Louise Florence Pétronille Tardieu d'Esclavelles d'Épinay (11 March 1726 – 17 April 1783), better known as Mme d'Épinay,[1][2] was a French writer, a saloniste and woman of fashion, known on account of her liaisons with Friedrich Melchior, Baron von Grimm, and Jean-Jacques Rousseau, who gives unflattering reports of her in his Confessions, as well as her acquaintanceship with Denis Diderot, Jean le Rond d'Alembert, Baron d'Holbach and other French men of letters during the Enlightenment.
She settled in the Château of La Chevrette in the valley of Montmorency, a few miles north of Paris, and there received a number of distinguished visitors.
Conceiving a strong attachment for Jean-Jacques Rousseau, she furnished for him in 1756 in the valley of Montmorency a cottage which she named the Hermitage, and in this retreat he found for a time the quiet and natural rural pleasures he praised so highly.
Many of Madame d'Épinay's letters are contained in the Correspondance de l'abbé Galiani (1818), which provided material for Francis Steegmuller's joint biography,[9] and have since appeared in a definitive redaction.
In January 1783, three months before her death, she was awarded the Prix Monyon, recently established by the Académie to honour the author of the "book published in the current year that might be of most benefit to society"; it was her Conversations d'Émilie (1774).
