Pierre Le Gros
He was born in Nice, then part of the Duchy of Savoy. Van Loo followed his brother Jean-Baptiste to Turin, and then to Rome in 1712, where he studied under Benedetto Luti and the sculptor Pierre Le Gros. After leaving Italy in 1723, he worked in Paris, studied at the Académie Royale, where he gained first prize for drawing in 1723, and received the first prize for historical painting in 1727—as did his future rival François Boucher. In 1724 he won the Prix de Rome.
