Augustus De Morgan (1806-1871) was a British mathematician and logician. He formulated De Morgan's laws and introduced the term mathematical induction. In 1823, at the age of sixteen, he entered Trinity College, Cambridge. He decided to go to the Bar, and took up residence in London, but he much preferred teaching mathematics to reading law. About this time the movement for founding London University took shape. De Morgan, then 22 years of age, was appointed Professor of Mathematics. His introductory lecture On the Study of Mathematics is a discourse upon mental education of permanent value. The best presentation of his view of algebra is found in a volume, entitled Trigonometry and Double Algebra, published in 1849; and his earlier view of formal logic is found in a volume published in 1847. His most distinctive work is styled A Budget of Paradoxes (1872); it originally appeared as letters in the columns of the Athenaeum journal; it was revised and extended by De Morgan in the last years of his life, and was published posthumously by his widow.
