Jean-Baptiste Say
1767–1832 · French economist who popularized Adam Smith's ideas in France and gave his name to Say's law of markets.
Jean-Baptiste Say was born in Lyon in 1767 into a Protestant family of cloth merchants and received a commercial education, partly in England. Working for an insurance company in Paris, he read Adam Smith's Wealth of Nations, which shaped his life's work. During the Revolution he edited the journal La Décade philosophique, and in 1799 he was named to the Tribunate. His Treatise on Political Economy (1803) set out a clear system of economics and the law of markets, the idea that production creates the means to buy other goods. When he refused to change the book to support Napoleon's policies, he was removed from office, and he ran a cotton-spinning mill for several years. After Napoleon's fall he published new editions, lectured at the Conservatoire des Arts et Métiers and, from 1831, held the first chair of political economy at the Collège de France. He died in Paris in 1832.
