During and following the First World War, Berlin absorbed tens of thousands of Jews seeking new homes. The city’s housing shortage meant that most newcomers were unable to secure personalized dwelling space, and were therefore left to reside in transitional dwellings such as Pensions. The category of dwelling space, however, is largely absent from the prevailing historiography of German Zionism during this period. This paper investigates the often-neglected axes of Jewish domesticity, migration, and Zionism by offering a micro-history of Berlin’s renowned Pension Struck, a space that primarily housed German and East European Jewish migrants with a shared interest in Zionism. Using ego documents—including the unpublished correspondence of former residents Elias Auerbach, Esther Smoira, and Yitzhak Lamdan—the paper shows how the Pension Struck functioned as a key site of Zionist sociability, belonging, and identity for Jews in Berlin from the 1910s through the 1930s. My analysis demonstrates how the concrete domestic space of the Pension afforded its residents a significant degree of attachment to their surroundings in Berlin, while simultaneously functioning as a site of imaginative speculation about the abstract space of Palestine. The paper elucidates the significance of domestic space for the Zionist encounter with Berlin from the 1910s through the 1930s, while also probing the character of cultural exchange between Haifa and Berlin during this formative period. The paper ultimately argues that the residents’ communal longing for Palestine, a process enabled by the physical space of the Pension Struck, constituted an important form of ‘belonging’ in the history of German Zionism.
