English: Marie-Louise O'Murphy (21 October, 1737 – 11 December, 1814) was a courtesan, one of the several mistresses of King Louis XV of France. In 1752, at barely fifteen years of age, she posed nude for two memorable and provocative portraits (L'Odalisque Brune) by artist François Boucher. Her beauty caught the eye of a royal valet who introduced her to the king, Louis XV. He took her as one of his mistresses, and she quickly became a favourite, giving birth to the king's illegitimate daughter, Agathe Louise de Saint-Antoine (1754 – 1774).
