Ernst Christof Friedrich Zündel (April 24, 1939 – August 5, 2017) was a German publisher and pamphleteer known for promoting Holocaust denial. He had been jailed several times: in Canada for publishing literature "likely to incite hatred against an identifiable group", and on charges of being a threat to national security; in the United States, for overstaying his visa; and in Germany for charges of "inciting racial hatred". He lived in Canada from 1958 to 2000.
In 1977, Zündel founded a small press publishing house called Samisdat Publishers, which issued such neo-Nazi pamphlets as his co-authored The Hitler We Loved and Why and Richard Verrall's Did Six Million Really Die? The Truth At Last, which were both significant documents to the Holocaust denial movement. Verrall's pamphlet should not be confused with Barbara Kulaszka's book Did Six Million Really Die? Report on the Evidence in the Canadian "False News" Trial of Ernst Zündel, 1988.
On February 5, 2003, Ernst Zündel was detained by local police in the U.S. and deported to Canada, where he was detained for two years on a security certificate for being a foreign national considered a threat to national security pending a court decision on the validity of the certificate. Once the certificate was upheld, he was deported to Germany and tried in the state court of Mannheim on outstanding charges of incitement of Holocaust denial dating from the early 1990s. On February 15, 2007, he was convicted and sentenced to the maximum term of five years in prison. All these imprisonments and prosecutions were for inciting hatred against an identifiable group. He was released on March 1, 2010. SOURCE: Wikipedia
