Pinkerton National Detective Agency

Pinkerton National Detective Agency

Pinkerton Government Services, Inc., founded as the Pinkerton National Detective Agency, usually shortened to the Pinkertons, is a private security guard and detective agency established in the U.S. by Allan Pinkerton in 1850 and currently a subsidiary of Securitas AB. Pinkerton became famous when he claimed to have foiled a plot to assassinate president-elect Abraham Lincoln, who later hired Pinkerton agents for his personal security during the Civil War. Pinkerton's agents performed services ranging from security guarding to private military contracting work. Pinkerton was the largest private law enforcement organization in the world at the height of its power. At its height, the Pinkerton National Detective Agency employed more agents than there were members of the standing army of the United States of America, causing the state of Ohio to outlaw the agency due to fears it could be hired as a private army.

During the labor unrest of the late 19th and early 20th centuries, businessmen hired the Pinkerton Agency to infiltrate unions, supply guards, keep strikers and suspected unionists out of factories, as well as recruiting goon squads to intimidate workers. One such confrontation was the Homestead Strike of 1892, in which Pinkerton agents were called in to reinforce the strikebreaking measures of industrialist Henry Clay Frick, acting on behalf of Andrew Carnegie. The ensuing battle between Pinkerton agents and striking workers led to the deaths of 7 Pinkerton agents and 9 steelworkers. The Pinkertons were also used as guards in coal, iron, and lumber disputes in Illinois, Michigan, New York, Pennsylvania, and West Virginia as well as the Great Railroad Strike of 1877 and the Battle of Blair Mountain 1921. The organization was pejoratively called the "Pinks" by its opponents and victims.

The company now operates as Pinkerton Consulting and Investigations, a division of the Swedish security company Securitas AB, although its government division is still known as Pinkerton Government Services.
