"Anne d'Arpajon, comtesse de Noailles (Anne Claude Louise d'Arpajon; 4 March 1729 – 27 June 1794) was a French noblewoman and court official. She served as the dame d'honneur of two Queens of France, Marie Leszczyńska and Marie Antoinette. She was called "Madame Etiquette" by Marie Antoinette for her insistence that no minutia of court etiquette ever be altered or disregarded." - (Wikipedia (en) 22.05.2021)
