Jeanne Antoinette Poisson, Marquise de Pompadour, also known as Madame de Pompadour (29 December 1721 – 15 April 1764, ), was a member of the French court and was the official chief mistress of Louis XV from 1745 to her death. She took charge of the king’s schedule and was a valued aide and advisor, despite her frail health and many political enemies. She secured titles of nobility for herself and her relatives, and built a network of clients and supporters. She was particularly careful not to alienate the Queen, Marie Leszczynska. She was a major patron of architecture and decorative arts such as porcelain. She was a patron of the philosophes of the Enlightenment, including Voltaire. Hostile critics at the time generally tarred her as a malevolent political influence, but historians are more favourable, emphasizing her successes as a patron of the arts and a champion of French pride.
