author
b. 1814
A 19th-century French writer remembered for historical and biographical works, including a study of Chateaubriand and Madame de Custine built around unpublished correspondence. Little biographical information about him appears to be widely available today, which gives his surviving books a certain archival charm.

by vicomte de François-René Chateaubriand, Émile Chédieu de Robethon, marquise de Delphine de Sabran Custine
Émile Chédieu de Robethon was a French author born in 1814. Surviving catalog and library records confirm his name and date, and they show that he wrote in French on literary and historical subjects.
One of his best-documented works is Chateaubriand et Madame de Custine: épisodes et correspondance inédite, a book centered on François-René de Chateaubriand, Madame de Custine, and their correspondence. From the title and library descriptions, his writing seems aimed at readers interested in biography, letters, and the personal side of literary history.
Beyond that, readily accessible sources offer only a sparse outline of his life. That relative obscurity makes him the kind of author known mainly through the works he left behind rather than through a well-preserved public biography.
