She was the youngest child. Because of that, she was spoiled and waited on like a princess. She never had to do normal chores, like make her bed, or do the dishes. She was known to have described herself as "a flower in a toiling world". Because she was so sickly, she was homeschooled until she was nine. She never had communication with her peers. Teasdale grew up around adults. She was forced to amuse heself with stories and things that she made up in her own lonesome world. When Teasdale was ten, she had the first communication with her peers. Her parents sent her to Miss Ellen Dean Lockwood's school for boys and girls. When she was fourteen, she went to Mary Institute. She didn't graduate there, but switched to Hosmer Hall when she was fifteen. There, she began to put the thoughts and dreams that amused her as a girl onto paper. Thus, she wrote her first poem. Teasdale's first published poem was "Reedy's Mirror", and it was published in a local newspaper. Her first collection, "Sonnets to Duse and Other Poems", was published in 1907. In 1911, her second collection, "Sonnets to Duse and Other Poems" was published. She published many other collections including "Rivers to the Sea", "Love Songs", "Flame and Shadow", "Dark of the Moon", "Stars To-night", and finally, "Strange Victory". Teasdale married her sweetheart Ernst Filsinger in 1914. They had a happy marriage, but it was too good to last. They divorced in 1929, and lived the rest of her life only for her poetry. Sara was always frail and sickly, but in 1933, Teasdale caught chronic pneumonia and it weakened her not only in body but also in mind and spirit. No longer able to see the beauty in simple things, Teasdale committed suicide at age 48 in New York, NY on January 29, 1933. Her final book of poetry was published that year. Teasdale's works continue to be admired by poets everywhere. her works show us what a lovely person she was, and how much she appreciated the beautiful things about life. Her love for beautiful things appeared in her poetry. She was a very talented poet, and we are glad she shared her talent with us.
