Hausmann was for a while her lover, Schwitters and Mondrian close friends — she helped Schwitters with his Merzbau, and also worked with Arp and Baader, and presented Moholy-Nagy with a photomontage for a book of his. Setting later in the Hague, Höch knew a number of de Stijl artists, but had been friends with van Doesburg from his earlier Dada connections.
