Secondary antisemitism is often explained as being caused by the Holocaust (as opposed to or in spite of it).[1] One frequently quoted formulation of the concept, first published in Henryk M. Broder's 1986 book Der Ewige Antisemit ("The Eternal Antisemite"), stems from the Israeli psychiatrist Zvi Rex [he],[2] who once remarked: "The Germans will never forgive the Jews for Auschwitz."[3][page needed][4] The term itself was coined by Peter Schönbach [de], a Frankfurt School co-worker of Theodor W. Adorno and Max Horkheimer, based on their Critical Theory.[5]
