Theodor Waitz (17 March 1821 – 21 May 1864) was a German psychologist and anthropologist. His research in psychology brought him into touch with anthropology, and he will be best remembered by his monumental work in six volumes, Die Anthropologie der Naturvölker (“The anthropology of peoples that live close to nature”).
Waitz was born at Gotha and educated at Leipzig and Jena. He made philosophy, philology and mathematics his chief studies, and in 1848 he was appointed professor of philosophy in the University of Marburg. He was a severe critic of the philosophy of Fichte, Schelling and Hegel, and considered psychology to be the basis of all philosophy. He died at Marburg.
The first four volumes of his Anthropologie appeared at Leipzig, 1859-1864, the last two were issued posthumously, edited by Gerland. Waitz also published Grundlegung der Psychologie (1846); Lehrbuch der Psychologie als Naturwissenschaft (1849); Allgemeine Pedagogik (1852); Die Indianer Nordamerikas (1864); and a critical edition of the Organon of Aristotle (1844).
