The Viennese artists’ association Hagenbund played a crucial role in the artistic scene of not only Vienna but of Central Europe in general. Active from 1900 to 1938, the group united several different art movements under its umbrella and helped to introduce a new creative dynamic at a time when the Vienna Secession was slowly losing its impact. In that context, the liberal political and artistic attitude of the Hagenbund membership was revolutionary. The Hagenbund counted more than 250 members, among them Georg Merkel, Oskar Laske, Carry Hauser, Otto Rudolf Schatz, Emil Strecker, and Fritz Schwarz-Waldegg. This volume traces the history of the Hagenbund and its influence, offering the first sustained analysis of the group in an art-historical context. Packed with more than three hundred color images, it will be the standard work on the Hagenbund for decades to come.
