Having grown up in Germany or France, they have crossed the border between the linguistic and cultural areas several times, both literally and metaphorically. As border crossers/frontaliers, they have also become cultural mediators/passeurs de culture. In their respective elds - art, literature, science - they have provided impulses and opened up new possibilities by building bridges. They have developed cultural syntheses that others have been able to build upon, whether in Germany, France or beyond. This volume brings together individual studies on David d'Angers, Louis Aragon, Ernst Robert Curtius, Émile Durkheim, Hans Hartung and Wols, Victor Hugo, Julius Meier-Graefe, Edgar Quinet, Germaine de Staël and Johann Georg Wille.
