François Craenhals was born in Evere in 1926. He was a fan of American comics by Alex Raymond and Hal Foster, and created his first comic Karan in the vein of Tarzan at the end of the 1940s. For the weekly magazine Le Soir Illustré, he made at the same time a medieval comic about a knight.
When he presented these comics to Tintin magazine, he was accepted as art director and gradually started making short comics for the magazine. His first main series debuted in 1953: Pom et Teddy was a series about a boy and a girl and their pet donkey, and the first stories were gentle stories about a circus.
Craenhals soon became one of the main producers of comics for magazines and newspapers, and a number of collaborators joined his studio. He worked for the Averbode magazine Petits Belges, and published for many years Primus et Musette in La Libre Belgique.
