St. George Tucker was a Bermudian-born American lawyer, military officer and professor who taught law at the College of William & Mary. He strengthened the requirements for a law degree at the college, as he believed lawyers needed deep educations. He served as a judge of the General Court of Virginia and later on the Court of Appeals.
