German in origin, Dr. Fredrick Töben was raised in Australia as an Australian citizen, and speaks both English and German. Becoming interested in exonerating the German people from the anti-German racism of the Holocaust legend, he at first edited a revisionist journal called Truth Missions, which was later renamed Adelaide Institute Newsletter. He then broadened out to establish Australia's revisionist website, Adelaide Institute. He has personally visited the site of Auschwitz and burrowed under the ruins of the alleged gas chamber, being unable to find the four holes in the roof which were supposedly used to throw in gas pellets. He conducted regular dialogue with Exterminationists. Töben was arrested during an April 1999 visit with Prosecutor Klein in Mannheim, Germany, for a private discussion on the Holocaust laws in Germany, which make it mandatory to accept the entire Holocaust story. He was subsequently sentenced to 9 months imprisonment.
