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".
Marie Thérèse Louise of Savoy, Princesse de Lamballe
The "Gazette de France" mentions Madame de Lamballe's presence in the chapel at high mass on Holy Thursday, at which the King was present, accompanied by the Royal Family and the Dukes of Bourbon and Penthièvre. In May 1771, she went to Fontainebleau, and was there presented by the king to her cousin, the future Countess of Provence, attending the supper after. In November 1773, another one of her cousins married the third prince, the Count of Artois, and she was present at the birth of the future Louis-Philippe of France in Paris in October 1773. After her cousins had married Marie-Antoinette's brothers-in-law, the royal princes, Marie Thérèse de Lamballe came to be treated by Marie-Antoinette as a relation, and during these first years, the counts and countesses of Provence and Artois formed a circle of friends with Marie-Antoinette and the princesse de Lamballe and spent a lot of their time together, the princesse de Lamballe being described as almost constantly by Marie-Antoinette's side. The empress Maria Theresa somewhat disliked the attachment, because she disliked favorites and intimate friends of royalty in general, though the princesse de Lamballe was because of her rank regarded as an acceptable choice, if such an intimate friend was needed.
