Anne Douglas Sedgwick was born in Englewood, New Jersey, but moved at age nine with her family to England, where she lived for the rest of her life. In 1898, her father arranged the publication of The Dull Miss Archinard, a novel she had written for amusement, and it launched her writing career. She married Basil de Sélincourt, a journalist and essayist, in 1908. During World War I, she and her husband worked as volunteers in hospitals and orphanages in France. Her writing often explored the contrast in values between Americans and Europeans and was highly popular in its day. Four of her books were on the New York Times bestseller lists for 1912, 1924, 1927, and 1929. Her novel Tante (1912), her first major success, was adapted into a 1919 film called The Impossible Woman, and The Little French Girl (1924) was made into a 1925 film of the same name. She also wrote some nonfiction, including A Childhood in Brittany Eighty Years Ago (1919). In 1931, she was elected to the National Institute of Arts and Letters in the USA. After her death, her husband published Anne Douglas Sedgwick: A Portrait in Letters.
