1779–1848
Best known today through a volume of letters exchanged with François-René de Chateaubriand, this French marquise appears as a thoughtful, emotionally vivid presence in a late chapter of Romantic literary history. Her surviving work offers readers a rare glimpse of intimate conversation, feeling, and social life in early 19th-century France.

by vicomte de François-René Chateaubriand, Marquise de Louisa Phillipa Rioufol d'Hautevill Vichet
Little seems to be widely documented online about this author beyond bibliographic records, but available sources identify her as Louisa Philippa (or Louisa Phillipa) Rioufol d'Hauteville, marquise de Vichet, born in 1779 and died in 1848.
She is chiefly associated with Correspondance de Chateaubriand avec la marquise de V..., a collection of letters linked to François-René de Chateaubriand and published after their exchange. That connection has kept her name alive for modern readers, not as a major standalone public figure with an extensively preserved biography, but as an important participant in a literary and personal correspondence.
Because confirmed biographical detail is scarce in the sources I could verify here, it is safest to remember her as a French aristocratic letter-writer whose surviving presence comes through that correspondence and the emotional, conversational world it preserves.
