Hughes began the first of a projected four-volume biography of Washington in October 1926. Based on extensive research, "George Washington: The Human Being and the Hero" covered his life up to the age of thirty. Volume two, "George Washington: The Rebel and the Patriot" (1927), examined Washington's life prior to and in the early years of the American Revolution from 1762 to 1777. The third volume, "George Washington: Savior of the States, 1777–1781" (1930) further examined Washington as a military leader during some of the revolutions darkest days. Hailed by historians as a groundbreaking work, it repaired much of the damage done to Hughes' reputation. An intended fourth volume covering George Washington and his role as the first President of the USA was never completed.
