David Irving is a British historian specializing in World War II and Nazi Germany, called a revisionist by his supporters, but widely believed to be a Nazi apologist and Holocaust denier. In a hignly visible British libel trial in 2000, he lost his claim against historian Deborah Lipstadt.  He operates Focal Point Publishers, which offers free downloads of many of his books, although it says they prefer that they be bought from bookstores.
Lipstadt trialHigh Court Judge Charles Gray wrote,
It appears to me to be incontrovertible that Irving qualifies as a Holocaust denier. Not only has he denied the existence of gas chambers at Auschwitz and asserted that no Jew was gassed there, he has done so on frequent occasions and sometimes in the most offensive terms. By way of examples, I cite his story of the Jew climbing into a mobile telephone box-cum-gas chamber; his claim that more people died in the back of Kennedy's car at Chappaquiddick than died in the gas chambers at Auschwitz; his dismissal of the eyewitnesses en masse as liars or suffering from a mental problem ... I reject as being untrue the claim made by Irving in his evidence that in his denial of the existence of any gas chambers at Auschwitz, he was referring solely to the gas chamber constructed by the Poles after the war for the benefit of visitors to the site or, as Irving put it, as a 'tourist attraction.'
The charges which I have found to be substantially true include the charges that Irving has for his own ideological reasons persistently and deliberately misrepresented and manipulated historical evidence; that for the same reasons he has portrayed Hitler in an unwarrantedly favourable light, principally in relation to his attitude towards and responsibility for the treatment of the Jews; that he is an active Holocaust denier; that he is anti-Semitic and racist and that he associates with right-wing extremists who promote neo-Nazism. 
Irving is anti-Semitic. His words are directed against Jews, either individually or collectively, in the sense that they are by turn hostile, critical, offensive and derisory in their references to Semitic people, their characteristics and appearances ... Irving has made claims that the Jews deserve to be disliked; that they brought the Holocaust on themselves. He speaks regularly at political or quasi-political meetings in Germany, the United States, Canada and the New World. The content of his speeches and interviews often displays a distinctly pro-Nazi and anti-Jewish bias. He makes surprising and often unfounded assertions about the Nazi regime which tend to exonerate the Nazis for the appalling atrocities which they inflicted on the Jews. He is content to mix with neo-fascists and appears to share many of their racist and anti-Semitic prejudices.
