Louise Marie Madeleine Fontaine
Jean-Jacques Rousseau subsequently sent an inflamed letter to Madame Dupin, who returns him expressing her concern. This doesn't stop the writer for much and only the intervention of Louise's stepson put an end to his attentions. But Madame Dupin was hardly spiteful and some months after these incidents, takes Rousseau in her service and put him in charge of the education of her son Jacques-Armand for eight days pending for a new tutor. Subsequently, the Dupins taken Jean-Jacques Rousseau as secretary after their return from Venice in 1745, when he is not yet a writer and for a modest salary. His job was to take notes and research for the book projected by Madame Dupin, namely "the defense of women in the 18th century are discussed in minor ... until they died". Madame Dupin stood Rousseau almost to a subordinate or, in the words of Grimm and Marmontel, she gives him leave the day it receives academicians. Jean-Jacques Rousseau feels bitterness after leaving his job as a secretary in 1751, but will always keep good relations with the Dupin family. Madame Dupin provides financial support to his wife, Marie-Thérèse Levasseur, who gave birth to five children abandoned by Rousseau to the Foundling Hospital. As for Louis Claude Dupin, his bound with Rousseau came for their common passion for music. The stepson of Madame Dupin was interested in physics, chemistry and natural history, hoping to integrate the Academy of Sciences and the philosopher did write an unfinished book, popular science to "Institutions of Chemistry".
Marguerite of Lorraine
By right of her marriage, Marguerite became known as "Madame" at court. After the death of his mother in 1642, Gaston was bequeathed the Luxembourg Palace, which became the couple's Parisian residence under the name "Palais d'Orléans" once they were restored to royal favour. They also sojourned at the Château de Blois, in the Loire Valley, where their first child was born in 1645. Marguerite, however, did not play any significant role at the French court, although she received a warm welcome after the death of Louis XIII, she suffered from agoraphobia and seldom visited the court where her duties were undertaken by her step-daughter, Mademoiselle, with whom she did not get along.
Marguerite's husband, who had played a major part in the Fronde against his nephew the young king Louis XIV (as had her stepdaughter Anne Marie Louise d'Orléans, "La Grande Mademoiselle"), was exiled to his castle at Blois where he died in 1660. Some time after her husband's death, Louis XIV gave the dukedom of Orléans to his brother (and Gaston's nephew), Philippe of France, Duke of Orléans, who became the new "Monsieur". As "Dowager Duchess of Orléans", Marguerite continued to reside in the "Palais d'Orléans" where she died on 13 April 1672. She was buried at the Basilica of Saint Denis.
