Margaret Bayard Smith (1778-1844) was a friend of Thomas Jefferson and chronicler of early life in Washington, D.C. She met Jefferson through her husband, Samuel Harrison Smith, a Republican newspaperman and founder of the National Intelligencer.
Her recollections of Washington society life in the early nineteenth century constitute one of the major sources of information on Jefferson's social life as President. After Jefferson's retirement from political life, Smith visited him at Monticello. Her account of this visit is another fruitful source of information on Thomas Jefferson's daily life and family.
