E.M. Delafield (1890–1943)

E.M. Delafield was the pen name of Edmee Elizabeth Monica Dashwood, née de la Pasture, born in Steyning, Sussex, England, the daughter of well-known novelist Elizabeth Bonham and her husband Count Henry Philip Ducarel de la Pasture. Delafield was educated by French governesses and attended several boarding schools, followed by nine months as a postulant nun in a convent in Belgium. She worked with the Voluntary Aid Detachment (VAD) during World War I, and these experiences formed the basis of her first novel, Zella Sees Herself, published in 1917. She continued to publish one or two novels every year until her death. She is best known for the bestselling series The Diary of a Provincial Lady and its sequels. She also was an important contributor of book reviews, sketches, and short stories to Time and Tide magazine. In 1919, she married Colonel Arthur Paul Dashwood, an engineer, and they spent two years living in the Malay States before returning to live in an old house in Kentisbeare, Devonshire. The couple had two children, and Delafield served as president of the Kentisbeare Women's Institute for the the rest of her life. Her daughter Rosamund Dashwood published Provincial Daughter, a continuation of Delafield's popular series of books, in 1961.
