High Quality Content by WIKIPEDIA articles! Philipp Franz Balthasar von Siebold (February 17, 1796 in Würzburg - October 18, 1866 in Munich) was a German physician. He emerged as the first European to teach Western medicine in Japan. He obtained significance for his study of Japanese flora and fauna that were endemic to the unique biotic island landscape. Born in, Würzburg city, Bishopric of Würzburg into a family of doctors and professors of medicine, von Siebold initially studied medicine at University of Würzburg from November 1815. One of his professors was Franz Xaver Heller (1775-1840), author of the Flora Wirceburgensis (flora of the Grand Duchy of Würzburg, 1810-1811). Ignaz Döllinger (1770-1841), his professor of anatomy and physiology, however, most influenced him. Döllinger was one of the first professors to understand and treat medicine as a natural science. Von Siebold stayed at Dollinger's, where he came in regular contact with other scientists. He read the books of Alexander von Humboldt, a famous naturalist and explorer, which likely raised his desire for travels to far-away, distant lands.
