A friend of Lord Halifax, he was also a Minister for education in 1941 under the Vichy Regime, and was as such the only member of the government to be present at the funeral of the philosopher Henri Bergson.
A devout Catholic, he attempted to eradicate the anti-religious feeling in educational circles and consequently closed the "Écoles Normales", which had been created in each "département" by the François Guizot law of 1833 to prepare teachers for elementary classes, replacing them with "Instituts de formation professionnelle". The anti-clerical Collaborationists opposed him however, and he had to step down (he was replaced by the historian Jérôme Carcopino); his reform was eventually abolished and the "Écoles Normales" were recreated.
