Until 1933, he was secretary of the German Society for Sociology (DGS). After the ``closure'' of the DGS by Hans Freyer and the Research Institute for Social Sciences by the Nazis in 1934 he went for a year to the United States. His successor was Willy Gierlichs. Upon his return, Wiese taught economics at a closed circle of listeners.
