So Kant was passed over. Knutzen never recommended him, and in Knutzen’s letters to Leonard Euler (1707–83), he is not on the list of excellent students (Waschkies 1987: 20). The professor had more regular favorites, such as Johann Weitenkampf (b. 1726) and Friedrich Buck (1722–86), who succeeded to Knutzen’s chair (Pozzo 1993: 283–322; Kuehn 2001b: 23).
