Marius Barret (1865-1929) trained as an artist at the École des Beaux-Arts in his home town of Marseille. He studied under Dominique Magaud, Raphaël Collin and Jean-Baptiste Olive. He painted portraits, history paintings, genrepaintings and the landscape around his native Marseille. Later in his career he became a teacher at the École des Beaux-Arts, his alma mater. He exhibited at the Paris Salon des Artistes Francais between 1886 and 1928, receiving a silver medal in 1928 and an honourable mention in 1928.
Work by Barret can be found in the collection of the Musée des Beaux-Arts, and Musée Cantini, both in Marseille.
