William J. Burns International Detective Agency

The William J. Burns International Detective Agency was a private detective agency in the United States, which was operated by William J. Burns. It was headquartered in Briarcliff Manor, New York from 1969 to 1983.

The Burns Agency was hired to track down Industrial Workers of the World (IWW) organizers in the aftermath of the Wheatland Hop Riot.

Burns agents infiltrated the Industrial Workers of the World during an organizing drive in the copper mines of Arizona. Activities included issuing fake IWW membership cards, infiltrating the workforce, spying, and intercepting the mail of organizers.

Agents of the Burns Detective Agency were hired to "investigate" jurors in a federal trial of Harry F. Sinclair in November 1927. Sinclair hired William J. Burns to have 14 agents follow the jurors, and produce daily reports on their activities. The arrangement resulted in a mistrial. In a new hearing, Sinclair claimed that he was concerned about the welfare of the jurors. Sinclair was convicted on corruption charges and sentenced to six months in jail. William J. Burns was sentenced to 15 days' imprisonment, and Burns' son, William Sherman Burns, was ordered to pay a $1,000 fine. The Supreme Court later reversed William J. Burns' conviction.
