Friedrich Martius

Friedrich Martius (7 September 1850, Erxleben – 1 October 1923, Rostock) was a German internist who was one of the pioneers of constitutional thought in medicine. He was the father of philosopher Hedwig Conrad-Martius (1888–1966).

He studied medicine at the Pépinière in Berlin, obtaining his doctorate in 1874. Following graduation, he served as a military doctor, and afterwards worked as an assistant in the clinic of Carl Gerhardt in Berlin. In 1887 he received his habilitation, and later was appointed personal physician to Frederick Francis III, Grand Duke of Mecklenburg-Schwerin. In 1891 he relocated to the University of Rostock as an associate professor and director of the medical clinic. In 1899 he attained a full professorship at Rostock.
