Noël Gloesner started his career shortly after World War II at Fleurus publishers. His first comic, 'Les Mille et Une Aventures de Chiffonnette', appeared in Fripounet et Marisette. In February 1947, he launched the 'Les Indégonflables de Chantovent' series along with Rose Dardennes in that same magazine. He drew the series about fourteen years, and launched a new version in 1975. Also for Fripounet, he produced 'Le Roman de Renard' and 'Les Lionceaux'.
Gloesner cooperated on the 'Yann le Vaillant' series in Coeurs Vaillants from 1948 to 1956. The series was signed Jacques Conoan, a collective pseudonym for Jacques Romont (Jacques), Colette (Co), Noël Gloesner (No) and André (An).
