Periodicals played a central role in disseminating Expressionism. These serials, over the course of a few issues—or sometimes decades—built audiences for the new art and defined the scope of the movement. They were aimed not just at professionals (artists, critics, dealers, and publishers) and collectors, but also to the broader, educated middle classes in German society. By including original woodcuts, lithographs, and etchings in addition to reproductions, these periodicals also expanded the potential market of collectors. Some publications, like Herwarth Walden’s Der Sturm or Marées-Gesellschaft’s Ganymed, presented a mix of art and literature, while others were more narrowly focused, like Franz Pfemfert’s Die Aktion, which emphasized politics over art. The Museum has either complete runs or significant holdings of the eight periodicals featured here, which represent a range of positions on the movement.
