Aglaé Cadet

Aglaé-Geneviève-Eurélie Cadet de Gassicourt, known as Aglaé Cadet (c. 1738 – 1801) was a French enamelist and painter of miniatures.

Born in Paris, Cadet was the daughter of lawyer Jean-Pierre Joly, and was supposedly a distant relation of the marquis de Marigny; her family claimed a portion of his estate at one time. In 1761 she became the second wife of Claude-Antoine Cadet de Gassicourt. Their daughter Marie-Aglaé, later married to printseller Julien-François Fatou, became a miniaturist like her mother. A second daughter, Rosalie-Louise, having divorced her first husband, became the wife of the marquis de Montalembert, while a third, Henriette-Thérèse, married Jean-Baptiste Weyler, who is believed to have been her mother's instructor.
