Faurisson interviewed Otto Frank in researching the piece, though much of what Faurisson asserted Frank had said was later contradicted by Frank himself. Faurisson's writing on the subject first came into the spotlight during a court case between Otto Frank and Heinz Roth, a publishing-house owner responsible for the circulation of various neo-Nazi writings, including several publications impugning the authenticity of Anne Frank's diary; Faurisson's writing on the subject was entered into the court record as an expert opinion in defense of Roth. The 1978 finding of the court was that Roth must refrain from publishing any further reading material claiming the diary was a fraud.
