Charles Jean Dehoy (1872-1940) was a Belgian painter, watercolorist and etcher; associated with a group known as the "Brabant Fauvists [fr]".

Over the following years, to help support his five siblings, he held numerous odd jobs, including errand boy, cobbler, saddler, and house painter.

As a result, he joined an artists' group named Labeur [fr], which had been founded by Schirren's friend, Auguste Oleffe, in 1898.

In 1912 Georges Giroux [fr], the owner of a fashion boutique, opened an art gallery in Brussels.

By then, he was beginning to influence younger artists himself; notably Médard Verburgh [fr] and Jean Brusselmans.

That same year, he met Paul Fierens [fr], an art critic who would be one of his major supporters, and his works were exhibited at the Salon d'Automne.

After the war, he joined the Cercle des XV [fr], a society dedicated to reviving art.
