Gérard Lauzier studied architecture and philosophy before he started his artistic education at the ateliers of Perret and Lagneaux. After producing some work for the press, he went to Brazil for a couple of years, where he did advertising work, as well as caricatures for Le Journal de Bahia (1958-59). Back in France, he returned to humorous illustrations. He contributed to several magazines until 1973, including Lui, France-Soir, Paris-Match and Paris-Presse.
In 1974, he entered the comics field, producing the albums 'Lili Fatale' and 'Un Certain Malaise'. In that same year, he began an association with Pilote magazine, that lasted throughout the 1970s and 1980s, and with Lui for which he created 'Zizi Panpan'. A year later he created 'Les Chroniques de l'île Grande', that was directly inspired by his trip to Brazil.
In Pilote, Lauzier made social satires with sharp, witty dialogues in his 'Tranches de Vie' (1974-1978) feature and subsequent projects 'La Course du Rat' (1978), 'La Tête dans le Sac' (1980), 'Les Cadres' (1981) and 'Souvenirs d'un Jeune Homme' (1982). He also wrote the hilarious western parody 'Al Crane' for Alexis in 1976. By the end of the 1980s, he dropped his comic activities to concentrate on theatre and cinema scriptwriting. He cooperated on several theatrical productions, including an adaptation of his comic 'Tranches de Vie'.
