Louis-Michel Carpentier was born in Uccle. After his education at the Academy of Fine Arts in Brussels, he initially focused on animation, and found employment with the Belvision studios of Éditions Lombard in 1967. He was an inbetweener on the films 'Astérix et Cléopâtre' and 'Tintin et le Temple du Soleil', and chief animator for 'Tintin et le lac aux requins', the 'Lucky Luke' film 'Daisy Town' and 'La flûte à six schtroumpfs'. By 1975, Carpentier adapted a few novels by the Countess of Ségur to comic stories for the women's magazine Femmes d'aujourd'hui. Casterman collected them in ten books between 1975 and 1984.
Carpentier has worked extensively with scenario writer Raoul Cauvin since the 1980s. Their first collaboration was the post-apocalyptic series 'Les Toyottes', of which the first story was published in Pistil, and of which Casterman and Lombard published six books until 1989. Carpentier also made game pages with the characters for the magazine Jouez avec Quick et Flupke. Carpentier and Cauvin then made a short-lived toyline tie-in comic called 'De Biepjes', and began an association with the educational publisher Artis-Historia and its magazine Artiscope in 1985.
Their best-known collaboration is however the series about the pub owner Poje, initially called 'L'Année de la Bière' and published by Archers in 1986 and 1987.
