Karl Heinrich Heydenreich

Karl Heinrich Heydenreich (19 February 1764, Stolpen – 26 April 1801, Burgwerben) was a German philosopher and poet.

Heydenreich was educated at the Thomasschule zu Leipzig and the University of Leipzig. In 1787 he became professor of philosophy at Leipzig. Writing works on Spinoza in the late 1780s, he became increasingly influenced by Immanuel Kant: his Betrachtungen (1790-1) was "the first real example of a Kantian philosophical theology". Forced to give up his professorship in 1797, he died unsalaried.
