Louise de Broglie, Countess d'Haussonville was a French essayist and biographer, and a member of the House of Broglie, a distinguished French family. A granddaughter of the novelist Germaine de Staël, she was considered independent, liberal, and outspoken. Her 1845 portrait by Jean-Auguste-Dominique Ingres, which took three years to complete, has been exhibited in the Frick Collection in New York City since the 1930s.
