— Zvi Rex 1909
The quote is associated with Theodor Adorno's analysis of a "secondary antisemitism", often explained as an antisemitism not despite of but because of Auschwitz. In Der ewige Antisemit (The Eternal Antisemite) Broder wrote in chapter 5, titled The offender as probation officer, or The Germans will never forgive the Jews for Auschwitz: And for Auschwitz, a sagacious Israeli once said, for Auschwitz the Germans will never forgive us. In 1988, Gunnar Heinsohn identified Broder's sagacious Israeli as Zvi Rix, a friend of his (Heinsohn's), born in Vienna in 1909 and died in Rechovot/Israel in 1981, who had used to concentrate the drive of antizionism in the sentence: »For Auschwitz the Germans will never forgive us!« In 2005, Heinsohn in his book Söhne und Weltmacht (Sons and World-Power) suggested, that Rix had read his Hobbes, and quoted from Leviathan: "To have done more hurt to a man than he can [...] expiate inclineth the doer to hate the sufferer."
But Rix may as well have read the book Post Mortem. The Jews in Germany--now (1968) by Leo Katcher, where the German Jewish journalist Hilde Walter is quoted as follows: "It seems the Germans will never forgive us Auschwitz. That is their sickness and they desperately want a cure. But they want it to be easy, painless. They refuse to go under the knife by facing up to the past and their part in it."
The script for Axel Corti's film Where To and Back Part 2: Santa Fe (winner of a Nymphe d'Or award at the Monte Carlo Festival in February 1986) has the Austrian Jew Treumann who has found refuge in New York during World War II say about his former countrymen: "They'll never forgive us for what they did to us." This caused protests from writers Hans Sahl as well as Stefan Heym, who claimed certain rights to variants of this line, screenwriter Georg Stefan Troller revealed in 2013. But when Troller met with Heym the next time in Paris, Heym generously waived any objections: Jewish jokes are wanderers like the famous punchlines of the comedians. The original author cannot be ascertained any more.
In 1982 a line, which Walter Mehring had sent his fellow refugee from Nazi Germany Hans Sahl in 1948, had been published in Germany:
