The History of the Private Investigator
Famous fictional Private detectives rely on powers of deduction/rationalization and educated consideration to solve crimes. These characters have for ages been a staple of detective mystery crime fiction, specifically in detective novels and short stories emerge Britain and written through the "Golden Age of Detective Fiction" (1920s-1930s). They are generally popularized as individual characters as opposed to parts of the fictional work in which they appear.
Among the first famous Private Investigators in fiction was Arthur Conan Doyle's Sherlock Holmes. Others included Miss Marple, Lord Peter Wimsey, Poirot and Jim Rockford. It had not been until the prosperity from the 1920s that the Private Investigator became accessible to the average citizen.
In Great Britain, it's been suggested that the Private Investigator was operating a long time before the Metropolitan Police was formed more than 100 years ago. The organization of the Police Force might have been hastened by the unscrupulous activities of some of these Private Investigators. While the ethics and character of several of those earlier Private Investigators was open to criticism, today's Private
Investigator is generally honest, efficient, well-educated and aware of his moral and legal responsibilities.
The initial Private Investigation agency was founded in 1833 by Eugene Vidocq, a French soldier and privateer. While he hired ex-cons, law enforcement tried closing down his Office of Intelligence many times. Vidocq, despite some suspicious practices, is credited with introducing record-keeping, criminology and ballistics to criminal investigations. He made the first plaster casts of shoe impressions, created indelible ink as well as an unalterable bond paper. In the US, the Pinkerton National Detective Agency was a detective agency, established in 1850 by Allan Pinkerton. Pinkerton had become famous when he foiled a plot to assassinate then President-Elect Abraham Lincoln. Through the height of its existence, the Pinkerton Detective Agency had more agents compared to the standing army of the us of America, causing the condition of Ohio to outlaw the business, due to the possibility of its being hired out as a "private army" or militia. The agency's logo, a watch embellished with the words "We Never Sleep" inspired the word "private eye.
Since then the individual detective industry has exploded with the changing needs from the public. Social issues like infidelity and unionization have impacted the industry and created new types of work, as gets the need for insurance, and with it insurance fraud, criminal investigations, the invention of inexpensive listening devices plus more.
