George Boole

Died 8 Dec 1864 at age 49 (born 2 Nov 1815). English mathematician and logician who helped establish modern symbolic logic and an algebra of logic, now called Boolean algebra. By replacing logical operations by symbols, Boole showed that the operations could be manipulated to give logically consistent results. Boole's logical algebra is essentially an algebra of classes, being based on such concepts as complement and union of classes. The study of mathematical or symbolic logic developed mainly from his ideas, and is basic to the design of digital computer circuits. Boolean algebras also find important applications in such diverse fields as topology, measure theory, probability and statistics. Boole also wrote important works on differential equations and other branches of mathematics.
