Louis Nicolas VauquelinLouis Nicolas Vauquelin (May 16, 1763 - November 14, 1829), was a French pharmacist and chemist. He was born at Saint-Andr-d'Hbertot in Normandy, France. His first acquaintance with chemistry was gained as laboratory assistant to an apothecary in Rouen (1777-1779), and after various vicissitudes he obtained an introduction to AF Fourcroy, in whose laboratory he was an assistant from 1783 to 1791. At first his work appeared as that of his master and patron, then in their joint-names; but in 1790 he began to publish on his own authority, and between that year and 1833 his name is associated with 376 papers. Most of these were simple records of patient and laborious analytical operations, and it is perhaps surprising that among all the substances he analysed he only detected two new elements--beryllium (1798) in beryl and chromium (1797) in a red lead ore from Siberia. He also managed to get liquid ammoniac at the atmospheric pressure. Either together or successively he held the offices of inspector of mines, professor at the School of Mines and at the Polytechnic School, assayer of gold and silver articles, professor of chemistry in the College de France and at the Jardin des Plantes, member of the Council of Industry and Commerce, commissioner on the pharmacy laws, and finally professor of chemistry to the Medical Faculty, to which he succeeded on Fourcroy's death in 1809. His lectures, which were supplemented with practical laboratory teaching, were attended by many chemists who subsequently attained distinction. He died at his birthplace. Among his best known works is "Manuel de l'essayeur" (Manual of the experimental). Vauquelin, Louis Nicolas Vauquelin, Louis Nicolas Vauquelin, Louis Nicolas Vauquelin, Louis Nicolas
