Well, I have looked at the thread linked to at Skeptics Forum ...
Dr. Nick Terry, who once was the lead moderator at RODOH, can be a nice guy and is probably a good History professor, but he is certainly not an engineer ─ and he is totally wrong about the so-call Nazi homicidal gassings.
Fred Leuchter was an expert on U.S. execution protocols and a technologist familiar with the hardware used for capital punishment. He was recognized by the Toronto court as an expert witness in the second Zündel trial (1988) and he was hired to do some forensic testing for that role at the behest of French Professor of Literature Robert Faurisson, who had already done considerable legwork at the camp sites and in the Auschwitz archives.
Forensic testing of the Nazi "Death Camps" was almost unheard of at the time, during the late Communist era in Poland. It was far easier to do so in West Germany and Austria, or Alsace, which is why those Nazi Concentration Camps were no longer prominent in the postwar Holocaust "Death Camp" Narrative, which was such that signally preferred camps behind the Iron Curtain that were barely accessible to investigators.
Even color photographs of the ruins of Auschwitz and Birkenau were hard to come by in those days, and some of the first available in the West were taken by an eccentric Swedish skeptic named Dietlieb Felderer, who as a Jehovah's Witness had made several pilgrimages to the Auschwitz shrine during the late Communist era, where his co-religionists were persecuted during the war for their blatant pacifism.
No technical experts in the modern postwar period had ever critically examined these Nazi homicidal gaschamber claims at the sites themselves. Mr. Leuchter was a brave man for doing this for besieged Canadian publisher Ernst Zündel, who was being prosecuted for de facto Thoughtcrime due to publishing a 1974 booklet called Did Six-Million Really Die? by Richard Harwood
(a British Nationalist named Richard Verrall), which made various arguments against the Exterminationist and Nazi Death Camp narrative.
Mr. Leuchter was protected by the First Amendment of the U.S. Constitution so he was not charged by the government for thinking or saying the wrong things, but just the same, he ultimately lost his livelihood as an "engineer assuring humane executions," or whatever his business model was, because critically examining the Holocaust from a skeptical standpoint ─ or anything other than abject devotion ─ is the gravest heresy of our postmodern Liberal and Globalist age. Today we would call this "Cancel Culture." Even to doubt the smallest essential jot and tittle of the Big-H mythos is Racist and anti-Semitic by definition, and thus the vilest of Thoughtcrimes today. However, an epistemology getting to the Truth is simply not possible IF doubt can not realistically be part of the methodology of revision, and sacred claims are not (and cannot be) investigated honestly and skeptically.
Fred Leuchter was correct in his outline to conclude that the structures left at the so-called Nazi Death Camps were NOT used for the homicidal gassings of millions. or thousands ─ or even hundreds ─ of persons during the war. However, not all of Leuchter's arguments were sound.That Holocaust proponents wish to affirm the orthodox Holocaust narrative, and are typically WRONG, does not necessarily make Mr. Leuchter's arguments not wrong.
Holocaust Revisionist Friedrich Paul Berg was a real engineer (one with a degree in Mining Engineering from Columbia University) who had published technical research papers on the topic since 1984. Mr. Berg was quick to find problems with Leuchter and Faurisson's over-simplified and dogmatic arguments.
Fritz Berg enthusiastically offered to assist the defense of Ernst Zündel but the capable defense attorney, Mr. Douglas Christie did not believe that complicated or nuanced technical arguments of the type used by Mr. Berg would successfully defend his client ─ and there is great truth to that opinion because of the way that court trials work.
In court, the most persuasive arguments are slam-dunk, cookie cutter paradigms, so Leuchter was used as an expert witness for his wheelhouse, and also the noteworthy British historical author David Irving, and engineer Fritz Berg was not used. However, declarations by courts of law are simply not proper historical methodology.
Professor Faurisson, who like Mr. Leuchter was also not an engineer, issued a famous challenge: "Show me or draw [for] me a homicidal gas-chamber."
Mr. Berg was a degreed engineer and an expert on diesel engines using in mining, Zyklon-B fumigants, and carbon monoxide gas generation, so he did just that. Prof. Faurisson never acknowledged this honestly and he and Mr. Leuchter merely doubled-down on their claims that Leuchter was an Engineer and that his "Execution Theater" arguments based on U.S. capital punishment hardware and protocols were unimpeachable and vital.
In doing so, Engineer Berg demolished many of the Holocaust gassing claims by actually studying the mass-gassing extermination problem itself from an engineer's perspective, i.e., exactly what the Germans would have needed to do had they really been serious in killing people as was claimed.
What Berg found was that this would have actually been quite easy for real engineers to do had this been a real technical problem for the Germans or Nazis to solve. Mr. Berg's findings are actually stronger arguments from the Revisionist viewpoint than the notion that the Germans could not have done something artificially weird. More about that later. I intend to put Mr. Berg's Revisionist essays and original research back Online for Reference purposes at this forum as time permits.
For now, I will recommend the Leuchter Report
as part of the Revisionist canon, but only the "Critical Edition" which was edited by degreed Chemist Germar Rudolf. I also do not begrudge Mr. Leuchter for his bravery and pathbreaking work for the Truth.
One should probably start with the introductory book on Holocaust Revisionism by Thomas Dalton, Ph.D. called Debating the Holocaust: a new look at both sides (c. 2009)
. Of course, this harmless and thought-provoking book is banned by Amazon, but you can get it from the Castle Hills Publishers bookstore at the CODOH.com website: LINK
