The furniture, interior design and buildings by Friedl Dicker and Franz Singer were exceptional in Vienna in the 1920s and 1930s. Both followed Johannes Itten to the newly founded Bauhaus in Weimar, where they studied from 1919 to 1923. The artistically fruitful activities of their Viennese studio community, founded in 1925, ended with the burgeoning National Socialism. Dicker and Singer and the majority of their clients - mostly Jewish - emigrated abroad. Her works created at the Bauhaus and those from their joint studio work have so far been largely unexplored. In this study, based on extensive source research, the work of the studio community is analyzed for the first time in the context of the Bauhaus and the Viennese architectural landscape. The volume, with numerous previously unpublished images, closes a research gap in the history of Vienna's architecture and the Bauhaus.
