Charles Willson Peale (1741-1827) gained his initial experience in portraiture by using members of his family as subjects. As his talents expanded, he visited and developed patronage in New England, Maryland, and Virginia, as well as in London, England, finally settling in Philadelphia on the eve of active military service and the creation of his officer portrait gallery. By the close of the century he had painted many of the distinguished figures of the young nation, among them Maj. Gen. Arthur St. Clair who was completing his first military service in the Revolutionary War. The portrait is reproduced from the Independence National Historical Park Collection in Philadelphia.
