Léontine Zanta received her bachelor's degree in 1893. In 1914, she became the first woman in France to earn a doctoral degree in philosophy. She was an intellectual celebrity of her day, a journalist for L'Echo de Paris, Le Figaro, and Le Petit Journal, and active in the French feminist movement of the 1920s. She was famed for her beauty and generosity as well as for her intelligence. Her academic speciality was the 16th-century revival of the Greek philosophy of Stoicism. Léontine met Pierre Teilhard de Chardin through a cousin, and they became close friends and devoted correspondents; their letters have been published. She was a member of the jury for the Prix Femina for 20 years. Her biography, Léontine Zanta: Vertueuse aventuriere du feminisme (1997) was written by Henri Maleprade.
