Christian Léger was born in Brive-la-Gaillarde. His father was in the army, and the Léger family has lived in Germany, Morocco and eventually Clermont-Ferrand over the years. At the age of 21, Christian settled in Lyon to study at the École Emile Cohl, where he graduated four years later. Finding it difficult to get art assignments, he went to work in the security field. For four years, he worked on his own comics and children's books projects in his spare time. Finally, in 2004, the publishing house Poisson Soluble published his book 'Cours', which he made together with his wife. In 2002, he got in touch with Thierry Lamy, with whom he created the comics series 'Labiénus'. This series is published by the publishing house Theloma since 2004.
