When the Pulitzer Prize for Poetry was awarded in 1918, Sara Teasdale stood among its recipients — a formal recognition that arrived just a year after her 1917 poetry collection Love Songs appeared in print. That sequence of events, a collection followed swiftly by a prize, sits at the center of her documented career.

Born on August 8, 1884, in St. Louis, Teasdale received her education at the Mary Institute and St. Louis Country Day School. The city shaped her early years, though her life would carry her well beyond Missouri. In 1914 she married, and records of her life note that she took the name Filsinger alongside her literary identity. Her poetry, written in English, continued through these years, and Love Songs, published in 1917, appeared the year before the Pulitzer committee made its recognition official.

Teasdale worked as a poet and writer, and her output placed her within American verse of the early twentieth century. The Pulitzer Prize for Poetry she received in 1918 gave her work an institutional standing, and the Library of Congress's authorized catalog entry — "Teasdale, Sara, 1884–1933" — preserves the span of that career in its most compressed form. Her name, bracketed by those two dates, moves from a St. Louis birth through marriage, through a prize-winning moment, and toward the city where her life ended.

She died in New York City on January 29, 1933, at the age of forty-eight. The Library of Congress record that frames her life between 1884 and 1933 remains one of the most concrete markers of her place among American poets writing in English during the first decades of the twentieth century. The Pulitzer Prize for Poetry, received in 1918, stands as the most formally documented acknowledgment of her work.
