What had Cathrine to do with the university in Königsberg in 1758? Nothing or nothing? Her husband came in 1762 in power and she had to replace this drunkard about 9 month later also in 1762.
On March 15, 1770, Christoph Langhansen (1691-1770), who had been full professor of mathematics since 1719, died: one of the eight full-time positions in the Faculty of Philosophy could be filled. From the surviving correspondence between Kant, the university, the government and the ministry, it is clear that Kant, with the consent of King Frederick II, had arranged for an exchange of posts, which resulted in the transfer of Friedrich Johann Buck (1722-1786), who had been Professor of Logic and Metaphysics since 1759, to the professorship of mathematics vacated by Langhansen's death and led to Kant's own successful application for the vacant professorship of Logic and Metaphysics.
