George Mason (1725-1792), a Virginia gentleman and close friend of George Washington, lived at Gunston Hall on the Potomac River in Fairfax County, Virginia. He occasionally served as the Fairfax County legislative representative and opposed British efforts to limit American rights. In 1769 he and Washington organized a non-importation agreement to protest the Townshend duties. In 1776 he drafted the Virginia Declaration of Rights, which would become the model for the Federal Constitution's Bill of Rights. Mason was a delegate to the Federal Constitutional Convention in 1787.
