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.
