Josef Ginsburg (also known as Joseph Ginsberg; pen name Joseph G. Burg or J.G. Burg) was a Jewish revisionist author of many books as well as many shorter writings and two documentary interviews with Ernst Zündel. He was the chief Jewish advisor, mentor and Zündel witness in the 1988 trial of the Ernst Zündel's Holocaust trials.
He testified that he after the end of the war in 1945 had visited Auschwitz and had also visited Majdanek, had spoken to hundreds of people who had serviced and operated the crematoria, and had concluded that no homicidal gas chambers existed and that there had been no plan to exterminate the Jews of Europe.
