Louise Marie Madeleine Fontaine
Louise-Marie-Madeleine Guillaume de Fontaine (after marriage known as Madame Dupin; 28 October 1706 – 20 November 1799) was a French "saloniste".
Madame de La Fayette
In 1655, de la Vergne married François Motier, comte de La Fayette, a widowed nobleman some eighteen years her senior, with whom she would have two sons. She accompanied him to country estates in Auvergne and Bourbonnais although she made frequent trips back to Paris, where she began to mix with court society and formed her own successful salon. Her sister-in-law was Louise de La Fayette (1618–1665), favourite of Louis XIII of France. Some of her acquaintances included Henrietta of England, future Duchess of Orleans, who asked La Fayette to write her biography; Antoine Arnauld; and the leading French writers Segrais and Huet. Earlier on, during the Fronde, La Fayette had also befriended the Cardinal de Retz with whom her stepfather was associated.
