Calmann-Lévy, founded in 1836, is one of the oldest French publishers and is responsible for bringing acclaim to popular fiction with such authors as Balzac, Dumas, Flaubert, Hugo and Stendhal. Moving with the times, it turned to nonfiction and essays. Its Liberté de l’esprit collection was created and edited by Raymond Aron in the twentieth century; it has now been relaunched. In 1950, it published Le Journal d’Anne Frank (The Diary of a Young Girl). Today, Calmann-Lévy publishes a varied list of well-known authors including Guillaume Musso, Yann Queffélec, Laurent Gounelle, Michael Connelly, Donna Leon, Donato Carrisi, Thomas Harris, Antony Beevor, Ronan Farrow, Martin Amis and Plantu, in a wide variety of genres such as French and foreign fiction, detective novels and essays.
