Little is recorded locally about William Pinkerton's personal biography, but his significance to Dundee's history is indirect and familial: the town that his father Allan called home in the 1850s was the seedbed from which the entire Pinkerton enterprise grew.
Known Activities
William Pinkerton held responsibility for the Pinkerton Detective Agency's operations across the western United States as of 1907, at which time the agency employed over 1,500 people and maintained branches in major cities across the United States and Canada, with agents also active in Europe.

Following the death of his brother Robert Allan Pinkerton in September 1907, William is believed to have assumed a still more prominent role in the agency's leadership, though the precise organizational changes that followed are not documented in local sources.
The agency that William helped lead had by 1907 accumulated a formidable — and contested — reputation. According to the Italian-language San Francisco newspaper L'Italia, Pinkerton forces were engaged in a violent confrontation with striking workers at Carnegie steel facilities in Pittsburgh in 1894. The account describes strikers of various nationalities deploying two Maxim cannons against agency forces, resulting in what the paper characterized as a bloody combat ending in an agency victory.

Family Background and Dundee Connection
William Pinkerton's father, Allan Pinkerton, emigrated from Scotland and settled in Dundee, Illinois approximately fifty years before 1907 — that is, around 1857 — though some accounts place his arrival slightly earlier. (Source: litalia_1907-09-14_image5) Dundee at that time was a small frontier settlement located roughly thirty miles northwest of Chicago, reportedly troubled by horse thieves, cattle rustlers, and counterfeiters.
Allan Pinkerton was by trade a cooper — a barrel maker — but his efforts to combat local criminal activity drew community notice, and he was reportedly elected sheriff of Dundee before eventually relocating to Chicago, where he established what became the Pinkerton National Detective Agency. (Source: litalia_1907-09-14_image5) The Bisbee Daily Review corroborates that Allan Pinkerton was a Scotsman and that he founded the Pinkerton National Detective Agency, with its headquarters in Chicago, and further notes that he served as chief of intelligence during the Civil War.

William and his brother Robert were products of that trajectory: sons of a man who had found his footing in a small Illinois river town before building one of the most powerful private law-enforcement organizations in American history. Notably, the Bisbee Daily Review records that Robert Allan Pinkerton was born in Dundee, Illinois in 1848, making Dundee not only the place where Allan Pinkerton began his detective career but also the literal birthplace of at least one of the sons who carried that enterprise forward.

Robert Allan Pinkerton, William's brother, served as principal of the Eastern branch of the Pinkerton detective service. The Bisbee Daily Review described him as "the Chesterfield of detectives," characterizing his method as one of scheming and laying traps for criminals rather than solely hounding them. He was also noted for having worked on several major crimes in the Southwest. (Source: bisbee_daily_review_1907-08-24_image8)
