It was through model-making that this mathematics teacher became France's greatest endurance expert. This vocation happened to coincide with the 1976 launch of the magazine AUTOhebdo, of which he was to become a fixture. Jean-Marc Teissedre is also the author of seminal works on this motorsport discipline, such as the official annual of the 24 Hours of Le Mans, in addition to penning biographies of drivers such as Henri Pescarolo (ETAI) and Bob Wollek (Le Mans Racing) and multiple publications on the 24 Hours, including Les 24 Heures du Mans 1923-2010 (Le Mans Racing). Having discovered the 24 Hours of Le Mans at the age of five, Thibaut Villemant subsequently joined AUTOhebdo in 2009. He was quickly promoted to senior reporter and served as deputy editor-in-chief until 2021. Together with Jean-Marc Teissedre, he is the author of the official 24 Hours of Le Mans annual, in addition to which he has published other works on the event and regularly consults for television.
