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.

Georg Ernst Stahl 是 17 世纪末和 18 世纪初一位有影响力的化学医学作家，他首先相信炼金术嬗变，并在他的职业生涯中改变了自己的立场。本文首先将斯塔尔早期的炼金术教学置于一个更大的背景中，在这个背景下，德国王子和学者对黄金制造有着浓厚的兴趣。然后，追溯斯塔尔的智力发展，它表明他对炼金术越来越持保留态度，尽管他在哈雷任职期间仍然对嬗变的可能性持开放态度。最后，这篇文章表明斯塔尔对弗里德里希·威廉一世国王的服务是他后来公开谴责炼金术的重要背景。
