Montezin as a young man entered the studio of decorative arts and there he learnt quickly to draw decorative murals. His teacher however encouraged the young Montezin to study the theories of Impressionism and he was later to abandon his work as a collage artist and concentrate on painting landscapes applying the ideals of the pleinairists.
The strongest influence on Montezin was Claude Monet, and after the First World War he spent a year in the countryside around Dreux and Moret following in the footsteps of Alfred Sisley. He remained loyal to the Impressionistic principles throughout his career, never following the emerging movements of Cubism, Surrealism or Abstract Art. Like Cézanne, he also died whilst painting in the open air.
