The Early Days of Private Investigation in America

Allan Pinkerton started the first private detective agency in America in 1849, and it was his work with the Underground Railroad that first got him interested in private investigation.

Pinkerton and his team of investigators were responsible for tracking down runaway slaves and helping them to escape to freedom.

As an abolitionist, he and his ring of spies infiltrated slave plantations and provided intelligence to the Underground Railroad on the best routes to freedom.

Although Pinkerton’s work was dangerous, he was incredibly successful in helping slaves escape to freedom.

After the Civil War ended, Pinkerton’s detective agency began to take on other cases.

He and his team investigated everything from counterfeiters to bank robbers, and they quickly gained a reputation for being some of the best investigators in the country.

The Golden Age of Private Investigation

The 1920s marked the golden age of private investigation in America.

This was due to a number of factors, including the rise of Hollywood and its fascination with crime, as well as the advent of new technologies like the telephone and the radio.

Private investigators could use these new technologies to their advantage, and they quickly became known for their innovative techniques.

One of the era’s most famous fictional private investigators was Sam Spade, who Humphrey Bogart portrayed in the 1941 film “The Maltese Falcon.”

Spade was a tough-talking private detective who wasn’t afraid to break the law to get results.

While he was fictional, there were many real-life private investigators who shared Spade’s no-nonsense attitude.

In addition to taking on cases from Hollywood stars and other celebrities, private detectives also began to take on more dangerous jobs during the 1920s.

They began to specialize in areas like industrial espionage and undercover work, and they were often willing to take on cases that no one else was willing to do.

The private detective agencies of the 1920s were a diverse group, and each one had its own unique approach to investigation.

Some agencies were run by former police officers, while others were made up of ex-military men or former con artists. But despite their differences, all of these agencies shared a common goal – solving crimes and getting results.
