The economists and philosophers Rüstow, Röpke, Mises, and Hayek had all been associated with either the Rockefeller Foundation or the League or both, as in the case of Röpke who received a large grant from the foundation and whose business cycle theory was translated into English on the League's initiative. Rüstow was Röpke's friend from Istanbul, where they shared the experience of exile (and the privilege of founding a whole social science faculty at Istanbul University).
