André René Jolly debuted in the Benjamin periodical in 1930. Under the pseudonym Jérôme Érik, later simplified to Érik, he drew 'Les Aventures de Ratinet' and 'Monsieur Toupe' for the magazine during the 1930s. Afterwards, he founded his own magazine, Oscar Bill, le Roi des Détectives, which contained a comic and an illustrated story. Unfortunately, this magazine lasted only 26 issues. During World War II, Érik worked for Gavroche ('Le Professeur Globule'), Grandes Aventures ('Martin Gale, Détective Amateur', 'Le Chevalier Trancheroc') and Le Téméraire ('Dr Fulminate et Pr Vorax').
