A great deal of reliable information is available about Anne Frank and her diary. But sometimes, on the Internet and elsewhere, lies are spread about the diary. There are books and pamphlets in circulation in which you can read that the diary is a forgery that was written by people other than Anne Frank herself. There are websites where it is claimed that parts of the diary are written in ballpoint pen.
The Anne Frank House regularly takes successful legal action against attacks on the authenticity of the diary. Anyone who is nevertheless confronted with lies about the diary can find the most important facts about its authenticity, in question and answer form (pdf), on this page.
Over the years a number of people have tried to spread the claim that the diary of Anne Frank is a forgery. Until his death, Otto Frank carried out legal actions against these "deniers". In 1979 – he was then 90 years old – he commented on this: "At the moment there are four court cases in West Germany, two in Hamburg and two in Frankfurt, concerning accusations that the diary is a forgery. I fought against this in 1961 and won, but the same accusations are still being expressed, and I have to fight against them over and over again." After his death in 1980 this task is taken over by the Anne Frank House and the Anne Frank Fonds.
Holocaust denier Faurisson visits Otto Frank
In October 1993 Fritzi Frank-Markowitz was interviewed by Wouter van der Sluis, a researcher and filmmaker from the Anne Frank House. Fritzi Frank was the widow of Otto Frank. She died in 1998. In the interview she talks about the visit of Robert Faurisson, a notorious Holocaust denier. He denies the existence of gas chambers, for example, and disputes the authenticity of the diary of Anne Frank. But according to Fritzi Frank, when he examined the diary he said; “It’ll be very difficult to prove that the diary is a forgery.”
In order to clarify the different editions of Anne’s diary, in 1986 the NIOD publishes the critical edition which differs from the bookstore version. This edition includes the three versions of the diary: the original diary, the version Anne Frank rewrote and the version compiled by Otto Frank which was published in 1947 by Contact.
