Nancy Freeman-Mitford (28 November 1904 – 30 June 1973) was an English novelist, biographer, and journalist. She was the eldest of the Mitford sisters, who were all well known in the social circles at the time. Nancy was regarded as one of the “Bright Young People” on the London social scene in the years between the world wars. Educated privately, she had no training as a writer before publishing her first novel in 1931. Despite her non formal education in terms of writing, she wrote several novels about upper-class life in England and France, and is considered a sharp and often provocative wit. She also has a reputation as a writer of popular historical biographies.
