Pierre Culliford (1928 – 1992) was a Belgian cartoonist who worked under the pseudonym Peyo.
Peyo began work, fresh from his coursework at the Académie Royale des Beaux-Arts in Brussels, at the Compagnie Belge d’Animation (CBA), a small Belgian animation studio, where he met a few of his future colleagues and co-celebrities, like André Franquin (best-known for his characters Gaston and Marsupilami) and Morris (Lucky Luke). After working briefly there, Peyo began making comic strips for daily newspapers such as Le Soir, a Belgian newspaper, shortly after World War II.
At the beginning of the 1950s, Peyo was introduced to Spirou, a children’s Franco-Belgian comics magazine published by Dupuis. Peyo wrote and drew a number of characters and storylines, including Pierrot, and Benoît Brisefer (translated into English as Steven Strong). But his favourite was Johan et Pirlouit (translated into English as Johan and Peewit), which was a continuation of the series Johan he had created earlier. He also continued Poussy in Spirou.
