He also produced fairy-tale illustrations for the publisher Bruno Cassirer. He had numerous exhibitions, including one in 1914 at the Münchener Neue Secession with Klee, Kokoschka and Jawlensky. He settled in Geneva in 1924. He befriended the local art scene where he came into contact with Maurice Barraud and Eugène Martin. He died in Geneva in 1962. The Kunstmuseum Bern held a large exhibition of his works in 1975.
