Julie d'Aubigny (1670/1673 – 1707), better known as Mademoiselle Maupin or La Maupin, was a 17th-century French opera singer. Little is known for certain about her life; her tumultuous career and flamboyant lifestyle were the subject of gossip, rumor, and colourful stories in her own time, and inspired numerous fictional and semi-fictional portrayals afterwards. Théophile Gautier loosely based the title character, Madeleine de Maupin, of his novel Mademoiselle de Maupin (1835) on her.Illustration credit: unknown; restored by Adam Cuerden
