Wharton's most famous works include The House of Mirth (1905), a devastating portrait of a beautiful but penniless socialite destroyed by the rigid conventions of New York's elite; Ethan Frome (1911), a stark New England tragedy; The Custom of the Country (1913), a satire of social ambition; and The Age of Innocence (1920), which examines the constraints of 1870s aristocratic society through a doomed love triangle. Her nonfiction debut, The Decoration of Houses (1897), co-authored with Ogden Codman Jr., also proved influential in interior design.
A close friend of Henry James, Wharton lived much of her life in France, where she aided refugees during World War I and received the French Legion of Honour. Her elegant prose and sharp social insight secure her enduring literary reputation.
