Born in Liège, Pierre Renoir began his career as an inker for Mittéï at the age of 17. By 1975 he created the character 'Nanouche' with scriptwriter Janeiro for Tintin magazine under his pseudonym, Renoy. Lombard collected the comics in four books until 1983.
He eventually left comics and opened a small bistro/galery called La Cane à Buse in Tilff, not far from Liège. He continues to make watercolor and oil paintings. He is the brother-in-law of Derib.
