1911 Encyclopædia Britannica/Tiedemann, Friedrich
TIEDEMANN, FRIEDRICH (1781–1861), German anatomist and physiologist, eldest son of Dietrich Tiedemann (1748-1803), a philosopher and psychologist of considerable repute, was born at Cassel on the 23rd of August 1781. He graduated in medicine at Marburg in 1804, but soon abandoned practice. He devoted himself to the study of natural science, and, betaking himself to Paris, became an ardent follower of Baron Cuvier. On his return to Germany he maintained the claims of patient and sober anatomical research against the prevalent speculations of the school of Lorenz Oken, whose foremost antagonist he was long reckoned. His remarkable studies of the development of the human brain, as correlated with his father's studies on the development of intelligence, deserve mention. He spent most of his life as professor of anatomy and physiology at Heidelberg, a position to which he was appointed in 1816, after having filled the chair of anatomy and zoology for ten years at Landshut, and died at Munich on the 22nd of January 1861.
