In this comprehensive collection, director of the Gerhard Richter Archive Dietmar Elger gathers the many artists and elements of this urgent, scattered, complex movement into one authoritative overview of its protagonists, principles, and essential role in 20th-century modernism. Finding a critical calm amid the frenzy of color and distortion, the book distills Expressionism's leading collectives, Die Brücke and Der Blaue Reiter, as well as its regional characteristics across its Berlin and Munich hubs, and its North German, Rheinland, and Viennese variants.
