The Institute’s only member arrested was freed after months of internment

Evidence

The one exception was Wittfogel, who returned to Germany from Switzerland and was thrown into a concentration camp in March because of his political activities. His second wife, Olga Lang (originally Olga Joffe), herself later to become an expert on Chinese affairs and an assistant at the Institut, worked to secure his release, as did such friends as R. H. Tawney in England and Karl Haushofer in Germany. Wittfogel’s freedom was finally granted in November, 1933, and he was permitted to emigrate to England. — Martin Jay, The Dialectical Imagination, 157

• SHARE: The detail that Haushofer (later of geopolitics infamy) helped secure Wittfogel’s release is the kind of odd connective fact a specific history-interested person would enjoy.
