Laurent Pécheux (17 July 1729 – 1821 Turin) was a French-born painter, active in Rome and Northern Italy in a Neoclassical-style.
Born in Lyon, France, Pécheux initially studied at the Jesuit College, but was sent to Paris where he frequented the studio of Charles-Joseph Natoire, Jean-Baptiste Pillement, and Jean-Antoine Morand.
There, at the invitation of Nicolas Guibal, he frequented the studio of Anton Raphael Mengs.
He lived circa 1757 in the neighborhood of Trinità dei Monti, and there set up a teaching studio.
[1][2] He was recruited in 1765 to paint a portrait of Princess Maria Luisa of Bourbon-Parma for the family of her fiancé, the Prince of Asturias, who would later become Charles IV of Spain.
