Évariste GaloisGalois, Évariste (āvärēstˈ gälwäˈ) [key], 1811–32, French mathematician. At the age of 17 he had evolved original concepts on the theory of algebra. He made important contributions to the theory of equations, the theory of numbers, and the theory of functions and was a pioneer in establishing the theory of groups in algebraic substitutions. Galois was twice imprisoned for his republican sympathies. He was killed in a duel with a political opponent. See I. Stewart, Galois Theory (1973). The Columbia Electronic Encyclopedia, 6th ed.
