author
Known today mainly through a single French work preserved by Project Gutenberg, this little-known writer appears to have focused on practical questions of mail, transport, and public administration rather than fiction.
Very little biographical information about this author could be confirmed from the sources available during this search. Library listings identify M. Fenis as the author of Mémoire sur la réunion des trois services, des postes aux chevaux, de la poste aux lettres, et des messageries, sous une seule administration, a French work about bringing horse-post, letter-post, and coach services under one administration.
That surviving title suggests an author interested in how communication and transport systems were organized in France, and in the kind of policy debates that surrounded public services. No reliable source found here confirmed fuller personal details such as a complete name, life dates, or a verified portrait.
For readers, that makes M. Fenis an intriguing historical voice: not famous for a long literary career, but remembered for a focused contribution to the history of postal reform and administration.
