Astrid Friis (1893–1966) was a Danish historian. In 1945, she was appointed professor of history at the University of Copenhagen, so becoming the first female professor in a Danish university. She was immediately recognized as an outstanding researcher with the publication in 1927 of her seminal work on Alderman Cockayne's project and the cloth trade which examined the history of trade and commerce in 17th-century Britain. She later turned to Danish history writing biographies of officials and merchants from the 16th and 17th centuries. From 1942, she edited the Danish Journal of History.[1][2][3]
