Although committed to his career as a math teacher, Henri Gillain followed with interest the early developments of comic strips in Belgium, and the artistic evolution of his brother, Jijé, eventually considered by many the second pioneer of Belgian comics after Hergé. In 1952, Henri Gillain submitted another script to Will, another young artist nurtured by his brother, a scenario for Tif et Tondu, Le Trésor d'Alaric, and would on this occasion use the pseudonym Luc Bermar. During this time he was also an anonymous contributor to his Jijé's Blondin & Cirage story Nègre Blanc.
