The article discusses the “paradox of the late (around 1940) arrival of academic applied mathematics in the U.S.” as compared to Europe, in particular Germany. A short description of both the indigenous traditions in the U.S. and (in some more detail) of the transfer of scientific ideas, persons, and ideals originating in Europe, particularly in Germany, is given, and some theses, relevant literature, and a tentative solution of the “paradox” are provided.
