History of the Private Investigator

In 1833 Eugene Francois Vidcoq, a French ex-criminal, founded one of the first private detective agencies, Le bureau des renseignments (Office of Intelligence) where he oversaw the work of other detectives, many ex-criminals like himself. He’s credited with having introduced record-keeping, criminology, and ballistics to criminal investigation. He also created indelible ink and unalterable bond paper with his printing company. Apparently, he had an altruistic bent as he claimed he never informed on anyone who had stolen for real need.

With Vidocq, the private investigator was born. As the industry evolved, clients often hired PIs to act in law enforcement capacities, especially in matters they were not equipped for or willing to do. This led to PI agencies sometimes performing like private militia and assisting companies in labor disputes.

Such an agency was the Pinkerton National Detective Agency in the United States. It was established in 1850 by Allan Pinkerton, whose claim to fame was foiling a plot to assassinate then President-Elect Abraham Lincoln.

In an era with many law enforcement personnel openly associating with criminals sharing their illegal profits, Pinkerton stood out by promising that his agents would not only produce results, but always act with the highest ethics. He promised to:

Accept no bribes
Never compromise with criminals;
Partner with local law enforcement agencies, when necessary
Refuse divorce cases or cases that initiated scandals of clients
Turn down reward money (his agents were paid well)
Never raise fees without the client’s pre-knowledge, and
Apprise clients on an ongoing basis.

It’s remarkable how many of the above ethical standards are mirrored in many PIs’ standards today (such as regularly apprising clients, partnering with law enforcement, and raising fees only with clients’ knowledge). It’s also amusing to read how Pinkerton’s men refused divorce cases considering today many PIs specialize in marital investigations.

The term “private eye” is from the Pinkerton agency’s logo, an eye surrounded with the words “We Never Sleep.”

In his memoirs, Pinkerton credited two specific agents (one female) for helping establish the firm’s reputation for efficiency and honor: Timothy Webster and Kate Warne (the first female detective in the U.S.).

By the 1920s, due to the expanding middle class in America, the private investigator became better known to the average citizen. Since then, the PI industry has continued to grow as it fills the needs of the public (who retain PIs to work on cases like infidelity, fraud, and criminal defense investigations). Licensing requirements, with criteria a PI must meet, have also been regulated in most states in the U.S. Additionally, professional organizations (regional, national, and international) combined with good business practices have cast the PI career in a more respected light versus its outdated, fictional reputation as the wrinkled trench coat, fallen-from-grace Sam Spade figure found in books and film.
