Sir George Stokes, 1st Baronet
Sir George Gabriel Stokes, 1st Baronet, PRS (/stoʊks/; 13 August 1819 – 1 February 1903), was a mathematician, physicist, politician and theologian. Born in Ireland, Stokes spent all of his career at University of Cambridge, where he served as the Lucasian Professor of Mathematics from 1849 until his death in 1903. Stokes made seminal contributions to fluid dynamics (including the Navier–Stokes equations), optics, and mathematical physics (including the first version of what is now known as Stokes' theorem). He was secretary, then president, of the Royal Society.
