Allan Pinkerton (1819-1884) was born in Scotland and immigrated to the United States in 1842. Settling in the Chicago area, his first career was as a cooper. While wondering in the woods looking for wood to make barrel staves, he came across some counterfeiters and helped in their arrest. That led to Pinkerton being appointed as police detective in Cook County, Illinois, and later forming his own company--the Pinkerton National Detective Agency. Pinkerton produced numerous books based on his work and that of his agents. While the books no doubt reflect his views, many historians believe he used a ghostwriter.
