Stahl

Stahl, GEORG ERNST (1660-1734), German chemist, was a native of Anspach, and studied at Jena, subsequently becoming professor of medicine at Halle in 1694. His knowledge of chemistry was very great, and he made some important discoveries, establishing the phlogistic theory of chemistry, and strongly insisting on the futility of explaining all the phenomena of physical action by mere mechanical laws, and asserting the existence of the soul. He became physician to the King of Prussia in 1716. His most valuable works are the Theoria Medica Vera, Fundamenta Chymiae, and Experimenta.
