Petitot initially studied under Claude François Devosge at the École des Beaux-Arts in Dijon. In 1788 he won the first major sculpture prize founded by the States of Burgundy, which allowed him to travel and stay in Rome. His award-winning statue was on display in the Musée des Beaux-Arts de Dijon. After he returned to France, he was imprisoned as a suspect and it was 27 July 1794. He regularly exhibited at the Salon (Paris) until 1819. He worked with Pierre Cartellier and Joseph Espercieux. The Museum of Dijon has an oil on canvas portrait he executed of the artist Pierre-Paul Prud'hon, and The Louvre also contains some of his works.
