Faurisson's view is supported by the lack of physical evidence for gas chambers.
*1 - Robert Faurisson recounts how the blueprints of the Birkenau crematoriums came to public attention:
A look back at my discovery, on March 19, 1976, of the building plans for the Auschwitz and Birkenau crematoria
On March 19, 1976, I discovered the building plans for the Auschwitz
crematoria in the Auschwitz State Museum archives. Plans that had been
kept carefully hidden since 1945. And for good reason: they refuted
the case for “the Holocaust”!
Two of these drawings confirmed that the Auschwitz camp itself had, at
the start (until August 1943), possessed a Krematorium, a building
with two main rooms: first, a mortuary called a Leichenhalle or
“corpse hall”, then, a room housing cremation ovens as well as a
reserve of coke and funerary urns. Afterwards (from January 1944), the
interior of the room containing the ovens, coke and urns was
dismantled, the whole building being transformed into a
Luftschutzbunker für SS Revier mit einem Operationsraum, or concrete
air-raid shelter for an SS infirmary with operating room.
Still other drawings showed that in 1943 a total of four crematoria
had been built at Auschwitz-Birkenau; the first two, Krematorium II
and Krematorium III, were equipped with Leichenkeller or “corpse
cellars” and, at ground level, a room with cremation ovens; the other
two crematoria, Krematorium IV and Krematorium V, also contained
spaces for the keeping of corpses, either for cremation or other
purposes. For photographs of those crematoria and those plans, one may
refer to the extracts below from Serge Thion’s book Vérité historique
ou vérité politique ? Le dossier de l’affaire Faurisson. La question
des chambres à gaz (p. 317, 320), Paris, Editions la Vieille Taupe,
1980 (available for purchase from Editions Akribeia, 45/3, Route de
Vourles, 69230 St Genis-Laval, France; €28).
All of these building plans made nonsense of the claims that the
structures in question had housed vast chemical slaughterhouses for
Following Faurisson's revelation of the blueprints a French pharmacist, Jean-Claude Pressac, undertook a study of the crematoriums and wrote what I believe is generally accepted as the definitive book on the subject, 'Auschwitz - Technique and Operation of the Gas Chambers', where we read .. Page 429
As for the technical drawings of the Krematorien, cited in legal
actions and described as proving that they were planned for large
scale assassination by gas (which is in fact incorrect). NOT ONE
explicitly mentions in so many words anything like: Blausaüre (prussic
acid) Vergasungs- or Gaskammer or -keller [gassing or gas chamber or
cellar]. This is not because the drawings were “camouflaged” in any
way, but is simply because the buildings concerned were converted from
their original function, cremation pure and simple, and transformed
for criminal use, so that the compromising words could not have been
written on the original drawings of Krematorien II and III, and were
probably left out on those of IV and V.
In the final analysis, there remain only the various items of
correspondence and offical documents of German origin. Through the
“slips” that can be found in them, they form a convincing body of
presumptive evidence and clearly indicate the presence in the four
Birkenau Krematorien (II, III, IV and V) of gas chambers using a
prussic acid disinfestation agent sold under the name of “Zyklon-B”.
In 1979-80, it was impossible to go any further than this, i.e. to
demonstrate with the aid of “concrete” documents that these gas
chambers had been used to execute human beings. At the end of the
“Faurisson trial”, nobody had yet managed to produce “one proof ...
one single proof” of the existence of “homicidal gas chambers” in
Summary: Pressac found no physical evidence that the crematoriums housed gas chambers, or any 'direct' documentary evidence, instead he found what he characterized as 'traces' or 'slips' in some German documents which gave the secret away.
The Birkenau 'gas chambers' were built as morgue rooms in crematoriums. When the Soviets liberated Majdanek there was extensive propaganda about the Majdanek gas chambers, and presumably as a result the Nazis dynamited the Auschwitz crematoriums before they evacuated the camp. However, they only blew up the furnace rooms, the morgue rooms were not dynamited but their roofs collapsed almost totally. Here is a photo of Germar Rudolf inspecting a Birkenau crematorium morgue room where the roof had not completely collapsed-
There have been several analyses of the chemistry of the walls in the alleged gas chambers starting with that of Fred Leuchter, they are all summarized in this video by Rudolf (shown taking samples above)
that demonstrates that there is no chemical evidence that the morgue rooms were gas chambers.
Beyond that there is this admission by foremost Holocaust scholar Robert van Jan Pelt, that there is no physical evidence for 99% of the holocuast:
Ninety-nine per cent of what we know we do not actually have the
physical evidence to prove . . . it has become part of our inherited
I don't think that the Holocaust is an exceptional case in that sense.
We in the future – remembering the Holocaust – will operate in the
same way that we remember most things from the past. We will know
about it from literature and eyewitness testimony. . . .
*2 - The krema I ‘gas chamber’ at Auschwitz which is still being shown to millions of visitors every years was ‘reconstructed’ in 1948. This was known by a few scholars but was revealed to the world in 1992 in the video ‘David Cole Interviews Dr. Frantisek Piper’:
As can be seen from the video the ‘gas chamber’ was being presented in its ‘found’ condition in 1992. This in itself is truly remarkable as the door into the ‘gas chamber’ is a standard office door with a large plate glass window!
In the book ‘Auschwitz 1270 to the Present’ by Holocaust scholars Robert Jan van Pelt and Deborah Dwork the reconstruction is described:
When Auschwitz was transformed into a museum after the war, the
decision was taken to concentrate the history of the whole complex
into one of its component parts. The infamous crematoria where the
mass murders had taken place lay in ruins in Birkenau, two miles away.
The committee felt that a crematorium was required at the end of the
memorial journey, and crematorium I was reconstructed to speak for the
history of the incinerators at Birkenau. This program of usurpation
was rather detailed. A chimney, the ultimate symbol of Birkenau, was
re-created; four hatched openings in the roof, as if for pouring
Zyklon B into the gas chamber below, were installed, and two of the
three furnaces were rebuilt using original parts. There are no signs
to explain these restitutions, they were not marked at the time, and
the guides remain silent about it when they take visitors through this
building that is presumed by the tourist to be the place where it
*3 - there is no physical proof that a single prisoner was gassed with HCN -
Physical scientific proof would consist of the body of a prisoner that was autopsied and that showed signs of HCN (hydrogen cyanide) poisoning.
At the end of the war the US sent a team of forensics investigators into the camps headed by Dr. Charles Larson. They conducted more than 100 autopsies at Dachau and twenty other camps. Not a single body showed signs of poisoning of any sort. Larson wrote a book, ‘Crime Doctor’, which is available on Amazon.
I did a lot of toxicological analysis to determine the facts and
removed organs from a cross-section of about 30 or 40 bodies and sent
them into Paris to the Army's First Medical Laboratory for analysis,
since I lacked the proper facilities in the field. The reports came
back negative. I could not find where any of these people had been
In an interview with the Wichita Eagle, 1 April 1980, he called part of the holocaust a hoax.
Larson has talked little publicly about the war experience. One reason
for his silence has been that his autopsy findings conflicted with the
widely held belief that most Jews in Nazi camps were exterminated by
gassing, shooting or poisoning.
"What we’ve heard is that six million Jews were exterminated. Part of
that is a hoax," Larson said
…most died as a result of the conditions to which they were subjected
rather than mass exterminations...
..autopsies showed that "death by gassing and shooting were rare.
Never was a case of poisoning uncovered."
