George Mason V was an American planter, businessman, and militia officer. Mason was the eldest son of United States patriot, statesman, and delegate from Virginia to the U.S. Constitutional Convention, George Mason IV and his wife Ann Eilbeck. He received his early education from private tutors at Gunston Hall and was given Lexington plantation on Mason's Neck by his father in 1774. In 1775, he named his plantation to commemorate the Battle of Lexington in Massachusetts.

George Mason was an American planter, politician, Founding Father, and delegate to the U.S. Constitutional Convention in Philadelphia in 1787, where he was one of three delegates who refused to sign the Constitution. His writings, including substantial portions of the Fairfax Resolves of 1774, the Virginia Declaration of Rights of 1776, and his Objections to this Constitution of Government (1787) opposing ratification, have exercised a significant influence on American political thought and events. The Virginia Declaration of Rights, which Mason principally authored, served as a basis for the United States Bill of Rights, of which he has been deemed a father.
