1911 Encyclopædia Britannica/Waitz, Theodor
WAITZ, THEODOR (1821-1864), German psychologist and anthropologist, was born at Gotha on the 17th of March 1821. 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. His researches brought him into touch with anthropology, and he will be best remembered by his monumental work in six volumes, Die Anthropologie der Naturvölker. He died on the 21st of May 1864 at Marburg.
In addition to his Anthropologie, the first four volumes of which appeared at Leipzig, 1859-1864, the last two posthumously, he published Grundlegung der Psychologie (1846); Lehrbuch der Psychologie als Naturwissenschaft (1849); Allgemeine Pädagogik (1852); and a critical edition of the Organon of Aristotle (1844).
