Livre fondateur, Le Siècle de Louis XV sortit le XVIIIe siècle de l’ombre et mit en lumière la figure de ce roi jusqu’alors mal connu. Tous les grands biographes ont suivi les traces de Pierre Gaxotte, sans toujours avoir son talent.
Gaxotte was born in Revigny-sur-Ornain, Meuse. He began his career as a history teacher at the Lycée Charlemagne and later worked as a columnist for Le Figaro. Over the course of his life he authored numerous historical studies, and was elected to the Académie française in 1953.
He is famous for his critical vision of the French Revolution, notably in The French Revolution (1928)and for his rehabilitation of the French 18th century (Louis XV's Century, 1933). He is also known as a right-wing journalist of the Entre-deux-Guerres period.
