From University to Court: The Reversal of Stahl's Positions on Gold-Making.

Georg Ernst Stahl, an influential chymical-medical author of the late seventeenth and early eighteenth centuries, first believed in alchemical transmutation and reversed his position over the course of his career. This essay begins by placing Stahl's early teaching in alchemy in a larger background in which German princes and academics shared intense interest in gold-making. Then, tracing Stahl's intellectual development, it shows that he developed an increasing reservation about alchemy, though he remained open to the possibility of transmutation during his tenure at Halle. Finally, this essay shows that Stahl's service to King Friedrich Wilhelm I was an important context for his later public denunciation of alchemy. An analysis of Stahl's career shift from a university professor to a royal physician at court thus sheds light on the reversal of his positions.
