- george boole — (person) 1815-11-02 - 2008-05-11 22:58 best known for his contribution to symbolic logic (Boolean Algebra) but also active in other fields such as probability theory, algebra, analysis, and differential equations. He lived, taught, and is buried in Cork City, Ireland. The Boole library at University College Cork is named after him. For centuries philosophers have studied logic, which is orderly and precise reasoning. George Boole argued in 1847 that logic should be allied with mathematics rather than with philosophy. Demonstrating logical principles with mathematical symbols instead of words, he founded symbolic logic, a field of mathematical/philosophical study. In the new discipline he developed, known as Boolean algebra, all objects are divided into separate classes, each with a given property; each class may be described in terms of the presence or absence of the same property. An electrical circuit, for example, is either on or off. Boolean algebra has been applied in the design of binary computer circuits and telephone switching equipment. These devices make use of Boole's two-valued (presence or absence of a property) system. Born in Lincoln, Lincolnshire, UK, George Boole was the son of a tradesman and was largely self-taught. He began teaching at the age of 16 to help support his family. In his spare time he read mathematical journals and soon began to write articles for them. By the age of 29, Boole had received a gold medal for his work from the British Royal Society. His 'Mathematical Analysis of Logic', a pamphlet published in 1847, contained his first statement of the principles of symbolic logic. Two years later he was appointed professor of mathematics at Queen's College in Ireland, even though he had never studied at a university. He died in Ballintemple, Ireland, on 1864-12-08.
