1874–1953
A meticulous French librarian and historian, he devoted his career to medieval sources and helped bring early French kings and chronicles into clearer view. His work is especially tied to the study of manuscripts and the history of the early Capetian and Carolingian periods.

by Philippe Lauer
Born in Thorigny-sur-Marne on December 2, 1874, and dying in Paris on February 3, 1953, he was a French librarian and historian. Sources agree that he trained at the École des chartes and the École des hautes études, then spent two years at the École française de Rome before returning to France.
He joined the manuscript department of the Bibliothèque nationale, where he remained until retirement. His scholarly work centered on medieval France, with notable studies and edited texts on figures such as Louis IV and Robert the Pious, as well as on manuscripts and historical sources.
That background gives his books a dependable, archival feel: careful with documents, attentive to chronology, and deeply rooted in primary materials. For listeners interested in medieval history, he stands out as a patient guide to the world of early French kings, chronicles, and manuscript culture.
