A number of years ago I was asked for help in finding information on someone who supposedly worked for the Pinkerton National Detective Agency, and in the process, I was surprised to discover that the Manuscript Division has some of the company records. Ever since then, every time I run across a mention of this company, I think of that collection.
Allan Pinkerton was born in Glasgow on August 25, 1819 and moved to the United States as a young man. After working for the Chicago police, he left to found Pinkerton National Detective Agency. He is credited with disrupting an assassination plot against President Lincoln and was even hired to “investigate” and gather military information in the South in the early days of the Civil War. His Union Intelligence Service was a precursor to the United States Secret Service. After his service in the war, he returned to the private sector and his company. Allan Pinkerton died July 1, 1884, the companyhe founded is still around doing pretty much what he did all those years ago.

Incidents of the war, group at Secret Service Department Headquarters, Army of the Potomac, Antietam, October 1862. Group of men, including Allan and William Pinkerton, and several Union Army officers.
If you want a better sense of what the firm actually did, a quick look though the finding aid on this collection is eye opening – if you will pardon the pun. There is the Criminal Case File, which has information on many crimes of the day. For example, there were the thefts at the Adams Express Co., forgeries at the Bank of England, the murders of Josephine Barnaby and William Lowe Rice, a robbery of the Bauman-Massa Jewelry Co., information from the investigation of the Molly Maguires, material on the Homestead Strike, etc. Even more tantalizing is the material on gangs and outlaws that became part of American folklore, such as Jesse James and the James family, the Younger family, the “The James-Younger Gang”, the William Barrett gang, Harvey “Kid Curry” Logan’s gang, and the Bass-Collins gang.

Antietam, Md. Allan Pinkerton, President Lincoln, and Maj. Gen. John A. McClernand. Alexander Gardner, October 3, 1862.
The Administrative File contains internal information, such as training manuals from the 1950’s, public relations and promotional material, material related to the American Bankers Association, and reward books from Denver, New Orleans, Kansas City and other locations. But it also has information on the firm’s activities including even more material related to the “Baltimore Plot” to assassinate Lincoln, other Civil War related activity, and. U.S. Secret Service correspondence.
If you want to read more, there are a number of articles in Chronicling America. There was one from 1895 in the Omaha Daily Bee that caught my eye because it related many anecdotes and included drawings based on photos from the Library’s collection that I featured in this post. The article was written by Cleveland Moffett who wrote True Detective Stories from the Archives of the Pinkertons, as well as another article in 1905. There were many other articles covering the firm’s exploits, including one written not long after Pinkerton died, another titled “King of the Sleuths,” which was a “study of the modern detective” featuring William Pinkerton; and lastly, one that featured Bob Pinkerton and a robbery of $40,000.
