Allan Pinkerton's detective memoir made 'pinkerton' a word for private investigator

the gist

Allan Pinkerton, a Scottish-born barrel maker who emigrated to America, founded the world's largest private detective agency in 1850. His agency's eye logo and motto 'We never sleep' are said to have inspired the term 'private eye'. It guarded Abraham Lincoln on his journey to the capital in 1861, and later worked on railroads and against strikes. Thirty Years a Detective, published in 1884, the year he died, is a 600-page collection of stories about crime and criminals. By then his name was so famous that 'a pinkerton' was slang for a private investigator.

so what

The book helped create the image of the detective in popular culture, and the agency is remembered both for solving crimes and for breaking strikes.

fun fact

Pinkerton wrote at least a dozen books, mostly based on his cases.
