William Lee, also known as Billy or Will Lee, was an American slave and personal assistant of George Washington. He was the only one of Washington's slaves who was freed immediately by Washington's will. Because he served by Washington's side throughout the American Revolutionary War and was sometimes depicted next to Washington in paintings, Lee was one of the most publicized African-Americans of his time.
The man holding the horse in John Trumbull's George Washington, painted in London in 1780, possibly represents Lee and was painted from memory five years after Trumbull served on Washington's staff.
