[Germar Rudolf](https://germarrudolf.com/?ref=jermwarfare.com), born in 1964 in Germany, is a chemist who graduated from Bonn University. 

Initially accepting the official narrative about Zyklon B, his scientific training eventually led him to question the claims surrounding what occurred in the Auschwitz gas chambers.

Germar's [work](https://germarrudolf.com/germars-views-2/202-some-technical-and-chemical-considerations-about-the-gas-chambers-of-auschwitz-and-birkenau/?ref=jermwarfare.com), which is loosely based on the [*Leuchter Report*](https://cdn.jermwarfare.com/Library/Videos/Holocaust/THE%20LEUCHTER%20REPORT.mp4?ref=jermwarfare.com), raises serious doubts about the physical evidence behind the Zyklon B account. In other words, his conclusion is that there is no evidence to suggest anyone was exterminated in gas chambers in Auschwitz or any other camp, using the claimed gas.

He adds that Jews (and others) undoubtedly suffered, pointing out that the camps experienced truly dreadful conditions at times.

> That Jews suffered greatly during the Third Reich is not in question, but the notion of a premeditated, planned and industrial extermination of Europe’s Jews with its iconic gas chambers and immutable six million are all used to make the Holocaust not only special but also sacred.
