From France to the United States
In 1833 Eugène François Vidocq, a French soldier, criminal and privateer, founded the first known private detective agency, “Le Bureau des Renseignements Universels pour le commerce et l’Industrie” (“The Office of Universal Information For Commerce and Industry”) and hired ex-convicts. 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 pretenses after he had solved an embezzlement case.
Vidocq later suspected that it had been a set-up. He was sentenced for five years with a 3,000-franc fine but the Court of Appeals released him. Vidocq is credited with having introduced record-keeping, criminology and ballistics to criminal investigation. He made the first plaster casts of shoe impressions. He created indelible ink and unalterable bond paper with his printing company. His form of anthropometrics is still partially used by French police. He is also credited for philanthropic pursuits – he claimed he never informed on anyone who had stolen for real need.
After Vidocq, the industry was born. Much of what private investigators did in the early days was to act as the police in matters that their clients felt the police were not equipped for or willing to do. A larger role for this new private investigative industry was to assist companies in labor disputes. Some early private investigators provided armed guards to act as a private militia.
In the United Kingdom, Charles Frederick Field set up an inquiry office upon his retirement from the Metropolitan Police in 1852. Field became a friend of Charles Dickens and the latter wrote articles about him. In 1862 one of his employees, the Hungarian, Ignatius Paul Pollaky, left him and set up a rival agency. Although little remembered today, Pollaky’s fame at the time was such that he was mentioned in various books of the 1870s and immortalized as “Paddington” Pollaky for his “keen penetration” in the 1881 comic opera, Patience.
In the United States, the Pinkerton National Detective Agency was a private detective agency established in 1850 by Allan Pinkerton. Pinkerton had become famous when he foiled a plot to assassinate then President-Elect Abraham Lincoln.
Pinkerton’s agents performed services which ranged from undercover investigations and detection of crimes to plant protection and armed security. It is sometimes claimed, probably with exaggeration, that at the height of its existence the Pinkerton National Detective Agency employed more agents than the United States Army. Allan Pinkerton hired Kate Warne in 1856 as a private detective, making her the first female private detective in America.
During the union unrest in the US in the late 19th century, companies sometimes hired operatives and armed guards from the Pinkertons. In the aftermath of the Homestead Riot, several states passed so-called “anti-Pinkerton” laws restricting the importation of private security guards during union strikes. The federal Anti-Pinkerton Act of 1893 continues to prohibit an “individual employed by the Pinkerton Detective Agency, or similar organization” from being employed by “the Government of the United States or the government of the District of Columbia.”
Pinkerton agents were also hired to track western outlaws Jesse James, the Reno brothers, and the Wild Bunch, including Butch Cassidy and the Sundance Kid. The Pinkerton agency’s logo, an eye embellished with the words “We Never Sleep,” inspired the term “private eye.”
It was not until the prosperity of the 1920s that the private investigator became a person accessible to the average American. With the wealth of the 1920s and the expanding of the middle class came the need of middle America for private investigators.
Since then, the private detective industry has grown with the changing needs of the public. Social issues like infidelity and unionization have impacted the industry and created new types of work, as has the need for insurance and, with it, insurance fraud, criminal defense investigations and the invention of low-cost listening devices.
As the world evolved so too has the job of private investigation. Increasingly the job relies upon teamwork and sophisticated electronic devices. More than a working knowledge of computers is required and in many cases that specialist assignment on the team is essential.
Increasingly, modern PIs prefer to be known as “professional investigators” or Licensed Private Investigators (LPI’s) rather than “private investigators” or “private detectives”. This is a response to the image that is sometimes attributed to the profession and an effort to establish and demonstrate the industry to be a proper and respectable profession.
An undercover investigator, undercover detective, or undercover agent is a person who conducts investigations of suspected or confirmed criminal activity while impersonating a disinterested third party. Undercover investigators often infiltrate a suspected insurgent group, posing as a person interested in purchasing illegal goods or services with the ultimate aim of obtaining information about their assigned target.
Many undercover investigators carry hidden cameras and recorders strapped to their bodies to help them document their investigations. The period of the investigation could last for several months or, in some extreme cases, years. Due to the dangerous nature of the job, their real identities are kept secret throughout their active careers.
