Raoul Hausmann was one of the most innovative avant-garde artists of the modernist era. Art and life, in his view, were inextricably connected. His desire to discard familiar forms and constantly enact “tomorrow” made him a trailblazer in multi-media art. As a Dadaist he was among those who invented collage, but he also devised synaesthetic apparatus, penned experimental texts, gave performances that explored the relationship between body, sound and space, and merged the visual with the haptic in his photogra-phy. Throughout his life, not only in his art but also in his quest for new ways to live and to think the world, he was eager to break free of convention and swim against the bourgeois tide.
