His father, Élie Dubois, was a dentist in
Montbéliard and belonged to a religious community known as the
Plymouth Brethren. He studied at the
Académie Julian, followed by
Jean-Paul Laurens and
Fernand Cormon at the
École Nationale Supérieure des Beaux-Arts, and had his first exhibition at the
Salon in 1910. He styled himself as an
ethnographic painter and took part in many missions to North Africa; notably to the area around the
Hoggar Mountains. He presented the works he created there at the
Paris Colonial Exposition of 1931, the
Brussels International Exposition (1935), the
Exposition Universelle (1937) and the
1939 New York World's Fair. In 1933, he married
Henriette Damart, a
pastellist who had worked in Tunisia, and would work with him throughout North Africa. He was the recipient of numerous awards; including the
Abd-el-Tif Prize (1920) and the Grand prix Arts artistique de l'Algérie (1927), His works may be seen at the
National Museum of Fine Arts of Algiers, the
Bardo National Museum (Tunis), the
Musée des Années Trente de
Boulogne-Billancourt, and several others throughout France. In 2019, on the occasion of the 70th anniversary of his death, the city of
Luxeuil-les-Bains paid him tribute. To this end, the Musée de la Tour des Échevins presented a dual exhibition, featuring Dubois and the contemporary Algerian artist,
Hocine Ziani, who has also created paintings at Hoggar. ==Selected paintings==
