In 1980, because of a lawsuit in a German court, the German state forensic bureau, the Bundes Kriminal Amt [BKA], forensically examined the original "diary" manuscript. Their analysis determined that "significant" portions of the work were written with a ballpoint pen. Since ballpoint pens were not available before 1951, portions of the work were added well after the war (Anne Frank died in March 1945).
The BKA also determined that none of the "diary" handwriting matched known examples of Anne's handwriting. Earlier handwriting experts had determined that all of the writing in the "diary" was by the same hand. Therefore, the entire "diary" was a postwar fake.
The true author of the diary was Jewish novelist Meyer Levin, who demanded and was awarded $50,000 in payment for his work in a court action against Anne's father, Otto Frank.
Article #1 : "The Anne Frank Diary Fraud" by Brian Harring
Article #2: "Is The Diary of Anne Frank genuine?" by Robert Faurisson
Felderer published a book showing that the Anne Frank diary was a hoax; his research included examining the building where the Anne Frank Museum was located today, samples of the girl's handwriting and the internal contradictions within the diary itself. Felderer wrote to Otto Frank, Anne Frank's father, requesting the opportunity to examine the actual handwritten diary. This request was denied. Felderer suggested in his book that an analysis of the diary ink should be made to determine authenticity; this was later done on part of the manuscript in a West German court proceeding. This analysis found that certain parts of the diary were written in ball-point pen and therefore must have been written after the war since ball-point pens were not sold during the war. Although Felderer was investigated in 1979 by the Swedish Attorney General concerning this book, no cause for any charge was found. Zündel was aware of the book and the investigation.

The truth about the Anne Frank Diary was first revealed in 1959 by the Swedish journal Fria Ord. It established that the Jewish novelist Meyer Levin had written the dialogue of the "diary" and was demanding payment for his work in a court action against Otto Frank. A condensation of the Swedish articles appeared in the American Economic Council Letter, April 15th, 1959, as follows: "History has many examples of myths that live a longer and richer life than truth, and may become more effective than truth. "The Western World has for some years been made aware of a Jewish girl through the medium of what purports to be her personally written story, Anne Frank's Diary. Any informed literary inspection of this book would have shown it to have been impossible as the work of a teenager.
"A noteworthy decision of the New York Supreme Court confirms this point of view, in that the well known American Jewish writer, Meyer Levin, has been awarded $50,000 to be paid him by the father of Anne Frank as an honorarium for Levin's work on the Anne Frank Diary."
Mr. Frank, in Switzerland, has promised to pay to his race kin, Meyer Levin, not less than $50,000 because he had used the dialogue of Author Levin just as it was and "implanted" it in the diary as being his daughter's intellectual work." Further inquiries brought a reply on May 7th, 1962 from a firm of New York lawyers, which stated: "I was the attorney for Meyer Levin in his action against Otto Frank, and others. It is true that a jury awarded Mr. Levin $50,000 in damages, as indicated in your letter. That award was later set aside by the trial justice, Hon. Samuel C. Coleman, on the ground that the damages had not been proved in the manner required by law. The action was subsequently settled while an appeal from Judge Coleman's decision was pending.
-Did Six Million Really Die? by Richard Harwood
The 15-year-old girl and her father, Otto Frank, were deported from the Netherlands to Auschwitz in September 1944. Several weeks later, in the face of the advancing Soviet army, Anne was evacuated along with many other Jews to the Bergen-Belsen camp, where she died of typhus in March 1945.
Her father came down with typhus in Auschwitz and was sent to the camp hospital to recover. He was one of thousands of sick and feeble Jews who were left behind when the Germans abandoned the camp in January 1945, shortly before it was overrun by the Soviets. He died in Switzerland in 1980. If the German policy had been to kill Anne Frank, neither she, nor her father and sister (along with many other Jews), would not have "survived" Auschwitz. "As tragic as it was," said Weber, "their fate cannot be reconciled with the extermination story."
