Abstract
The paper provides a study in the early history of social research on migration and integration with a focus on Switzerland in the 1960 and 1970s. It takes a closer look at two landmark studies of German-speaking migration scholars in order to reconstruct the emergence of a new ‘sociologic’ of immigration and integration that shaped not only the knowledge production but also the practices of civil and governmental actors and institutions in Switzerland in the 1960s and 1970s. The intellectual pathways of Rudolf Braun and Hans-Joachim Hoffmann-Nowotny show that Swiss social research on immigration forms part of an international landscape of migration studies emerging within the postwar world order. The case study develops a new angle on the historical genealogy of ‘postmigrant societies’ like Switzerland.
