In 1884, Sara Trevor Teasdale was born in St. Louis, Missouri, into an old, established, and devout family. She was home-schooled until she was nine and traveled frequently to Chicago, where she became part of the circle surrounding Poetry magazine and Harriet Monroe. Teasdale published Sonnets to Duse, and Other Poems, her first volume of verse, in 1907. Her second collection, Helen of Troy, and Other Poems, followed in 1911, and her third, Rivers to the Sea, in 1915.
In 1914 Teasdale married Ernst Filsinger; she had previously rejected a number of other suitors, including Vachel Lindsay. She moved with her new husband to New York City in 1916. In 1918, she won the Columbia University Poetry Society Prize (which became the Pulitzer Prize for poetry) and the Poetry Society of America Prize for Love Songs, which had appeared in 1917. She published three more volumes of poetry during her lifetime: Flame and Shadow (1920), Dark of the Moon (1926), and Stars To-night (1930). Teasdale's work had always been characterized by its simplicity and clarity, her use of classical forms, and her passionate and romantic subject matter. These later books trace her growing finesse and poetic subtlety. She divorced in 1929 and lived the rest of her life as a semi-invalid. Weakened after a difficult bout with pneumonia, Teasdale committed suicide in 1933 with an overdose of barbiturates. Her final collection, Strange Victory appeared posthumously that same year.
