Wilhelm Gottlieb Tennemann
He was born and educated at Erfurt. In 1788, he became a lecturer on the history of philosophy at the University of Jena. Ten years later he became a professor at the same university, where he remained till 1804. His great work is an eleven-volume history of philosophy ("Geschichte der Philosophie"), which he began at Jena and finished at the University of Marburg, where he was professor of philosophy from 1804 till his death. He was one of the numerous German philosophers who accepted the Kantian theory as a revelation.
