Gaston Coppens, trained in sculpture at the Ecole Boulle, is very early on oriented towards drawing, particularly lead pencil and pastel, whose graphics bear the characteristics of his training: volume, architecture, relief and harmony.

He set up his workshop in Boulogne-Billancourt and regularly participated in many exhibitions: Salon des Independents, the Society of Mountain Painters, the National Society of Horticulture of France. etc.

Several galleries have devoted personal exhibitions to him and first amongst them the prestigious Bernheim-Jeune gallery (gallery devoted to the Impressionists, Renoir, Cézanne, Matisse …), but also the Royal Gallery and the picturesque Gallery.
