Philippe Dupuy

Philippe Dupuy is a French cartoonist and scriptwriter, born on 15 December 1960 in Sainte-Adresse (Seine-Maritime).

Philippe Dupuy and Charles Berberian are most famous for their series of Franco-Belgian comics albums featuring the character Monsieur Jean. Their collaboration is notable as they share every aspect of creating their stories, from plot through layouts, pencils and inks, to the extent that it is impossible to detect who is responsible for what. But in 2003, they decided to again work on their own, and have since published solo material like Hanté by Dupuy in 2005.
