Chesne, Joseph Du

, called also Quercetanus, lord of La Violette, and physician to the French king, was born at Armagnac, about the middle of the sixteenth century. After having passed a considerable time in Germany, and being admitted to the degree of M. D. at Basle, 1573, he practised his art in Paris, and was made physician to Henry IV. He had made great progress in the study of chemistry, to which he was particularly devoted. The success that attended his practice in this science, excited the spleen of the rest of the physicians, and especially that of Guy Patin, who was continually venting sarcasms and satires against him, but experience has since shewn that Du Chesne was better acquainted with the properties of antimony than Patin and his colleagues. This learned chemist, who is called Du Quesne by Moreri, died at Paris, | at a very advanced age, in 1609. He wrote in French verse, “The Folly of the World,1583, 4to. 2. “The great Mirror of the World,1593, 8vo. He also composed several books of chemistry, which had great reputation once, although they are now forgotten. Haller has given the titles of them, and analyses of the principal of their contents. The most celebrated among them, which passed through the greatest number of editions, is his “Pharmacopoeia Dogmaticorum restituta, pretiosis, selectisque Hermeticorum Floribus illustrata,” Giesse Hess. 1607. This is said to have been recommended by Boerhaave to his pupils. 1
