William Hervey Allen (December 8, 1889 – December 28, 1949) was an American author.
He served as a Lieutenant in the 28th (keystone) Division, United States Army during the World War I and fought in the Aisne-Marne offensive July–August 1918. He wrote Toward the Flame (1926), a nonfictional account of his experiences in the war.
His first book, Wampum and Old Gold, was awarded the Yale Younger Poets Prize.
Allen is best known for his work Anthony Adverse. He also planned a series of novels about colonial America called The Disinherited. He completed three works in the series: The Forest and the Fort (1943), Bedford Village (1944), and Toward the Morning (1948). The novels tell the story of Salathiel Albine, a frontiersman kidnapped as a boy by Shawnee Indians in the 1750s. All three works were collected and published as the City in the Dawn. Allen also wrote Israfel (1926), a biography of American writer Edgar Allan Poe.
For a period of time, Allen taught at the Porter Military Academy in Charleston, South Carolina. He also taught English at Charleston High School which at that time, although public, was only for boys. (The girls went to Memminger.) There he met and befriended DuBose Heyward. He later was a professor at Vassar University where he met his wife, Ann "Annette" Andrews. They had three children, Marcia, Mary Ann and Richard.
In the 1940s he co-edited the Rivers of America Series with Carl Carmer. Allen was a good friend of Marjory Stoneman Douglas and instigated her writing The Everglades: River of Grass. Allen was close friends with Robert Frost and Ogden Nash.
