From Wikipedia, the free encyclopedia. Frederick A. (Fred) Leuchter, Jr. (born 1944) is an American Federal Court qualified expert in execution technology and author of forensic Holocaust denial material. He claims to have improved the design of instruments for capital punishment and had execution equipment contracts with several states. Subsequently, Leuchter became known for his testimony in defense of Holocaust denier Ernst Zündel in 1988 His study for Zündel's trial is referred to as the Leuchter report after it was published by Zündel as such and is often framed as a scientifically based work of Holocaust denial, though his research methods and findings have been refuted. An Errol Morris documentary on the controversy, entitled Mr. Death: The Rise and Fall of Fred A. Leuchter, Jr., was released in 1999. Description above from the Wikipedia article Fred A.
