History of Handwriting Analysis~

Handwriting analysis is basically a comparison between two or more documents and determining whether or not the same person wrote both documents. Throughout the years, handwriting analysis has gotten more accurate and police are sometimes able to use it as a valid clue. Although, in the 1980's handwriting analysis was not very authentic because a man named Konrad Kujau was able to trick all by forging a few diaries he stated was written by Hitler. Kujau reported to the police that he had found a lost diary of Adolf Hitler in an airplane wreckage after World War II. After police compared the diary with known exemplars written by Hitler, they stated that the diary was truly written by Hitler and Kujau received 2.3 million dollars. It was not until years later was Kujau identified as a liar, for he forged the diaries and the 'exemplars'. Kujau was caught because apparently, the paper Kujau used had a special ingredient that was not used in paper until 1954, whereas Hitler passed away in 1945.
