What happened in 1920s Cologne 'after Dada'? Whilst most standard accounts of Cologne Dada simply stop with Max Ernst's departure from the city for a new life as a surrealist in Paris, this book reveals the untold stories of the Cologne avant-garde that prospered after Dada but whose legacies have been largely forgotten or neglected. It focuses on the little known Magical Realist painter Marta Hegemann (1894-1970). By re-inserting her into the histories of avant-garde modernism, a fuller picture of the gendered networks of artistic and cultural exchange within Weimar Germany can be revealed. This book challenges orthodox interpretations of the Cologne avant-garde by demonstrating the existence of a continued active and vibrant avant-garde artistic culture in the city 'after Dada' in which women artists, critics, dealers and collectors played a major role. After Dada: Marta Hegemann and the Cologne avant-garde is an important addition to research on Weimar visual culture and will be invaluable to students and specialists in the field.
