William Irvine was an Irish-American physician, soldier, and statesman from Carlisle, Pennsylvania. He practiced medicine as a ship's surgeon for the Royal Navy before he sympathized with the American Revolution and fought against the British during the American Revolutionary War. As tensions escalated between the American colonies and the British government during the 1770s, Irvine sympathized and allied himself with the revolutionary cause. He subsequently served as a brigadier general in the American Revolutionary War and served in the western theater. After the war he served in the Continental Congress, and later played an active role in ending the Whiskey Rebellion in Pennsylvania. He also served one term in Congress representing Pennsylvania, and was also active in the state's other public affairs.

William Crawford was an American military officer and surveyor who worked as a land agent alongside George Washington while Washington was a teenager. Crawford fought in the French and Indian War, Lord Dunmore's War and the American Revolutionary War arising to the rank of Colonel. In 1782, his unit was attacked, and while he and his surgeon escaped for less than one day, Crawford was eventually captured where he was tortured and burned at the stake by Crawford's former soldier turned British agent, Simon Girty, and Captain Pipe, a Chief of the Delaware Nation.
