Karl Friedrich Heusinger

Karl Friedrich Heusinger (February 28, 1792 - May 5, 1883) was a German pathologist who was a native of Farnroda. He studied medicine in Jena and Marburg, and afterwards was an assistant of Karl Gustav Himly (1772-1837) in Goettingen. In 1813 he became a military doctor in the Prussian Army, and later a professor in Jena (1821), Würzburg (1824) and Marburg (1829–83).

Heusinger was a pioneer in the field of comparative pathology. In 1829 he published an influentual work on physical and psychological anthropology titled Grundriß der physischen und psychischen Anthropologie.
