 On the strength of his newfound fame as author of the Letters, Reinhold was invited to be the inaugural occupant of the first professorial chair devoted exclusively to the new Kantian philosophy, and thus he began lecturing at the University of Jena in 1787. First at Jena, and then later at the University of Kiel, Reinhold proved to be an immensely popular and influential teacher, much beloved by his students. (Of the approximately 860 students enrolled in Jena in the Spring Semester of 1794, 600 were enrolled in Reinhold’s three lecture courses.) Indeed, Reinhold was largely responsible for making Jena the center of German philosophy, which it remained for the next several decades.
