Born in Toulouse, Martin began with the Laurens Studio and exhibited in the Salon in 1880. During a visit to Italy in 1885, he discovered and adopted a special Pointillist technique which enabled him to portray the intensity of his poetic feelings. These short strokes, detached and parallel, lend a hazy atmosphere to his paintings.
Later he incorporated the Pointillist technique into murals commissioned at the Sorbonne, the Conseil d'Eta, the Paris Hotel de Ville, and the Toulouse Capitol.
