Lewis Carroll

Born 27 Jan 1832; died 14 Jan 1898 at age 65. Charles Lutwidge Dodgson, pen-name Lewis Carroll, was an English logician, mathematician, photographer, and novelist, remembered for Alice's Adventures in Wonderland (1865) and its sequel. After graduating from Christ Church College, Oxford in 1854, Dodgson remained there, lecturing on mathematics and writing treatises until 1881. As a mathematician, Dodgson was conservative. He was the author of a fair number of mathematics books, for instance A Syllabus of Plane Algebraical Geometry (1860). His mathematics books have not proved of enduring importance except Euclid and his Modern Rivals (1879) which is of historical interest. As a logician, he was more interested in logic as a game than as an instrument for testing reason.
