Sylvester, James Joseph
Mathematician, born in London, England, UK. He studied at Cambridge but, as a Jew, was disqualified from graduating. He became professor at University College, London (1837), and the University of Virginia (1841--5). Returning to London he worked as an actuary, and was called to the bar in 1850. He then took up academic life again, becoming professor of mathematics at Woolwich (1855--70), at Johns Hopkins University, Baltimore (1877--83), and at Oxford (1883--94). He made important contributions to the theory of invariants and to number theory.
