A British author and Imagist poet, he is best known for his novel Death of a Hero and for his World War I-era poems. He also wrote the controversial 1955 work, Laurence of Arabia: A Biographical Inquiry, and received the James Tait Black Memorial Prize for his 1946 biography, Wellington.
He studied at the University of London, but, as a result of his family's poverty, could not finish his education.
He was wounded during World War I, and he never recovered psychologically from the traumas of combat.
He was married to fellow poet Hilda Doolittle from 1913 until 1938. Later, he wed Netta McCullough.
He had a complicated relationship with his literary contemporary and sometimes friend, T.S. Eliot, whose career he helped and alternately tried to sabotage.
