married.
Larmor proposed that the aether could be represented as a homogeneous fluid medium which was perfectly incompressible and elastic. Larmor believed the aether was separate from matter. He united Lord Kelvin's model of spinning gyrostats (see Vortex theory of the atom) with this theory.
