Source Bundes Kriminal Amt forensic report, 1980 "Ay, Tone. You know Anne Frank's diary was written with ballpoint pen? Dey didn't even have dose yet. Dats some Leonardo Da Vinci shit." 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 post-war 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.
