Pinkerton, founded as the Pinkerton National Detective Agency, is a private security guard and detective agency established in the United States by Scotsman Allan Pinkerton in the 1850s and currently a subsidiary of Securitas AB.[1] Pinkerton became famous when he claimed to have foiled a plot to assassinate president-elect Abraham Lincoln, in 1861. Lincoln later hired Pinkerton agents to conduct espionage against the Confederacy and act as his personal security during the Civil War.[2][3] The Pinkerton National Detective Agency hired women and minorities from its founding, a practice uncommon at the time, as they were useful as spies.[4] At the height of their power, the Pinkerton Detective Agency was the largest private law enforcement organization in the world.[5]

Following the Civil War, the Pinkertons began conducting operations against organized labor. Since the late 1860s till today,[6] businesses have hired the Pinkerton Agency to infiltrate unions, supply guards, keep strikers and suspected unionists out of factories, and recruit goon squads to intimidate workers.[7] During the Homestead Strike of 1892, Pinkerton agents were called in to reinforce the strikebreaking measures of industrialist Henry Clay Frick, who was acting on behalf of Andrew Carnegie, the head of Carnegie Steel.[8] Tensions between the workers and strikebreakers erupted into violence which led to the deaths of three Pinkerton agents and nine steelworkers.[9][10] During the late nineteenth century, the Pinkertons were also hired as guards in coal, iron, and lumber disputes in Illinois, Michigan, New York, Pennsylvania, and West Virginia. Pinkertons were also involved in other strikes such as the Great Railroad Strike of 1877 and the Battle of Blair Mountain in 1921.

During the twentieth century, Pinkerton rebranded itself into a personal security and risk management firm. The company has continued to exist in various forms through to the present day, and is now a division of the Swedish security company Securitas AB, operating as "Pinkerton Consulting & Investigations, Inc. d.b.a. Pinkerton Corporate Risk Management".[11] The former Government Services division, PGS, now operates as "Securitas Critical Infrastructure Services, Inc.".[12]

Origins[edit]

In the 1850s, Allan Pinkerton, a Scottish immigrant met Chicago attorney Edward Rucker in a local Masonic Hall. The two men formed the North-Western Police Agency, later known as the Pinkerton Agency.[13][14][15] Pinkerton used his skills in espionage to attract clients and begin growing the agency.

Historian Frank Morn writes: "By the mid-1850s a few businessmen saw the need for greater control over their employees; their solution was to sponsor a private detective system. In February 1855, Allan Pinkerton, after consulting with six midwestern railroads, created such an agency in Chicago."[16]

Among the business's early operations was to safely deliver the newly elected President of the United States Abraham Lincoln to Washington, D.C., in light of an assassination threat. Pinkerton detective Kate Warne was assigned and successfully delivered Lincoln to the U.S. capital city through a series of disguises and related tactics that required her to stay awake throughout the entire long journey. As a result of the public notoriety of this success, the business adapted an open eye as its logo and the slogan, "We never sleep."[17]

US Government Contractor[edit]

In 1871, Congress appropriated $50,000 (about equivalent to $1,131,000 in 2021) to the new Department of Justice to form a sub-organization devoted to "the detection and prosecution of those guilty of violating federal law." The amount was insufficient to fashion an internal investigating unit, so they contracted out the services to the Pinkerton National Detective Agency.[18]

However, as news leaked about the Pinkerton's involvement in strikebreaking became public knowledge, lawmakers began pushing against the government contracts with the Pinkertons.[19] The Pinkertons reached their zenith in the 1870s and 80s which saw them frequently engage in violent crackdowns against striking workers. The most notable example of this was the involvement of the Pinkertons in the Great Railroad Strike of 1877. However it was the confrontation in Homestead, Pennsylvania that lead to a national outcry against the Pinkerton Detective Agency.[20] Following the strike, Congress took swift action against the Pinkertons and passed the Anti-Pinkerton Act in 1893, which severely curtailed the relationship between the federal government and the agency. The act states that, "individual employed by the Pinkerton Detective Agency, or similar organization, may not be employed by the Government of the United States or the government of the District of Columbia."[21]

Chicago "Special Officers" and watchmen[edit]

  • July 27, 1877: J. J. White, who had been hired as a "Special Officer" during a strike, was shot and killed.[22]
  • July 19, 1919: Hans Rassmuson, Special Officer, was shot and killed.[23]
  • March 12, 1924: Frank Miller, Pinkerton Watchman, was shot and killed.[24]

Molly Maguires[edit]

In the 1870s, Franklin B. Gowen, then president of the Philadelphia and Reading Railroad, hired the agency to "investigate" the labor unions in the company's mines. A Pinkerton agent, James McParland, using the alias "James McKenna", infiltrated the Molly Maguires, a 19th-century secret society of mainly Irish-American coal miners, leading to the downfall of the labor organization.

