David Ricardo, an English political economist, born of Jewish parentage in London, April 19, 1772, died at Gatcomb park, Gloucestershire, Sept. 11, 1823. He received a commercial education in Holland, and was associated with his father in his business of stock broker. He became a Christian, and in 1793 married against his father's wishes. The partnership was dissolved, but the younger Ricardo in a few years realized a fortune. He studied mathematics, chemistry, and mineralogy, and was one of the promoters of the London geological society. In 1819 he was elected to parliament by the Irish borough of Portarling-ton, which he continued to represent till his death. His first publication was a tract, "The High Price of Bullion a Proof of the Depreciation of Bank Notes" (1809). His principal work is "On the Principles of Political Economy and Taxation" (1817). His works with an account of his life have been collected and edited by J. E. McCulloch (8vo, London, 1846). (See Political Economy).
