Georges Blondeau, also known as Gébé, was born in Villeneuve-Saint-Georges and debuted as an illustrator in magazines like La Vie du Rail and L'Almanach du Cheminot' in the mid-1950s. He became one of the most loyal collaborators of the publishing house Le Square in the early 1960s. He was a frequent contributor to Le Square's magazines Hara-Kiri, Hara-Kiri Hebdo and Charlie Hebdo and was chief editor of Hara-Kiri from 1969 to 1985. He was the author of various photo-novels and short stories, and creator of the character 'Berck' (1964). Much of this work has been collected in albums by Editions du Square and later Dargaud: 'Il est Fou', 'Il est trop Intellectuel' and 'Qu'est-ce que je Fous là'.
