The Culper Ring was a network of spies active during the American Revolutionary War, organized by Major Benjamin Tallmadge and General George Washington in 1778 during the British occupation of New York City. The name "Culper" was suggested by George Washington and taken from Culpeper County, Virginia. The leaders of the spy ring were Abraham Woodhull and Robert Townsend, using the aliases of "Samuel Culper Sr." and "Samuel Culper Jr.", respectively; Tallmadge was referred to as "John Bolton".

Benjamin Tallmadge was an American military officer, spymaster, and politician. He is best known for his service as an officer in the Continental Army during the American Revolutionary War. He acted as leader of the Culper Ring during the war, a celebrated network of spies in New York where major British forces were based. He also led a successful raid across Long Island that culminated in the Battle of Fort St. George. After the war, Tallmadge was elected to the US House of Representatives as a member of the Federalist Party.
