Jeanne Sophie de Vignerot du Plessis
Born as the daughter of duke Louis François Armand de Vignerot du Plessis and Élisabeth Sophie de Lorraine, she was raised with her paternal aunt in a Benedictine convent and married in 1755 to Don Casimir Pignatelli, Count of Egmont.
She hosted a salon which gathered "the literary celebrities of the days" including Voltaire and Rousseau and was a center to the opposition of Madame du Barry. Through her close friendship with the Swedish ambassador to France, U. Scheffer, she came to know the future Gustav III of Sweden during his visit to Paris in 1771 and continued a correspondence with him during his reign. She advised him to "repress the strife of the raging parties", advocated a "monarchy restrained by laws" and greeted his coup of 1772 with joy, especially its unbloodied character. She called Gustav III "The hero of my heart", and it is considered likely that she had influence "upon the enlightened, human, in many ways liberated direction of the early reign of Gustav III".
