A risky bet given that its 21-year old founder was called Maurice Kahane, an atheist Jewish man who would then adopt the name of his mother, Girodias. The Chêne specialized itself by the edition of art books and literature. The Editions du Chêne would become a branch of the Hachette group in 1951. The edition of art books would then adopt pride of place. George Herscher takes over the Hachette house with enthusiasm in 1971.
