After having several jobs, Jacques Lob started making humorous illustrations in French magazines like Le Hérisson, Télé-Magazine, Fiction and Bizarre. In 1960 and 1961, he was present in Hara-Kiri. After Jean-Michel Charlier advised Lob to focus on writing scenarios and abandon drawing, he wrote several stories for artists like Pierre Guilmard, Mézières and Jo-El Azara, that were published in Pilote and Record. In 1964, he collaborated with Georges Pichard for the first time, creating the 'Ténébrax' series in Chouchou. After a brief stint in Tintin working with Azara, Lob teamed up with Morchoisne to create 'Kouakou' in the African magazine of the same name.
