This co-edited volume offers new insights into the complex relations between Brussels and Vienna in the turn-of-the-century period (1880-1930). Through archival research and critical methods of cultural transfer as a network, it contributes to the study of Modernism in all its complexity. Seventeen chapters analyse the interconnections between new developments in literature (Verhaeren, Musil, Zweig), drama (Maeterlinck, Schnitzler, Hofmannsthal), visual arts (Minne, Khnopff, Masereel, Child Art), architecture (Hoffmann, Van de Velde), music (Schonberg, Ysaye, Kreisler, Kolisch), as well as psychoanalysis (Varendonck, Anna Freud) and cafe culture. Austrian and Belgian artists played a crucial role within the complex, rich, and conflictual international networks of people, practices, institutions, and metropoles in an era of political, social and technological change and intense internationalization.
