The digital collection La 1ère Guerre vue de Paris has been created by Odile Gaultier Voituriez. The collection gives an edition of 1020 letters exchanged during the First World War between two men in Paris, Étienne Bandy de Nalèche (1865-1947), a former diplomat who became the owner and editor-in-chief of the influential Journal des Débats, and Pierre Lebaudy (1865-1929), an industrial entrepeneur, philantrope and art collector. The original letters are mainly kept at the Archives d’histoire contemporaine, Centre d’histoire of Sciences Po in Paris [Fonds Étienne de Nalèche]. The list of other relevant sources and the extensive bibliography merit attention. The letters are posted in a sequence which gives you a day-to-day idea of this correspondance. You can select letters by month of publication.
