Françoise d´Aubigné, Marquise de Maintenon (1635-1719)

"Françoise d'Aubigné (27 November 1635 – 15 April 1719), known first as Madame Scarron and subsequently as Madame de Maintenon (French: [madam də mɛ̃t(ə)nɔ̃] (listen)), was a French noblewoman who secretly married King Louis XIV. Although she was never considered queen of France, she was one of the King's closest advisers and the royal children's governess. In 1684, she founded the Maison royale de Saint-Louis, a school for girls from poorer noble families." - (en.wikipedia.org 24.05.2021)
