The correct answer is Raoul Hausmann. He was an Austrian
artist and writer. And he was a forefather and dominant figure of the Dada movement
in Berlin, who was
known particularly for his ironic photomontages and
his provocative writing on art. One of the important
figures there also includes the experimental photographic collages, sound
poetry and institutional reviews that has a profound influence on the European
Avant-Garde in the aftereffects of World War I.
