In 1897 he received his habilitation in mineralogy from the University of Halle with a thesis on barite deposits in the Odenwald. The same year he became a professor at the Technical University of Karlsruhe. In 1900, while performing geological research in Brazil, he fell victim to yellow fever, dying in the state of Pará at the age of 32.
