He began his career as the head of the financial analysis department of the weekly magazine Entreprise; he then created two management journals: Enseignement et gestion and the Revue Française de Gestion. After that he took over the head of the avant-garde monthly Mode international. Several years later he edited the magazines Collections, Décoration, and Mariages. He moved to Votre Beauté, a magazine that François Mitterrand edited at the beginning of his career. He later joined the Hachette Group, which is now the Lagardère Group, as international editor of Elle and Elle Décoration. He also created Cousteau Junior and Max. He was until 2012 the director of Marie Claire maison and Marie Claire travel magazines in Milan.
Art historian
This interest for art came to be in 1969 after his meeting with the sculptor Edmond Moirignot, with whom he became a friend, later his guardian, and now the executor of his will. He published an important monograph on the sculptor Jean-Baptiste Carpeaux in 1987. Intensive studies on the history of sculpture and French drawing followed. More recently he published two books on the Nabis and the Fauves, that is, those schools or movements that catapulted art into modernism at the turn of the century.
Rimbaud
This is how Raphaël Sorin presented him in l'Express when his Dictionnaire Rimbaud came out in 1991. A late calling though: after quoting a quotation of Arthur to his professor Izambard in an editorial in Max—the magazine that he directed at the time, he received so much mail that he decided to go into more depth on the subject. He continues to do so—publishing his findings on a regular basis. His vision of Rimbaud is far from the usual clichés of the damned poet. According to him, the poet is too intelligent to be incoherent. His poems always have a meaning, are coherent, and have a mission. Rimbaud is determined and wilful. He completely gives himself over to poetry because he is certain that it can be life changing. Une Saison en enfer, which is a quest for salvation, is also a written essay of a new bible for modern times. The poetry is thus a means and not an end, a tool, at the service of a very spiritual and humanist ideal. So, when he finds himself persuaded of its inefficiency—it being much slower than he had hoped—he discards it and moves on to something else. The vision of Claude Jeancolas is very human, and his Rimbaud, with his dreams, doubts, anger, lassitude and failures is brought closer to the reader, which explains the success of this biography with the general public. He has also redeemed his well criticised mother, Vitalie Rimbaud, in a biography that shows the intense love that attached this mother to her preferred child; and conversely, the necessity of this mother for Rimbaud to be able to become the man that we know.
