Nicolas Lemery, a French chemist, born in Rouen, Nov. 17, 1645, died in Paris, June 19, 1715. His chemical lectures in Montpellier, and subsequently in Paris, were very popular. He stripped the science of most of the prevailing charlatanry, and Fontenelle and Voltaire expressed the highest regard for his attainments. His Cours de cliimie (Paris, 1675) passed through more than 30 editions, the best being by Baron (1756), was translated into many languages, and was the highest authority for nearly a century. On account of Lemery being a Protestant, he was deprived of his license in 1681, and after declining an offer from the elector of Brandenburg to teach chemistry in Berlin, he went to England in 1683, and was favorably received by Charles II., but soon resumed his practice in Paris. The revocation of the edict of Nantes threatening to deprive him of all means of subsistence, he united with the Catholic church in 1686. In 1699 he was admitted to the academy of sciences as associate member, and afterward as pensioner.

His principal works, besides his lectures on chemistry, are: Pharmacopee universelle (Paris, 1697; 8th ed., 1763); Traite universel des drogues simples (1698, and several later editions); and Nouveau recueildes secrets et curiosites les plus rares (2 vols., Amsterdam, 1709). - His son Louis (1677-1743) excelled as a physician and writer, as also his son Jacques, known as Le-mery jeune (1678-1721).
