Baron Antoine-Jean Gros (16 March 1771 – 25 June 1835), also known as Jean-Antoine Gros, was both a French History and neoclassical painter.
Born in Paris, Gros began to learn to draw at the age of six from his father, who was a miniature painter, and showed himself as a gifted artist. Towards the close of 1785 Gros, by his own choice, entered the studio of Jacques-Louis David, which he frequented assiduously, continuing at the same time to follow the classes of the Collège Mazarin.
