George Boole (; 2 November 1815 – 8 December 1864) was an English mathematician, educator, philosopher and logician. He worked in the fields of differential equations and algebraic logic, and is best known as the author of ''The Laws of Thought'' (1854) which contains Boolean algebra. Boolean logic is credited with laying the foundations for the information age.〔 Boole maintained that: ==Early life== Boole was born in Lincoln, Lincolnshire, England, the son of John Boole (1779–1848), a shoemaker and Mary Ann Joyce. He had a primary school education, and received lessons from his father, but had little further formal and academic teaching. William Brooke, a bookseller in Lincoln, may have helped him with Latin, which he may also have learned at the school of Thomas Bainbridge. He was self-taught in modern languages.〔Hill, p. 149; (Google Books ).〕 At age 16 Boole became the breadwinner for his parents and three younger siblings, taking up a junior teaching position in Doncaster at Heigham's School.〔Rhees, Rush. (1954) "George Boole as Student and Teacher. By Some of His Friends and Pupils", ''Proceedings of the Royal Irish Academy. Section A: Mathematical and Physical Sciences''. Vol. 57. Royal Irish Academy〕 He taught briefly in Liverpool. Boole participated in the local Mechanics Institute, the Lincoln Mechanics' Institution, which was founded in 1833.〔〔(Society for the History of Astronomy, ''Lincolnshire''. )〕 Edward Bromhead, who knew John Boole through the institution, helped George Boole with mathematics books and he was given the calculus text of Sylvestre François Lacroix by the Rev. George Stevens Dickson of St Swithin's Lincoln. Without a teacher, it took him many years to master calculus.〔 At age 19, Boole successfully established his own school in Lincoln. Four years later he took over Hall's Academy in Waddington, outside Lincoln, following the death of Robert Hall. In 1840 he moved back to Lincoln, where he ran a boarding school.〔 Boole became a prominent local figure, an admirer of John Kaye, the bishop.〔Hill, p. 172 note 2; (Google Books ).〕 He took part in the local campaign for early closing.〔 With E. R. Larken and others he set up a building society in 1847.〔Hill, p. 130 note 1; (Google Books ).〕 He associated also with the Chartist Thomas Cooper, whose wife was a relation.〔Hill, p. 148; (Google Books ).〕 From 1838 onwards Boole was making contacts with sympathetic British academic mathematicians and reading more widely. He studied algebra in the form of symbolic methods, as these were understood at the time, and began to publish research papers.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「George Boole」の詳細全文を読む スポンサード リンク
