The Diary of Anne Frank was first published in 1947 in the Netherlands and became an instant bestseller. It has been translated into many languages of the world, reprinted many times and sold to the public as an original, handwritten by a Jewish girl from Amsterdam. Performances and ballets were staged based on the diary, and it was filmed in Hollywood, and the film was a huge success. Anne Frank's diary is an official international cultural property - it is included in the UNESCO Memory of the World heritage list, and in 2009, on the Onepoll.com portal, it was included in the TOP 10 list of books “that inspire readers.” This work was repeatedly published in Russian. However, in the genre of memoirs and diaries, there are many literary hoaxes that were passed off as genuine memories or descriptions of the lives of various famous people - just remember the “memoirs” of Eva Braun, Hess, Schellenberg, Müller, Eichmann or various versions Hitler's infamous "table conversations" and diaries. But one of the most sensational revelations is related to the book “The Diary of Anne Frank.”
