Du Pont de Nemours, Pierre Samuel


Born Sept. 14, 1739, in Paris; died Aug. 6, 1817, in Wilmington, USA. French economist and political figure; representative of the physiocratic school.

Du Pont was an active propagandist of the physiocratic ideas of F. Quesnay and R. J. Turgot. In 1767 he published On the Rise and Development of the New Science, in which he gave a very complete and systematic exposition of the teachings of the physiocrats. In 1767 he became editor of the physiocratic journal Ephémérides du citoyen. He published the works of Quesnay in two volumes (1767-68) and of Turgot in nine volumes (1808-11), with valuable commentaries that have not lost their importance. In 1814 he emigrated to the USA.
