Who was Marie d’Agoult?

Marie de Flavigny, countess d’Agoult (1805–1876), was a prominent French writer and a significant figure in 19th-century Parisian society.1

Though married to Col. Charles d’Agoult, she famously left her husband and family in 1835 to begin a relationship with the composer Franz Liszt. The couple lived together for several years, primarily in Switzerland and Italy, and had three children, including Cosima. Liszt commemorated their time together in his piano collection Années de pèlerinage (Years of Pilgrimage).12

Following their permanent separation in 1844, she returned to Paris and established herself as a writer and a salon leader. She authored several works, including the autobiographical novel Nélida and various political and historical texts. As a close friend of the novelist George Sand, she was deeply involved in the intellectual and political circles that influenced the Revolution of 1848. Her memoirs remain a valuable historical resource for understanding the social and artistic life of her era.1
