In 1890 he obtained his PhD from the University of Giessen, later becoming an assistant in mineralogy and geology at the University of Leoben (1892).

From 1895 he was in charge of the mineralogy/geology department at the Museu Paraense in Belém (Brazil), from where he undertook various exploratory projects. In 1898 he began work as a state geologist in Sarajevo, and in 1900 was appointed director of the Bosnian geological Landesanstalt.
