Jean Dubois (Belgian, 1923 - 1990) was a painter and engraver. As an abstract painter, he was one of the defenders of constructed art in Wallonia. He practised both oil painting and relief painting, combining wood and painted canvas. 

After studying at the Industrial School of Jumet, he completed his training at the studio of M. Stievenart and at the Academy of Nivelles (H. Quittelier). 

However, he considered himself a self-taught painter. He was initially influenced by R. Heintz.  Thanks to skilled craftsmanship and meticulous finishing, as well as an innate sense of harmonious proportions, Jean Dubois managed to make his work undergo a fruitful dialogue between static rigour and dynamic tension. A comment by Claude Lorent: "The whole responds to the addition of complementary interventions or contradictions, thus finding an intense and intimate life". 

Dubois is a founding member of the group Art Concret en Hainaut and was also a member of the group Artistes du Hainaut. 

He won the 'Schilderprijs van Knokke' ('Knokke Painting Prize') in 1977 and a competition to integrate artworks for a sports hall in 1980. He exhibited repeatedly in Charleroi, notably at the Palais des Beaux-Arts in 1972. 

Initially influenced by R. Heintz, Matisse and Léger, he turned to abstraction in the mid-1960s, resulting in a constructed art influenced by Dewasne, Herbin and the American minimalists. 

Jean Dubois' work is part of the geometric, 'constructed abstraction movement'. The artist, a lover of pure flat colours, used both surface and light reliefs. His painted surfaces, which are wide open, are combined with a formal and geometric language in which verticality imposes itself. Pure colours are used with austerity. He evolves towards a use of relief that exploits the vertical flow of colour and denounces the optical effects of which the surface can be the object. A lover of pure flat colours divided into vertical strips that often animate thin oblique lines of contrasting tone, he also escapes the traditional format of the easel by breaking up the surfaces.
