She also had connections with the Belgian avant-garde magazine "Het Overzicht", which was directed by Michel Seuphor and Jozef Peeters.

She lived with Rilke from 1914 until 1916 in Vienna, and moved in an artist circle that included, among others, Romain Rolland, Stefan Zweig, Paul Klee, and Oskar Kokoschka.

After 12 years in Switzerland, she moved to Berlin and joined an avant-garde artist group known as the Novembergruppe.
