Jérôme Mesnager was born in Colmar, in the Alsace region of northeastern France. He attended École Boulle – a school of fine arts&crafts and applied arts, named after André-Charles Boulle, a well-known cabinetmaker from the XVII century. In 1974, he got his degree in cabinetmaking course. For a while, he was teaching this craft at Boulle. However, the city and its streets were calling him to adorn them with some excitingly ephemeral art. In 1979, Mesnager made a smooth transition towards a bit more urban art by attending Yves Got’s and Georges Pichard’s comics’ course at The Duperré School of Applied Arts. Pichard was known for many BD Franco-Belgian comics magazine covers and Got was a creator of Didou, a small animated rabbit hero. In 1982, gravitating fast to his current artistic expression, Mesnager co-founded a Zig-Zag in 1982. This group gathered young artists, eager to occupy streets and abandoned factories with their graffiti and performances, so their voice could be heard, or better said: seen.
