After several other jobs, Lucien Nortier turned to comics in 1946. At first he succeeded Rémy Bourlès on 'Bob l'Ardent' and he created comics for Jeudi-Magazine and Pic et Nic. Later on, he joined the Vaillant (later Pif Gadget) team. In this magazine, Nortier illustrated a wide range of series, like ' Le Cormoran', 'Sam Billie Bill', ' Lynx Blanc', 'Robin des Bois', 'Le Grèlé 7-13' and 'Fanfan la Tulipe', often in cooperation with fellow artist Christian Gaty. While working for Vaillant/Pif from the 1950s to the 1970s, Nortier collaborated on several other magazines, like Noir et Blanc, L'Intrépidé ('Réseau Secret'), Mireille and Pilote ('Bison Noir').
In 1964 he started 'Thierry la Fronde' in Le Journal de Mickey, inspired by the television series. Other series he made for this magazine are 'La Flèche Viking', 'Mademoiselle d'Artagnan' and 'Allo Toubib'.
In the late 1970s he was present in Tintin ('Rintintin', 'Le Trio Black'), followed by an appearance in Jeunes Années Magazine. In the 1980s Nortier cooperated on several educational publications by Chancerel and Hachette, and on the magazines Les Petits Juniors and Télé 7 Jours. With his classical and dynamic graphics, Lucien Nortier is considered one of the best realistic post-war artists.
