Paul Grimm (18 August 1907 – 19 November 1993) was a German prehistorian and also a pioneer of Medieval archaeology, especially of the excavation of abandoned villages and castles. Grimm worked on various periods, but mainly in central Germany – the names of two important Neolithic archaeological cultures in the area, the Baalberge group and the Salzmünde group derive from him. His comprehensive excavations at Hohenrode and Tilleda were important milestones in the history of German archaeology.
Grimm was a leading member of the Völkisch movement in the 1920s and 30s and a member of the Nazi Party from 1933. He headed the State Agency for Prehistory and Protohistory in Nazi-occupied Ukraine during World War II. His involvement in the plundering of prehistoric artefacts from the Nazi-occupied territories in Eastern Europe at this time is a matter of controversy. After the war, he lived in East Germany, where he was a professor at Humboldt University of Berlin from 1955 until 1972.
