Élisabeth Barbier was the pseudonym of Renée Guérin. She grew up in Paris, where she was educated, but spent summers in the south of France, where she had been born. In 1935, she married Raymond Barbier, a physician in Avignon. She loved the theater and led an amateur troupe of actors while pursuing a career as a writer. She participated in the founding of the Festival d'Avignon. She became famous with her popular 1947 novel Les Gens de Mogador
(People of Mogador), a multi-generational family saga set near Avignon. She served as a jury member of the Prix Femina in 1958. Her friends included Marguerite Yourcenar, Pierre Boulle, and Isabelle Rivière, other writers from Avignon.
