Carl Krause qualified as a mining engineer at the Koenigliche Bergakademie (Royal School of Mines) in Freiberg, Sachsen, Germany, and subsequently obtained the degree Doctor of Engineering (D Eng) at the University of Dresden. He became a member of the Geological Society of South Africa in 1908 and remained a member until at least 1914. His geological work was done in Namibia during these years. First he contributed "Notes on the German South West African diamonds", a brief account of the German view that the diamonds originated on the sea floor, to the Transactions of the Geological Society of South Africa (1910, Vol. 13, pp. 61-64). Subsequently, following Georg Hartmann*, he explored the Kaokoveld in the north of the territory and described his findings in "Ueber die Geologie des Kaokofeldes in Deutsch-Suedwestafrika" in the Zeitschrift fuer praktische Geologie (1913, Vol. 21, pp. 64-70). This brief but informative article was accompanied by an excellent geological and topographical map, compiled by J. Kuntz* on a scale of 1:800 000.
