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".
Françoise Marie de Bourbon
Her mother-in-law wrote the following in her memoirs:"all the ladies in waiting have made her believe that she did my son honour in marrying him; and she is so vain of her own birth and that of her brothers and sisters that she will not hear a word said against them; she will not see any difference between legitimate and illegitimate children."
Not long after their marriage, Philippe openly ridiculed his wife's bad temper, nicknaming her "Madame Lucifer". Her mother-in-law said that during the early years of the Chartres marriage, Françoise was as "drunk as drunk" three to four times a week.
The union, despite open discord, produced eight children, several of whom later married into other European royal families during the Regency of her husband for the young king Louis XV of France. Françoise Marie was so annoyed at her children not being recognised as grandchildren of a king that Saint-Simon wrote:"The duchesse d'Orléans had a head filled with fantasies that she could not realise... Not content with the modern rank of Granddaughter of France, which she enjoyed through her husband, she could not bear the idea that her children were only Princes of the Blood and dreamed up a rank for them that was betwixt and between...Great-Grandchildren of France."
