Bichelonne gained an early reputation for his brilliant organisational skill as well as his photographic memory. In 1937, he became member of the cabinet of the minister for public works, Henri Queuille. In 1939, he became chief of staff to Raoul Dautry, then Defence Minister. He was a member of the French delegation in the armistice commission. Following the establishment of Vichy, Bichelonne was, in September 1940, appointed head of the Office central de repartition des produits industriels, a body that determined how raw materials would be proportioned between the newly established corporatist bodies in charge of each industrial sector. Along with the likes of Jacques Barnaud, François Lehideux and Pierre Pucheu, Bichelonne was a member of a group of technocrats who held important positions in the early days of the Vichy regime. Like Pucheu he was devotee of Saint-Simonianism, the belief in industrialisation as the motor of progress in society, a belief that was not shared by the rural traditionalist Philippe Pétain. In the government of Pierre Laval the Ministry of Industry was headed by Jean Bichelonne with Henri Lafond as General Secretary for Energy and René Norguet as General Secretary for Industrial Production. Lafond's Energy secretariat included sections for mines, steel, gas/electricity and fuel. As Minister of Industrial Production, Bichelonne faced the problem of demands for slave labour from the Nazi Labour Deployment Minister Fritz Sauckel, and the impact it was having on French industry. He managed to overcome this difficulty by securing an agreement with Albert Speer in September 1943 to the effect that the entire French industrial sector would be Sperrbetrieben, making it effectively off limits to Sauckel. Bichelonne was one of the cabinet members taken under SS guard from Vichy to Belforton the night of 17–18 August as the Nazis desperately sought to maintain the collaborationist government by any means necessary. Moved to the Sigmaringen enclave, Bichelonne fell ill and was sent to the SS hospital at Hohenlychen.
Death
Bichelonne died on 22 December 1944. It was officially recorded that he died of a pulmonary embolism, but unsubstantiated rumours suggested that he may have been assassinated. These rumors are made reference to by Albert Speer in his book titled Inside The Third Reich whereby Speer was hospitalized and later on diagnosed with a pulmonary embolism. Coincidentally, the same doctor who would treat Bichelonne treated Speer and happened to maintain a close friendship with Heinrich Himmler. https://books.google.ca/books/about/Inside_the_Third_Reich.html?id=XLSa_RIDHMUC&redir_esc=y
