Global InformationLeuchter report information
The Leuchter report is a pseudoscientific[1] document authored by American execution technician Fred A. Leuchter, who was commissioned by Ernst Zündel to defend him at his trial in Canada for distributing Holocaust denial material. Leuchter compiled the report in 1988 with the intention of investigating the feasibility of mass homicidal gassings at Nazi extermination camps, specifically at Auschwitz. He traveled to the camp, collected multiple pieces of brick from the remains of the crematoria and gas chambers (without the camp's permission), brought them back to the United States, and submitted them for chemical analysis. At the trial, Leuchter was called upon to defend the report in the capacity of an expert witness; however, during the trial, the court ruled that he had neither the qualifications nor experience to act as such.
Leuchter cited the absence of Prussian blue in the homicidal gas chambers to support his view that they could not have been used to gas people. However, residual iron-based cyanide compounds are not a categorical consequence of cyanide exposure. By not discriminating against that, Leuchter introduced an unreliable factor into his experiment, and his findings were seriously flawed as a result. In contrast, tests conducted by Polish forensic scientists (who discriminated against iron-based compounds) confirmed the presence of cyanide in the locations, in accordance with where and how it was used in the Holocaust. In addition, the report was criticized as Leuchter had overlooked critical evidence, such as documents in the SS architectural office which recorded the mechanical operation of the gas chambers and others which verified the rate at which the Nazis could burn the bodies of those gassed.[2]

- "Another common tactic of the deniers is to engage in historical inquiries that on the surface appear legitimate but upon close examination prove to be based on pseudo-science. One prominent example was the investigation of the Auschwitz gas chambers by Fred Leuchter [...]. Detailed study of the "Leuchter Report" revealed that it was based on erroneous assumptions (cyanide does not penetrate deeply into concrete). It also emerged that Leuchter had falsified his credentials and overstated his expertise. Despite this, his report is still cited by deniers." Cull, Nicholas John. Culbert, David Holbrook.

- "After the trial, both Irving and Zündel published the results of Leuchter's trial research as The Leuchter Report: The End of a Myth, despite the fact that the court rejected both the report and Leuchter's testimony.

- "Leuchter's report contained a considerable amount of scientific, or, as it turned out, pseudo-scientific analysis of chemical residues on the gas chamber walls, and similar matters. It was quickly discredited, not least on the basis of Leuchter's failure adequately to defend his findings on the witness stand." Evans, Richard J.

Inventing and promoting pseudoscience [the art of using "expert witnesses"]: Leuchter claims that the gas chamber was not really used against human beings. He concludes this after a brief vacation to Auschwitz and several trips to a local library. He states that the design of the "gas chamber" was compatible only with a disinfecting facility. Error #1: Leuchter estimates that a certain crematorium at Auschwitz could process only 156 bodies. He was apparently unaware of an SS report which confirms that the same building (which he describes) destroyed 4756 bodies in the course of a single 24 hour period.
