Since 1790, the term Naturwissenschaften occurs in the lecture lists of the University of Jena published in the Allgemeine Literatur‐Zeitung of Jena. Naturwissenschaften is used as a title for lectures previously listed under the headings of Philosophie or Naturgeschichte. The introduction of the concept of Naturwissenschaften is interesting for several reasons: Firstly, at that time it is not the usual label in this context, and one therefore has to ask whether it already implies the connotations that are associated with the (...) modern concept of Naturwissenschaften, i. e. science in the modern sense. Secondly, the lecture lists of the University of Jena give insight into the various changes in the established ordering scheme for academic lectures that lead to the introduction of the term Naturwissenschaften, thus contributing to a better understanding of both the history of this concept and of the development of the university faculties as we know them. A close look at the concept of Naturwissenschaften as it was used around 1800 may, thirdly, help to understand the use made of this concept in philosophy, especially in the philosophy of nature of this period.
