Charles Willson Peale (April 15, 1741 - February 22, 1827) was an American painter, soldier and naturalist. He is best remembered for his portrait paintings of leading figures of the American Revolution, as well as establishing one of the first museums.
This painting is the earliest authenticated portrait of George Washington and shows him wearing his colonel's uniform of the Virginia Regiment from the French and Indian War. The portrait was painted about 12 years after Washington's service in that war, and several years before he would reenter military service in the American Revolution. Oil on canvas.
This painting hangs in Lee Chapel, and is part of the Washington-Custis-Lee Collection.
