In 1913 she married Dr. Steinitz and started a literary salon in Hannover. She dedicated herself to painting and drawing and got involved in the Dada movement. She founded the publishing house APOSS Verlag, whose mission was to produce ‘typographically new and progressive work’. From 1924 she wrote children’s book in collaboration with Kurt Schwitters: Der Hahnepeter, Das Märchen vom Paradies, and Die Scheuche. As a freelance, she wrote short stories for Hannoversche Kurier and Hannoverscher Anzeiger. She worked also as a photojournalist. From 1935 the Nazi regime forced her to quit writing and in 1937 she moved to New York to become a commercial artist and researcher. In 1942 following her husband’s death, she moved to Los Angeles, where she worked as a librarian and became an accomplished scholar of Leonardo da Vinci.
