Scientific tests prove the "Gas Chambers" never existed


Holocaust Deniers Say:

Scientific tests prove conclusively that there were never any gas chambers in Auschwitz.

Holocaust Deniers Argue
The claim that objective science proves the non-existence of the Holocaust began with the Leuchter Report. In his introduction to that report, David Irving writes: "Unlike the writing of history, chemistry is an exact science. . . . The truly astounding results are as set out in this report: while significant quantities of cyanide compounds were found in the small de-lousing facilities of the camp . . . no significant trace whatsoever was found in the buildings which international opinion--for it is not more than that--has always labeled the camp's infamous gas chambers . . . Forensic chemistry is, I repeat, an exact science." 1
The Leuchter Report
First published in 1989 and submitted as evidence during the trial of German-Canadian Holocaust denier and neo-Nazi, Ernst Zündel, the Leuchter Report is one of the cornerstones of Holocaust denial. For his trial, Zündel commissioned self-proclaimed execution-chamber specialist Fred Leuchter to conduct a forensic examination of the gas chambers in Auschwitz. Leuchter went to Auschwitz, where without any official permission, he chipped away samples of brick and stone, which he then sent to a forensics laboratory for investigation.
His report concluded that, "There were no execution chambers at any of these locations." He continued by saying that, in his opinion, "the alleged gas chambers at the inspected sites could not have then been, or now, be utilized or seriously considered to function as execution gas chambers." 2
Zündel submitted the Leuchter Report as evidence in his trial and wanted Fred Leuchter to be a witness for his defense. However, when Leuchter was questioned by the court about his credentials as an expert witness it was discovered that he wasn't licensed as an engineer, his degree was in the humanities, and he had no expertise in chemistry, toxicology or incineration--all subjects he had weighed in on in the Report. The court, therefore, did not let the report be entered as the work of an expert.
The Major Falsifications Of The Leuchter Report
Survivors Explain
Henryk Tauber arrived in Auschwitz on January 19, 1943. He was assigned to a Sonderkommando which burned the bodies and assisted in the gas chamber operations in Cremas 1, 2, and 4. Tauber recalled the gas chambers in Crema 4 after the war: "The gas chambers were about two meters high and had an electric lighting installation on the walls but they had no ventilation system, which obliged the Sonderkommando who were removing the bodies to wear gasmasks." 20 The SS guards regularly wore gas masks when pouring the Zyklon-B pellets into the gas chambers.
Filip Müller, a Slovak Jew who arrived in Auschwitz in April 1942, was put to work as an oven stoker in Crema 1. Müller's job was to drag the corpses from the morgue-turned-gas chamber to the ovens and sort and remove valuables from the abandoned clothing. Later, he was transferred to Birkenau to work in the crematoria and burning pits there.
Müller gave a detailed description of the process of murder in both the Main Camp and Birkenau. He recalled one such gassing in Crema 1: "When the last one had crossed the threshold, two SS leaders slammed shut the heavy iron-studded door which was fitted with a rubber seal, and bolted it . . . the Unterführers on duty had gone onto the crematorium roof . . . They removed the covers from the six camouflaged openings. There, protected by gas-masks, they poured the green-blue crystals of the deadly gas into the gas chamber." 21
The Leuchter Report is junk science. Furthermore, the small traces of HCN found in Leuchter's samples from Cremas 1 through 5 actually demonstrate the opposite of what Leuchter supposedly "proved"--that is, the traces of HCN proves that the gas chambers at Auschwitz-Birkenau did exist.
