The History of Criminalistics. Dactyloscopy
On August 22, 1911 Leonardo da Vinci's masterpiece Mona Lisa was stolen right off the wall of the Louvre. There were no witnesses and the perpetrator didn't leave any traces except a clear fingerprint, which later led to the capture of the thief. A police officer, William Herschel, was the first to draw attention to the uniqueness of papillary pattern on human fingers and palms.
