H.D. (born Hilda Doolittle) (10 September 1886 – 27 September 1961) was an American poet, novelist and memoirist best known for her association with the early 20th century avant-garde Imagist group of poets such as Ezra Pound and Richard Aldington. The Imagist model was based on the idioms, rhythms and clarity of common speech, and freedom to choose subject matter as the writer saw fit. H.D.'s later writing developed on this aesthetic to incorporate a more female-centric version of modernism.
