Pinkerton National Detective Agency Pinkerton guards escort strike-breakers in Buchtel, Ohio, 1884The Pinkerton National Detective Agency, usually shortened to the Pinkertons, was a private U.S. security guard and detective agency established by Allan Pinkerton in 1850. Pinkerton had become famous when he 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. 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 out as a private army or militia.[citation needed] During the labor unrest of the late 19th century, businessmen hired Pinkerton agents to infiltrate unions, and as guards to keep strikers and suspected unionists out of factories. The best known such confrontation was the Homestead Strike of 1892, in which Pinkerton agents were called in to enforce the strikebreaking measures of Henry Clay Frick, acting on behalf of Andrew Carnegie, who was abroad; the ensuing conflicts between Pinkerton agents and striking workers led to several deaths on both sides. The Pinkertons were also used as guards in coal, iron, and lumber disputes in Illinois, Michigan, New York, and Pennsylvania, as well as the railroad strikes of 1887. 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. The organization was pejoratively called the "Pinks" by the outlaws and opponents.
