Johannes Kromayer

Johannes Kromayer (31 July 1859 in Stralsund – 23 September 1934 in Berlin) was a German classical historian. He was an older brother of dermatologist Ernst Kromayer (1862–1933).

He studied classical philology and ancient history at the universities of Jena and Strasbourg, then afterwards worked as a schoolteacher in Thann (1884–88), Metz (1888–93) and Strasbourg (1893–1900). In 1898 he obtained his habilitation for ancient history, and in 1902 became an associate professor at the University of Czernowitz (full professor 1903). From 1913 to 1927 he was a professor of ancient history at the University of Leipzig.

In 1900 he took part in an expedition to Greece in order to study ancient battlefield sites. In 1907/08 he studied ancient battlefields in Italy and North Africa. As a result of his research, he published the four-volume Antike Schlachtfelder ("Ancient Battlefields", 1903–1931).
