David Nirenberg, an American historian, is Deborah R. and Edgar D. Jannotta Professor of Medieval History and Committee on Social Thought at the University of Chicago, as well as the Dean of the Social Sciences Division at the University and the founding Roman Family Director of the Neubauer Family Collegium for Culture and Society. He has a particular interest in Christian, Jewish, and Muslim thought in Medieval Europe, and works in the Department of Romance Languages and Literatures, the Center for Middle Eastern Studies, the Center for Jewish Studies, and the College of the University of Chicago.
Nirenberg's 2013 book Anti-Judaism: The Western Tradition is not a history of anti-Semitism, rather, it focuses "on the role of anti-Judaism as a constitutive idea and an explanatory force in Christian and post-Christian thought—though it starts with Egyptian arguments against the Jews and includes a discussion of early Islam, whose writers echo, and apparently learned from, Christian polemics." Pulling on an array of sources from across the centuries, Nirenberg demonstrates the potency of "imaginary Jews" in "works of the imagination, profound treatises, and acts of political radicalism." Described as "an extraordinary scholarly achievement",Anti-Judaism: The Western Tradition argues "that a certain view of Judaism lies deep in the structure of Western civilization and has helped its intellectuals and polemicists explain Christian heresies, political tyrannies, medieval plagues, capitalist crises, and revolutionary movements." Christopher Smith of King's College London argues that Anti-Judaism represents, "the culmination of a career volte-face in respects to his methodological approach. His 1996 work Communities of Violence: Persecution of Minorities in the Middle Ages rejected a longue durée history of anti-Semitism." Whereas, "in Anti-Judaism, Nirenberg allows for a continuation of trends in the development of a shared concept of anti-Judaism built on and progressed over" a period of three thousand years.
