George Boole, 1815 - 1864
No, a Boolean operator is not someone from an obscure foreign country who's a day trader of stocks on the Web! Boolean operators are the connectors AND, OR, and NOT that can be used in keyword searches.
George Boole was a 19th century Englishman, the son of a poor shoemaker. A self-taught mathematician, Boole was offered a university position solely on the basis of his publications. His work on mathematical logic, algebra, and the binary systems of 0 and 1, had a unique influence upon the development of computers. On a personal note, he married Mary Everest, the niece of the man for whom Mt. Everest is named. The couple had five daughters who variously excelled in mathematics, chemistry, and the fine arts.
