Deborah Lipstadt's 1993 book, "Denying the Holocaust", sharply criticized various Holocaust deniers, including British author David Irving, for deliberately misrepresenting evidence to justify their preconceived conclusions. In the book, Lipstadt named Irving as "one of the more dangerous" Holocaust deniers, because he was a published author, and was viewed by some as a legitimate military historian. He was "familiar with historical evidence", she wrote, and "bends it until it conforms with his ideological leanings and political agenda". In 1996, Irving filed a libel suit against Lipstadt and her publisher, Penguin Books. Irving, who appeared as a defense witness in Ernst Zündel's trial in Canada, and once declared at a rally of Holocaust deniers that "more women died in the back seat of Edward Kennedy's car than ever died in a gas chamber at Auschwitz," claimed that Lipstadt's allegation damaged his reputation. American historian Christopher Browning, an expert witness for the defense, wrote a comprehensive essay for the court summarizing the voluminous evidence for the reality of the Holocaust, and under cross-examination, effectively countered all of Irving's principal arguments to the contrary.Cambridge historian Richard J. Evans, another defense expert witness, spent two years examining Irving's writings and confirmed his misrepresentations, including evidence that he had knowingly used forged documents as source material. After a two-month trial in London the trial judge, Justice Charles Gray, issued a 333-page ruling against Irving, which referred to him as a "Holocaust denier" and "right-wing pro-Nazi polemicist."[97
