Allan Pinkerton

Notorious agency of Scottish-American detective Allan Pinkerton broke strikes and disrupted labor efforts to unionize.

People best know this spy for creating the national agency. In 1849, people in Chicago first appointed Pinkerton. In the 1850s, he partnered with Chicago attorney Edward Rucker in forming the northwestern police agency, later known nationally and still in existence today as Pinkerton consulting and investigations, a subsidiary of Securitas Aktiebolag.

Business insignia of Pinkerton included a wide open eye with the caption, "We never sleep."

People posthumously published exploits of his agents, perhaps some ghostwritten for promotion.
