Karen Callisen

Karen Herdis Callisen (5 April 1882 – 17 January 1970) was the first woman in Denmark to become a geologist graduate after studying mineralogy and crystallography in 1915. She was employed for the remainder of her career by the University of Copenhagen's Mineralogical Museum, holding the post of curator (museum inspektor) from 1932 until she retired in 1952. She made significant contributions to the geology of Bornholm, specializing in the island's granite. She also devoted particular attention to the composition of meteorites. In addition to her interest in geology, Callisen taught gymnastics from 1921 to 1947 at Ingrid Jespersen's High School in central Copenhagen. She published her geological findings in numerous books and articles. Provided by Wikipedia
