Scholarly interest in the flight into exile of intellectuals after 1933 has only recently transformed into a more systematic engagement. While most of the early contributions focused either on single biographical elaborations or on academic schools of thought (Jay 1976; Young-Bruehl 1982; Coser 1984), contemporary scholarship aims to provide a more comprehensive picture by examining the influence of German émigré scholars on entire disciplines and cultures. This change in perspective differs from "exile studies' — negative concepts like displacement or the fate of the exile no longer guide our research (Möller 1984; Jay 1985; Heilbut 1997); instead, positive concepts such as knowledge transfer and acculturation are increasingly being employed (Krohn 1993; Strauss 1999). In this chapter, I aim to apply these concepts — knowledge transfer and acculturation — to a small cluster of émigré scholars who impacted on the intellectual and institutional development of political science and International Relations in the United States.
