This project is based on the observation that Budapest and Vienna around 1900 provided Jews and non-Jews with numerous opportunities for personal encounters, despite historiography about Jews in the emergence of modernity remaining characterized by a narrative of private isolation. The result of this has been a Jewish history conceived on the one hand as particular and not as part of a general history. On the other hand, this narrative of isolation caused the spheres of housing and daily life to be enshrined as isolated enclaves not suitable for Jewish-non-Jewish relations. The absence of study concerning private everyday life in the historiography about Jews in the Habsburg Empire has resulted in a Jewish history of cultural participation but not of private involvement. Without an adequate elaboration of non-exclusive narratives of the Jews in Vienna, we undervalue the impact of Jewish and non-Jewish relations, particularly in daily routines.
