William Stanley Jevons (1835-1882), English economist and logician, was one of three men to simultaneously advance the so-called "marginal revolution." Jevons' work The Theory of Political Economy (1871), along with similar discoveries made by Carl Menger in Vienna (1871) and by Léon Walras in Switzerland (1874), marked the opening of a new period in the history of economic thought.Jevons studied chemistry and botany at University College, London. Because of the bankruptcy of his father's business in 1847, Jevons left school to take up the position of assayer at the Mint in Sydney, Australia. Returning to England in 1859, he published General Mathematical Theory of Political Economy , and in 1863 Pure Logic , wherein he improved the symbolic logic schema pioneered by George Boole and his teacher Augustus De Morgan. Three years later he was appointed Professor of Logic and Philosophy at Owens College, Manchester, and in 1876 he was glad to exchange the Owens professorship for the professorship of political economy in University College, London.
W. Stanley Jevons (1835-1882) was one of the first great virtuoso scholars in economics. He was author of Theory of Political Economy; The Coal Question; Money and the Mechanism of Exchange; Pure Logic, or the Logic of Quality apart from Quantity; The Principles of Science: A Treatise on Logic and Scientific Method; and Methods of Social Reform and Other Papers.
Warren J. Samuels (1933–2011) was professor emeritus of economics at Michigan State University and is known for his contributions in the areas of the history of economic thought and the methodology of economics.
