“Cosmopolitan Outsiders adds significantly to recent work asserting the relevance of early twentieth-century plans for European unity to the story of post-1945 integration, brings German scholarship on Fried and Coudenhove-Kalergi to an Anglophone audience, and makes intelligent, nuanced, and persuasive arguments that Pan-Europe must be understood with reference to a specifically Austrian Jewish internationalism, and that colonialism lay at its heart. … ought to be required reading for historical and political geographers interested in these fields.” (Benjamin J. Thorpe, Journal of Historical Geography, July, 2017)
