Book excerpt: Marianne Moore (1887-1972) has been heralded as America's greatest poet of the modernist movement. Her volume Collected Poems won the National Book Award and the Pulitzer Prize in 1952 and the Bollingen Prize in 1953. Born in St. Louis, Missouri, Moore eventually found her way to New York with her mother whom she continued to live with until her mother passed, a familial devotion so intense that William Carlos Williams complained that it was 'pathological' and prevented her from marrying any 'literary guys'. Moore never married. Linda Leavall is the first biographer to be granted access and freedom to quote from Moore's archives. More than just a standard biography, Leavall re-examines Moore's body of work to complement and enlighten the biography. Through Moore's poems and letters from T. S. Eliot, William Carlos Williams, and many others, Leavall has written what is sure to be the definitive biography of Moore.