The incident inspired Arthur Conan Doyle's Sherlock Holmes novel The Valley of Fear (1914–1915). A Pinkerton agent also appears in a small role in "The Adventure of the Red Circle", a 1911 Holmes story. A 1970 film, The Molly Maguires, was loosely based upon the incident as well.

Homestead Strike[edit]

On July 6, 1892, during the Homestead Strike, 300 Pinkerton agents from New York and Chicago were called in by Carnegie Steel's Henry Clay Frick to protect the Pittsburgh-area mill and strikebreakers. This resulted in a firefight and siege in which 16 men were killed, and 23 others were wounded. Following the confrontation the Governor of Pennsylvania, Robert E. Pattinson mobilized state law enforcement and the National Guard. Private and government forces broke the strike and workers returned to the steel mill.[25]

The strike,dubbed "The Battle of Homestead" by local media ignited a firestorm around the United States.[26] Americans were outraged at the conduct of the Pinkertons and how strikers were treated. The Homestead Strike of 1892 is regarded as a turning point in American labor history and prompted Congress to begin a crackdown on the Pinkertons.[27]

As a legacy of the Pinkertons' involvement, a bridge connecting the nearby Pittsburgh suburbs of Munhall and Rankin was named Pinkerton's Landing Bridge.

Steunenberg murder and trial[edit]

Harry Orchard was arrested by the Idaho police and confessed to Pinkerton agent James McParland that he assassinated former Governor Frank Steunenberg of Idaho in 1905. Orchard testified (unsuccessfully), under threat of hanging,[28] against Western Federation of Miners president Big Bill Haywood, naming him as having hired the hit. With a stirring defense by Clarence Darrow, Haywood and the other defendants of the WFM were acquitted in a nationally publicized trial. Orchard received a death sentence, but it was commuted.[29]

Outlaws and competition[edit]

Pinkerton agents were hired to track western outlaws Jesse James, the Reno Gang, and the Wild Bunch (including Butch Cassidy and the Sundance Kid). On March 17, 1874, two Pinkerton Detectives and a deputy sheriff, Edwin P. Daniels,[30] encountered the Younger brothers (associates of the James–Younger Gang); Daniels, John Younger, and one Pinkerton agent were killed. In Union, Missouri, a bank was robbed by George Collins, aka Fred Lewis, and Bill Randolph; Pinkerton Detective Chas Schumacher trailed them and was killed. Collins was hanged on March 26, 1904, and Randolph was hanged on May 8, 1905, in Union. Pinkertons were also hired for transporting money and other high-quality merchandise between cities and towns, which made them vulnerable to outlaws. Pinkerton agents were usually well paid and well armed.

G.H. Thiel, a former Pinkerton employee, established the Thiel Detective Service Company in St. Louis, Missouri, a competitor to the Pinkerton agency. The Thiel company operated in the U.S., Canada, and Mexico.

Modern era[edit]

Due to its conflicts with labor unions, the word Pinkerton continues to be associated by labor organizers and union members with strikebreaking.[31] Pinkertons diversified from labor spying following revelations publicized by the La Follette Committee hearings in 1937,[32] and the firm's criminal detection work also suffered from the police modernization movement, which saw the rise of the Federal Bureau of Investigation and the bolstering of detective branches and resources of the public police. With less of the labor and criminal investigation work on which Pinkertons thrived for decades, the company became increasingly involved in protection services, and in the 1960s, even the word "detective" disappeared from the agency's letterhead.[33] The company now focuses on threat intelligence, risk management, executive protection, and active shooter response.

In 1999, the company was bought by Securitas AB, a Swedish security company, for $384 million,[34] followed by the acquisition of the William J. Burns Detective Agency (founded in 1910), longtime Pinkerton rival, to create (as a division of the parent) Securitas Security Services USA. Today, the company's headquarters are located in Ann Arbor, Michigan.[35]

The Baltimore branch, where Hammett first worked, was housed in the Continental Trust Building; the Pinkerton agency was not named. Hammett also worked in the San Francisco office, thus many of the Op stories were set in that city. They were published in Black Mask magazine from 1923 to 1930.
