After displaying some artistic talent, he went to study at the Prussian Academy of Arts, the Weimar Saxon-Grand Ducal Art School and the Academy of Fine Arts, Karlsruhe. In 1880, he visited the village of Gutach for the first time as part of an assignment to illustrate the novella "Lorle, die Frau Professorin" by Berthold Auerbach. In 1898, he was named a Professor by Frederick I, Grand Duke of Baden.
He often collaborated with the writer Heinrich Hansjakob, who lived nearby in Haslach.
They shared an interest in preserving the culture of the Black Forest region. The primary and secondary schools in Gutach are named after him, as well as the art museum and the game preserve between Hausach and Schonach.
