Alan Pinkerton founded the Pinkerton Detective Agency in the 1850s. During the Civil War, it played a crucial role tracking Confederate spies, elevating its prominence as a force in law enforcement.
The Pinkertons infamously pursued infamous bank robbers Butch Cassidy and the Sundance Kid, though the duo eluded capture for years. The agency innovated techniques like the "Rogue's Gallery" criminal database, as agents McParland and Siringo attest. Eventually, Cassidy and the Sundance Kid fled to South America and were killed in a 1908 shootout.
The Pinkertons faced significant backlash for violently suppressing labor unions and strikes. Their actions in the Homestead Steel Strike of 1892 led to numerous deaths, further cementing their reputation as a private militia for corporate interests, according to reporter Robert Pinkerton.
Following the Steunenberg assassination trial involving accusations against agent McParland, Senator La Follette's congressional investigation in the 1930s revealed extensive labor spying by the agency. Amidst public outcry, Robert Pinkerton vowed to cease labor investigations.
The Pinkerton Detective Agency pioneered crime-fighting techniques like the "Rogue's Gallery" and fingerprinting, which were later adopted by the FBI. As the Bureau of Investigation grew under J. Edgar Hoover, it emerged as a major competitor to the Pinkertons' investigative business model.
To adapt, the Pinkertons shifted focus from investigations to corporate security contracts and specialized services, as outlined by agency materials. Founder William Pinkerton donated the agency's criminal photo collection, helping establish what became the FBI.
Former Pinkerton agent Dashiell Hammett drew from his experiences for novels like "The Maltese Falcon," creating iconic hard-boiled detectives inspired by agency operatives. While the agency pressured ex-agents like Charles Siringo, Hammett fictionalized the Continental Op to sidestep clashes.
After publicly vowing to cease labor spying amid pressure from Senator La Follette's findings, the agency suffered nearly 40% income losses. However, leadership changes, a World War II manufacturing security role, and embracing new technologies enabled recovery and transformation into a high-tech global security firm.
In 1999, the Pinkertons were purchased by Swedish conglomerate Securitas AB, cementing its new focus on cybersecurity for corporate clients worldwide.
1-Page Summary
The Pinkerton Detective Agency, founded by abolitionist Alan Pinkerton during the 1850s, became a significant force in law enforcement history, famously tracking Confederate spies during the Civil War and relentlessly pursuing iconic outlaws of the American West, including Butch Cassidy and the Sundance Kid.
Alan Pinkerton, with his strong background as an abolitionist, established the Pinkerton Detective Agency in the 1850s. During the Civil War, the agency played a critical role in tracking Confederate spies, elevating its stature as a prominent force in law enforcement.
The Pinkerton National Detective Agency is infamously known for its relentless pursuit of Butch Cassidy, whose real name was Robert Leroy Parker. He, alongside Harry Longabaugh, known as the Sundance Kid, became notorious for robbing banks and trains in the 1890s as part of the “Hole in the Wall Gang,” also called the Wild Bunch. This gang found refuge in the caverns of eastern Wyoming and evaded capture while committing numerous robberies.
After the gang stole a significant sum from a safe in 1899, the director of the Union Pacific Railroad, E.H. Harriman, hired the Pinkerton Agency, with a sizable reward of $10,000 per man, to bring the criminals to justice. Agents from the Denver office, led by James McParland, took up the task. Though McParland's agents, including Pinkerton detective Charles Siringo, deployed various innovative investigative techniques such as the "Rogue's Gallery" database of criminal profiles, the gang managed to elude their grasp for years.

The early history and notorious cases of the Pinkerton Detective Agency
The Pinkerton National Detective Agency faced significant backlash due to their active role in suppressing labor movements and their reputation as violent strike-breakers in American history.
The notoriety of the Pinkerton agency in the realm of labor disputes stems from multiple incidents.
Most infamously, during the Homestead Steel Strike of 1892, the Pinkertons' actions led to multiple deaths, which intensified public disdain towards them. Newspapers chronicled these events and noted that Robert Pinkerton, head of the agency, was particularly despised by organized labor— a sentiment linked to the Pinkerton agency’s role in labor conflicts.
