Our friend and colleague Moishe Postone ז״ל died on 19 March 2018. At the time of his death he was the Thomas E. Donnelley Professor of History and a member of the Committee on Jewish Studies at the University of Chicago. His research and teaching focused on nineteenth and twentieth-century European intellectual history, with emphasis on critical social theories. He was particularly interested in self-reflexive theories of historical context – theories that seek to grasp social, economic, and cultural processes in ways that illuminate the relation of such processes to the theories themselves. His work also focused on the problematic of modern antisemitism and questions of history, memory, and identity in postwar Germany, as well as on the issue of the global transformations of the past three decades and their implications for understanding the historical trajectory of the twentieth century. May his memory be a blessing.
