In 1908, Schuchhardt was appointed director of the pre-historic department of the Ethnological Museum of Berlin, part of the Royal Museums in Berlin. He held this post until his retirement in 1925, seeing the museum through the difficult period of World War I, the beginning economic depression in the early Weimar years, and the move to new quarters. At the same time, Schuchhardt conducted a number of highly systematic digs of prehistorical sites around Potsdam, before reaching out after the end of World War I to sites in Lusatia and along the Baltic Sea, including a search for the fabled Slavic fortresses of Vineta and Rethra.Schuchhardt, Karl, Arkona, Rethra, Vineta -- Ortsuntersuchungen und Ausgrabungen.
