In 1833 Eugene Francois Vidocq was, as far as we can tell the worlds first private investigator. His business was called “Le Bureau des Renseignements Universels pour le commerce et l’Industrie” (“The Office of Universal Information For Commerce and Industry”). He hired hired ex-convicts to work for him, which makes a lot of sense. Official law enforcement tried many times to shut it down. In 1842, police arrested him in suspicion of unlawful imprisonment and taking money on false pretences after he had solved an fraud case. He was sentenced for five years with and a 3,000 Franc fine but the Court of Appeals released him. Vidocq is credited with having introduced record-keeping, criminology and ballistics to crime fighting He was also the first person to make plaster casts of shoe impressions, so bigfoot hunters everywhere have a lot to thank him for. He created indelible ink and unalterable bond paper.
