Michel Constant took courses in comics at the École Supérieure des Arts Saint-Luc in Liège. He then teamed up with scenarist Denis Lapière with whom he created the series about car mechanic 'Mauro Caldi' for Éditions du Miroir. The series was later continued at Alpen publishers, and eventually revived after twenty years at Paquet in 2014. In addition, Constant and Lapière created two short stories for Tintin Reporter. From 1995, Constant drew 'Bitume', a collection of independent stories written by Michel Vandam.
