Georg Ernst StahlDied 14 May 1734 at age 73 (born 21 Oct 1660). German physician and chemist, who developed the phlogiston theory of combustion and of such related biological processes as respiration, fermentation, and decay. Combustible objects, he said, were rich in phlogiston, and during combustion is lost. The remaining ash, now having no phlogiston, could no longer burn.The theory dominated chemical thought for almost a century. He extended the idea to the rusting of metals: metal had phlogiston, rust did not. Air was only indirectly involved in his idea of combustion. It was a carrier of phlogiston, as when charcoal burns phlogiston could be transferred to a metal ore which then converts to metal. At times, Stahl believed in alchemy and animism, though he had rational views on mental disease. |
