Marcel Moniquet was part of the first generation of Belgian comic artists. Born in Liège, he attended the Academy of Fine Arts in Saint-Gilles. After World War I, he started working as an artist and illustrator at his family's advertising firm, before he began concentrating on comics. His first comic, 'Toto Snuts, Vedette de Cinéma', was published in Sourire du Monde in 1939. He joined the Guy Depière studios in 1941, where he cooperated on several magazines, like Aventures Illustrées-Bimbo ('Roberjac', 'Tommy Tuller', 'Robin Moderne', 'Le Chevalier Fantôme', 'Master'), Jeep ('Blondine', 'Zim-Boum') and Blondine ('Roland le Justicier', 'La Fée Douceur).
In 1948, he created 'Claudine au Pays des Contes' in Annette. A year later, he created several illustrated biographies for L'Explorateur and he started a collaboration with Heroïc Albums. For Heroïc, he took on 'Tommy Tuller again, and created new series like 'Jean des Flandres' and 'Aviorix'. He worked for the magazine until 1956, when he left the comics field. In 1969 and 1970, he had a brief reappearance with some new episodes of 'Aviorix' in the second run of Heroïc-Albums.
