Gwen de Bonneval was born in 1973 in Nantes. At the beginning of his career he worked for the press and in children's publishing. In 1998 he joined the Atelier des Vosges and devoted himself to his greatest passion: comics. With scriptwriter Fabien Vehlmann, he created the series "Samedi et Dimanche" (Dargaud; Europe Comics 2019), and both wrote and illustrated the series "Basile Bonjour" for publisher Delcourt. Later, together with some friends (including Matthieu Bonhomme and Stéphane Oiry), he created the Atelier du coin. There he worked on projects like "Monsieur Forme" (Delcourt), "Gilgamesh" (Dargaud), and "Messire Guillaume" (Dupuis), the latter of which was recognized at the Angouleme Comics Festival. In 2013, he published the last volume of the series "Bonneval Pacha" (Dargaud). His most recent work includes the saga "Le Dernier Atlas," together with Fabien Vehlmann and Hervé Tanquerelle (Dupuis; "Last of the Atlases," Europe Comics).
