Jean-Baptist Defernex (1729–1783) was a French artist best known for his portrait busts, most often of women.
Little is known of his early training, but he started as a modeler at the Sèvres factory. He was sculptor to the Duc d'Orléans and worked on gilded lead statue groups of children at the Palais-Royal. He was not a member of the Royal Academy, but rather that of St. Luke. He had a school for sculpture and drawing; Louis Jean-Jacques Durameau studied there.
Defernex received no official commissions, and his art seems to have been regarded as rather unfashionable. His portrait busts have been compared to those of Jean-Baptiste Greuze and described as "honest, unidealized, quite free from gallant flattery": "All the graces and tender amorous atmosphere that floated about Madame Favart," the singer and actress who was the subject of a 1762 work, "seem dispelled by his convincingly truthful bust of her."[1]
