Welcome to CODOH!

Watch presentations of our 2026 Holocaust Summit (Feb. 7, 2026)

The aim of the Committee for Open Debate on the Holocaust is to promote intellectual freedom permitting an uncensored and unimpeded, yet always civil discourse on the “Holocaust” narrative, and to offer a forum to those who contest the orthodox Holocaust narrative. As an introduction, we recommend:

Holocaust Encyclopedia

El Gran Tabu: Get to know CODOH’s founder Bradley Smith, and Germar Rudolf, who continues Brad’s legacy at CODOH, as well as Ernst Zündel, a major revisionist activist.

Always Hot: The new standard reference work summarizing in 591 nutshell entries the research results of skeptical Holocaust research. This 646-page letter-size “Nuke Book” gives you an uncensored and unconstrained look at all the pertinent evidence that upholds the orthodox Holocaust narrative: the true, the false, and the mendacious. It also exposes the various forces and influences that have dictated how this narrative was formed, and how it is protected from skeptical prying eyes. Learn about the biggest propaganda campaign mankind has ever seen, and how it braced the postwar world psychologically. This encyclopedia gives you all the information they ever wanted, and information you didn’t even know exists, right at your fingertips. Learn more…

    Siegfried Verbeke was there when he was needed, and when it mattered. Every time. First, some background: In 1994, the German authorities were hell-bent at choking all efforts to publish new, trail-blazing revisionist research. The 1993 German original of my expert report on the chemistry of Auschwitz (Holocaust Handbooks, Vol. 2) induced the German thought…

  • Germar Rudolf was born on October 29, 1964, in Limburg, Germany. He studied chemistry at Bonn University, where he graduated in 1989 as a Diplom-Chemist, which is comparable to a U.S. PhD degree. From 1990-1993, he prepared a German PhD thesis at the Max Planck Institute for Solid State Research in conjunction with the University of Stuttgart, Germany. Parallel to this and in his spare time, Rudolf prepared an expert report on chemical and technical questions of the alleged gas chambers of Auschwitz (see The Chemistry of Auschwitz). He conclude in it that "the alleged facilities for mass extermination at Auschwitz and Birkenau were not suited for the purpose as claimed." As a result, he had to endure severe measures of persecution in subsequent years. Hence, he went into British exile, where he started a revisionist publishing outlet. When Germany asked Britain to extradite Rudolf in 1999, he fled to the U.S. There he applied for political asylum, expanded his publishing activities, and in 2004 married a U.S. citizen. In 2005, the U.S. granted him an immigrant visa based on his marriage, but seconds later arrested and subsequently deported him back to Germany in crass violation of U.S. law. In Germany, where he was put in prison for 44 months for his scholarly writings, some of which he had published in the U.S., where they are perfectly legal. Since not a criminal under U.S. law, he managed to immigrate permanently to the U.S. in 2011. Rudolf has published more than 90 books (currently available through Armreg US and Armreg UK), among them the 54 volumes of the Holocaust Handbooks. He has compiled 9 documentaries and authored 20 non-fiction books, among them the bestselling Holocaust Encyclopedia. With a brief interruption, he has managed the free-speech organization Committee for Open Debate on the Holocaust since 2014, where we defend free speech at the forefront of corporate censorship and governmental persecution. In 2017, he became chief editor of CODOH’s quarterly periodical Inconvenient History. In early 2025, he launched the Holocaust Academy, dedicated to bringing critical thinking to Holocaust education. In that context, he organized the 2026 Holocaust Summit, dedicated to “Tackling the Most-Harmful Ideology Undermining Peace, Truth and Freedom Worldwide”.
