The landscape of seventeenth-century chemistry is complex, and it is impossible to find in it either a clear-cut distinction between alchemy and chemistry or a sort of simple identification of the two. The seventeenth-century cultural context contained a rich variety of "chemical" discourses with arguments ranging from specific experiments to the justification of the validity of chemistry and its novelty in terms of its extraordinary antiquity. On the basis of an analysis of the works by O. Borch, J.J. Glauber, and (...) J. J. Becher, this paper tries to demonstrate that a historical reconstruction of "chemistry" must consider these different levels of the chemical debate. Only then will it be possible to appreciate the outstanding role played by G.E. Stahl in founding modern chemistry. The paper argues in favor of a contextualization of the historical research on seventeenth-century chemistry. (shrink)

Georg Ernst Stahl is one of the most outstanding physicians and naturalists of the so‐called Frühaufklärung in Germany. His scientific, philosophical, and ideological influence was deep and widespread in almost all the German states. As a professor at the University of Halle, the First Royal Physician in Berlin, and president of the Higher Medical Board of Prussia, he created a Stahlian school of medicine and chemistry, shaping some branches of medical thought, as well as of pure and applied chemistry. In (...) the history of chemistry his name is generally associated with the theory of phlogiston, and in the history of medicine he is described as a vitalist. (shrink)
