After his studies in fine arts, Christian Catignol learned the finer points of the comic profession from Raymond Poïvet. In 1947, he started using the pseudonym Gaty and started off his solo career with 'Jack Tremble', as well as some comics biographies in Vaillant. From 1949, he was also active in the daily press. He adapted 'L'Atlantide' in France-Soir, 'Le Forgeron de la Cour Dieu' in Libération, and 'L'Étoile du Soir' and some vertical comics in La Dépêche du Midi. In addition, the Opera Mundi agency distributed his adaptation of 'Cigale de Chine', and he did various comics adaptation of literary works in the collection Mondial Aventures of the Société Parisienne d'Édition.
