The French painter Jacques Grange Leautey was one of the main contributors to vertical comic strips to newspapers like France Soir. Born in Paris, Grange studied at the School of Applied Arts and worked with the couturier Paul Poiret for a while. He eventually turned to humorous illustration, and contributed to Ecoutez-Moi, Vendémiriaire and Marianne during the 1930s. In 1938, he participated in the founding of the Salon des Imagiers. Grange focused on painting during the War, and upon the liberation, resumed his work for the press.
He became a productive artist of episodes of 'Le Crime ne Paie Pas' and 'Les Amours Célèbres' strips, that appeared in the daily France-Soir from 1950 to 1970. These "vertical" comics, written and documented by Paul Gordeaux and later Robert Mallat, dealt famous historic police enigmas and love stories. After a while, Grange also drew strips in this genre for Jours de France. For 24 Heures, he made a comics version of Alain Decaux' 'La Castiglione' and Pierre Benoît's 'Alberte'. He also continued to paint, and exhibited his work until his death in the early 1980s.
