The poems here come from her book Flame and Shadow, 1920
Sara Teasdale was an early 20th century American poet. She was born in St Louis in 1884, but moved to New York City in her early 30’s. Her book of poetry, Love Songs, won a Pulitzer Prize in 1918. It was a special prize because the Pulitzer Prize for Poetry wasn’t established until 1922.
She was active from the first decade of the 20th century to the 1930’s. Other books of poetry include Helen of Troy and Other Poems (1911), Dark of the Moon (1926), and Stars To-Night (1930).
Teasdale’s anti-war poem “There Will Come Soft Rains” (published in 1918) inspired a short story of the same name by science fiction author Ray Bradbury.
After her marriage, she went by her married name, Sara Teasdale Filsinger, so you may see her work under that name.
Teasdale was a lyric poet so some of her work has been set to music.
Teasdale took her own life in 1933.
