Dubois exhibited on a regular basis especially at the Salon de la Société des Artistes Français.
It seems that Dubois became an honorary curator of the Museum of Cosne-sur–Loire later in life and died at Villejuif in 1952, poor and forgotten[1] He was well known for his bust of Marianne, the original of which can be found in the museum at Cosne-sur-Loire in the Nièvre region which also holds many casts of his works.
The Marianne bust was replicated many times and examples can be seen throughout France, normally in pride of place in the "mairie".
Dubois worked on many monument aux morts (war memorials), such as those at Avion, Saint-Amand-en-Puisaye and Cosne-sur-Loire.
Fernand-Dubois completed the Nièvre monument aux morts and those at Ciez, Perroy and Saint-Vérain.
