Jérôme Mesnager was born on January 29, 1961 in Colmar.

He entered the Boulle school in 1974 where he received training as a cabinetmaker, a subject he would later teach at the same school. In 1979, he took comic strip classes with Yves Got and Georges Pichard, professors at the School of Applied Arts.

In 1982, Jérôme Mesnager co-founded Zig-Zag, a group of young artists who invested in a "zig-zag through the urban jungle" and revitalized abandoned places with lots of graffiti. His body covered in white paint, Jérôme wandered through these spaces and, on January 16, 1983, projected his first White Man, "a symbol of light, strength and peace," onto the wall of the Petite Ceinture.

From now on, the white body is displayed throughout Paris, exploring factories and disused stations without forgetting cellars and catacombs... before setting off to conquer the entire world: Italy, Senegal, Gambia, Mauritania, the United States, Egypt, Japan, China.
