Delporte started at Spirou at the age of 17. Where his first job was to retouch the cleavage in American comics which at the time were considered excessively lewd. He handled other odd jobs, and over time touched upon a great deal of different occupations within the comics industry. In 1955, upon becoming editor-in-chief of Spirou in place of Charles Dupuis, a long-lasting collaboration with Franquin began, which would spawn many creations.
