Marianne Moore (1887–1972), born in Kirkwood, Missouri, USA, was a major American modernist poet and editor of The Dial from 1925–29. Among other modernist poets with whom Moore sustained significant connections were T. S. Eliot, H. D., Ezra Pound, and Wallace Stevens. Moore attended Bryn Mawr College for women in Pennsylvania between 1905 and 1909; thereafter she moved to New York with her mother, Mary Warner Moore, where they would reside together until Mary Warner Moore died in 1947 and where Moore would remain until the end of her life. Moore’s major publications include Selected Poems (1935), with an introduction by T. S. Eliot; Collected Poems (1951), for which Moore received the Pulitzer Prize and the National Book Award; and Complete Poems (1967), which was re-edited and reissued in 1981. Her extensive body of criticism is available in The Complete Prose of Marianne Moore. Moore’s archive, including her library and personal effects, is housed at the Rosenbach Museum and Library in Philadelphia; additional papers are located at the Harry Ransom Center at the University of Texas at Austin and the Beinecke Library at Yale University. Linda Leavell’s biography of Moore, Holding on Upside Down, appeared in 2013.
