Horkheimer had withdrawn from active collaboration by the mid-1950s

Evidence

Horkheimer was forever making new efforts to involve his friend Friedrich Pollock in their theoretical work (successfully, in the case of the credit given to Pollock as a collaborator on the group study and with the publication of his book on Automation: Materials to Evaluate its Economic and Social Consequences as volume 5 of the Frankfurt Contributions to Sociology'). So, too, Adorno was constantly making efforts to involve Horkheimer in their work. Adorno's essay on The Relation between Sociology and Psychology’, which opened Sociologica, was dedicated to Horkheimer and had originally been intended as a joint contribution by Adorno and Horkheimer to the first issue of the journal. Horkheimer’s collaboration did not, however, extend beyond a few notes and suggested changes. In addition, Adorno had produced a censored version', as he put it, of Vernunft und Selbsterhaltung’, the German version of `The End of Reason’, which even in the late 1940s Horkheimer had not wanted to see published in Germany without alterations. — Rolf Wiggershaus, The Frankfurt School, 2007
