Johannes Nikolaus Tetens
He has been called the "German Locke," on the basis of a comparison of his major work "Philosophische Versuche über die menschliche Natur und ihre Entwickelung" (1777) with the work of John Locke. He is considered to have been an influence on Immanuel Kant.
Tetens was born 1736 in Tetenbüll/Tetenbøl in the Danish Duchy of Schleswig. He studied mathematics and physics at the University of Rostock and the University of Copenhagen. He acquired in MA in 1759 and his PhD in 1760. From 1760 to 1765, he taught philosophy and physics ("natural philosophy" at that time) at the (in Bützow, Mecklenburg-Western Pomerania). During this decade, he wrote many treatises on various subjects, ranging from the color of the sky to the existence of God through the origins of languages (see e. g. references in Johann Christian Poggendorff, 1863). After this polygraphic formation period, Tetens goes back to more fundamental enquiries: after having read David Hume's work, he popularized it throughout the German-speaking world. Tetens is therefore supposed to have introduced Immanuel Kant to phenomenalistic thought and to the empiricism / transcendence dualism.
