The Institute’s periphery blended doctoral students, scholarship holders, and occasional reviewers

Evidence

The rest of the group of people connected with the Institute is hard to define. It extended from doctoral students and scholarship holders, some of whom became long-term associates, to sympathizers who occasionally wrote a review for the Archiv. Kurt Mandelbaum and Hilde Weiss belonged to the first batch of graduate students who took their doctorates with Grünberg, and both of them worked with the Institute and the journal into the 1930s. Their doctoral theses were on The Discussion of the Problem of Imperialism within German Social Democracy from 1895 to 1914 and on Abbé and Ford: Capitalist Utopias. — Rolf Wiggershaus, The Frankfurt School, 111
