Raoul Hausmann (1886-1971) was a German artist and writer who played a significant role in the development of Dadaism. Born in Vienna, he moved to Berlin in 1900 and became involved in the avant-garde art scene. He was a founding member of the Berlin Dada group and contributed to the movement's publications, including the magazine "Der Dada" and the manifesto "First German Dada Manifesto." Hausmann's work included collages, photomontages, and assemblages, which often incorporated found objects and everyday materials. He was also a prolific writer, publishing poetry, essays, and plays. In 1933, he fled Germany for Ibiza, where he continued to create art and write until his death in 1971. Hausmann's work has been exhibited in major museums and galleries around the world and continues to influence contemporary artists today.
