Robert Scheibe, a German geologist, obtained his doctoral degree at the University of Halle, Germany, in 1882 with a thesis entitled Krystallographische untersuchung des Lupinins und seiner Salze. He may have visited German South West Africa (now Namibia) in or just before 1888, for in that year he published two brief notes (in German) on the gold-bearing rocks of Otjimbingwe and on the mineral tourmaline in copper ore from the Luderitz area, in the Zeitschrift der Deutschen Geologischen Gesellschaft. Subsequently he wrote many papers on mineralogy and crystallography. Years later he was a professor in Berlin, but worked in Namibia for some time, for in 1910 he presented the South African Museum, Cape Town, with a series of rock samples from the volcanic pipes of Geitsi Gubib (Brukkaros). Between 1903 and 1910 he wrote a number of papers on the diamond deposits of Namibia. These included a paper on "blue ground" (the matrix of diamond-bearing volcanic pipes) in German South West Africa (Deutsche Kolonial Zeitung, 1903); a comparison between the blue ground of Namibia and that of South Africa (Programm der Königlichen Bergakademie, Berlin, 1906-1907); three papers on the nature of the diamond fields in Namibia, the occurrence of diamonds and blue ground in the territory from a geological perspective, and the Luderitz diamond area (Verhandlungen des Deutschen Kolonialkongresses, Berlin, 1910); and a contribution on the nature and significance of diamond occurrences in Namibia (Naturwissenschaftliche Wochenschrift, 1911).
Scheibe appears to have spent the next phase of his career as professor of mining in Bogota, Colombia. He published (in Spanish) on the geology of that country in 1922 and after his death a compilation of official geological studies in Colombia between 1917 and 1933 was published (in Spanish) under his name (Bogota, 1933).
