Arthur Butz is best known as a Holocaust denier and contributor to organizations and websites that defend the Nazis. His infamous book “The Hoax of the Twentieth Century” claims, among other things, that the “alleged slaughter of millions of Jews by the Germans, during World War II, did not happen.” At the 13th IHR conference in 2000, Butz defended Nazi leaders and dismissed eyewitness testimony of Holocaust survivors, claiming, “The Auschwitz legend rests entirely on the alleged eye witness accounts. The extermination — so-called — can’t be deduced or even suspected from the documents or the ordinary historical record of how the principals behaved or from the evidence at the site.” In a 1991 article published in the Daily Northwestern, Butz claimed that the war crimes trials that took place following WWII were only held to establish the “legend” of the Holocaust.
In 2005, Butz expressed his support for former Iranian President Mahmoud Ahmadinejad for calling the Holocaust a “myth,” saying, “I congratulate him on becoming the first head of state to speak out clearly on these issues and regret only that it was not a Western head of state.” In response to these comments, University President Henry S. Bienen issued a statement arguing that his comments were, “a contemptible insult to all decent and feeling people.” While distancing himself and the University from Butz’s statements, Bienen still maintained that as a tenured Professor, Butz is entitled to express his personal views so long as they are not expressed in his classroom.
In 2006, sixty of Butz’s colleagues signed a petition calling his Holocaust denial “an affront to our humanity and our standards as scholars,” and called on Butz to “leave our Department and our University and stop trading on our reputation for academic excellence.”
