E. M. Delafield (1890–1943), born Edmée Elizabeth Monica de la Pasture, was a British author best known for her sharp wit and keen observations of middle-class life. Her most famous work, *The Diary of a Provincial Lady*, established her as a master of comic fiction, but Delafield's writing spanned a wide range of genres, including novels, essays, and plays. Her works often focused on the lives and struggles of women in early 20th-century England, blending humor with subtle social critique.Delafield grew up in a literary family and briefly became a postulant at a convent before pursuing a career in writing. Her experiences during World War I, serving as a volunteer nurse, deeply influenced her later work, especially in her depictions of the challenges faced by women during times of social upheaval. In *The Optimist*, one of her earlier novels, Delafield examines the tension between idealism and reality, themes that would recur throughout her writing.A sharp observer of the domestic and societal roles imposed on women, Delafield brought a satirical yet empathetic voice to the struggles of everyday life. Her ability to combine humor with thoughtful social commentary secured her place as a significant figure in British literature.
