HistoryNamed after Friedrich Gustav Jakob Henle (1809-1885), who was a German physician, pathologist, and anatomist and received his medical doctorate from the University of Bonn in 1832. He spent his early career as a prosector for Johannes Müller in Berlin where he published furiously on numerous facets of human and animal anatomy and physiology. He then went on to become the chair of anatomy at the University of Zurich, where he became one of the early adopters and advocates for the study of pathophysiology as a single distinct discipline. He also set the early argument for the germ theory in an essay entitled “On Miasma and Contagia”. His life’s work culminated in the publishing of the Handbook of Systematic Human Anatomy in 1855, which was the most complete and comprehensive work at that time.
