1779–1848
Known today mainly through a published exchange of letters with François-René de Chateaubriand, this French marquise left behind a glimpse of literary and emotional life in the early nineteenth century. Her surviving reputation is intimate rather than monumental, shaped by correspondence rather than a large body of standalone books.

by vicomte de François-René Chateaubriand, Marquise de Louisa Phillipa Rioufol d'Hautevill Vichet
Born in 1779 and dead in 1848, she is identified in library and public-domain records as the Marquise de Vichet, Louisa Phillipa Rioufol d'Hautevill(e). The work most clearly linked to her is Correspondance de Chateaubriand avec la marquise de V...: Un dernier amour de René, a volume of correspondence published with François-René de Chateaubriand.
Reliable online sources about her are quite sparse, so many biographical details remain hard to confirm. What can be said with confidence is that her name has endured through these letters, which connect her to one of the central figures of French Romantic literature and preserve a personal, historically interesting voice from that period.
Because the available record is limited, she is best approached as a historical correspondent and literary presence rather than as a fully documented public author in the modern sense.
