The Holocaust drew little scholarly interest until recently

Evidence

What would, by the late 1950s, be known as the Holocaust, did not initially stimulate much interest in the history and nature of antisemitism outside small sections of the Jewish intellectual world. Indeed, the current obsession with the Holocaust in popular culture as well as Western academia is of very recent origin. — David Theo Goldberg, John Solomos, A Companion to Racial and Ethnic Studies, 487
