Psychoanalysis and Marcuse’s arrival marked the end of the Grünberg era at the Institut.

Evidence

With the introduction of psychoanalysis to the Institut, the Granberg era was clearly over. … Pollock, Horkheimer, Wittfogel, and Grossmann all contributed articles, but most of the pieces were by older friends from Griinberg’s Viennese days, such as Max Beer and Max Adler. The change this symbolized was given further impetus by the acceptance of a new member in late 1932, Herbert Marcuse, who was to become one of the principal architects of Critical Theory. — Martin Jay, The Dialectical Imagination, 153
