 In liaison with Louis Darquier de Pellepoix, Bonnefoy expelled Jewish teachers from universities and created a chair on the history of Judaism at the Sorbonne University, entrusted to Henri Labroue.After Pierre Laval dismissed the team of "Je Suis Partout" from Radio-Vichy in September 1940 due to their extremism, he entrusted the direction of information to Bonnefoy, who became responsible for developing the themes of the "Révolution Nationale" over the radio.Upon the return of Laval to power in April 1942, Bonnefoy replaced Paul Marion—then in charge of Information for the Vichy government—as the head of press control.
