François-Guillaume Barrillon

François-Guillaume Barrillon (1804–1885) was a French author whose surviving trace is mostly bibliographic rather than biographical. Library and catalog records confirm his name, dates, and authorship of La réforme postale en France, showing him as a writer engaged with practical civic questions rather than fiction or literary celebrity.

Because readily available sources are sparse, only a small outline can be given with confidence. What does come through is a picture of a 19th-century writer interested in reform and public life, and whose work has been preserved through major cataloging institutions.

No reliable portrait image could be confirmed from the sources reviewed.