The Pinkertons had become synonymous with violently breaking strikes and effectively acting as a private militia in service of corporate interests. This reputation solidified when their involvement in suppressing labor actions frequently resulted in violence.
The Pinkertons' practices of labor spying and their role in violent suppressions led to significant legal troubles and a tide of public criticism.
Following the controversial case of former Idaho Governor Frank Steunenberg's assassination, which saw a trial accusing union leaders of conspiracy, public sentiment soured against the agency. Clarence Darrow defended union leaders and accused Pinkerton agent James McParland of engineering a forced confession. Despite the acquittal of the union leaders, the trial and its aftermath cast a dark shadow over the Pinkertons, spurring protests and bitter criticisms from across the United States.
The Pinkertons' role in labor conflicts and their reputation for strike-breaking
The Pinkerton National Detective Agency, known for its innovative crime-fighting techniques, found itself in competition with the development of federal law enforcement agencies like the FBI. This rivalry ultimately influenced the growth of national criminal data and investigative procedures.
The Pinkertons had a profound impact on the development of criminal identification and investigative methods that were later refined and adopted by federal agencies.
The Pinkerton agency was instrumental in the development of early criminal databases. They created the "Rogue's Gallery," a catalog of mugshots and case histories that served as a foundational model for the FBI's criminal database. Moreover, their adaptation of fingerprinting techniques, which William Pinkerton acquired knowledge of during visits to Scotland Yard, was later incorporated by the FBI into their procedure.
Over time, the Bureau of Investigation, which later became known as the FBI, emerged as a formidable competitor to the Pinkerton agency. William Pinkerton contributed significantly to the developing federal system by donating his company's vast collection of criminal photographs to the National Bureau of Criminal Identification. This gesture helped establish the Criminal Identification Bureau that merged into the Bureau of Investigation. Nevertheless, the creation of the Bureau marked the start of a decline in the traditional investigative work that had been the Pinkerton's bread and butter, as the government took over criminal cases the Pinkertons used to handle.

The Pinkertons' competition with and influence on the development of federal law enforcement agencies like the FBI
Dashiell Hammett's career as a writer brought the gritty reality of detective work to the public through his iconic novels, drawing from his background as a former operative at the well-known Pinkerton Detective Agency.
Hammett joined the Pinkerton Detective Agency in 1915 at the age of 21. His work as an operative involved surveillance and stakeouts, primarily out of the Baltimore office, and later in Spokane, Washington, and San Francisco. Hammett's final Pinkerton assignment was to investigate the theft of gold coins from a docked passenger ship in San Francisco, a case that provided the basis for his later work, "The Maltese Falcon," which featured the private detective Sam Spade.
After leaving the Pinkerton agency in 1922, disillusioned with their strike-breaking work and to contend with his health issues from tuberculosis, Hammett turned to writing. The agency served as inspiration for the hard-boiled detective characters in his stories and novels, such as "Red Harvest" and "The Glass Key." His Pinkerton experiences informed the scenarios involving miners, mine bosses, strikers, and strike-breakers that his characters dealt with. He utilized a language that evoked the gritty realities of his detective past and avoided romanticizing the profession.
The Pinkerton agency was protective of its image and took legal action against former agent Charles Siringo to prevent him from publishing h ...
The career of writer Dashiell Hammett and his fictionalization of the Pinkerton agency
The Pinkerton agency experienced a significant transformation from its earlier role in labor spying to becoming a global corporate security firm. Changes in ownership and a new focus on high-tech services have marked its evolution into the 21st century.
The Pinkerton agency, once known for its labor espionage activities, publicly vowed to end these practices. Robert Pinkerton, during testimony, admitted that his company had provided labor spies to General Motors among others but declared they would cease such practices. The agency, however, returned to its roots in guarding corporate interests after federal agencies began taking over traditional law enforcement roles.
After retreating from labor espionage, the Pinkerton agency suffered significant financial consequences. In the late 1930s, the agency's income dropped nearly 40 percent, a stark indicator of the impact that moving away from espionage had on its bottom line.
The company managed to recover financially during World War II by shifting its focus to providing security for manufacturing plants which enabled it to bounce back from previous losses.
