Klemens von Metternich
Klemens Metternich was born into the House of Metternich on 15 May 1773 to Franz George Karl Count Metternich-Winneburg zu Beilstein, a diplomat who had passed from the service of the Archbishopric of Trier to that of the Imperial court, and his wife Countess Maria Beatrice Aloisia von Kageneck. He was named in honour of Prince Clemens Wenceslaus of Saxony, the archbishop-elector of Trier and the past employer of his father. He was the eldest son and had one older sister. At the time of his birth the family possessed a ruined keep at Beilstein, a castle at Winneberg, an estate west of Koblenz, and another in Königswart, Bohemia, won during the 17th century. At this time Metternich's father, described as "a boring babbler and chronic liar" by a contemporary, was the Austrian ambassador to the courts of the three Rhenish electors (Trier, Cologne and Mainz). Metternich's education was handled by his mother, heavily influenced by their proximity to France; Metternich spoke French better than German. As a child he went on official visits with his father and, under the direction of Protestant tutor John Frederick Simon, was tutored in academic subjects, swimming, and horsemanship.
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.
