author
A little-known early Esperanto writer, remembered for a travel narrative that turns a journey through Russia into a lively glimpse of language, culture, and friendship. The surviving record is sparse, which gives the work an added sense of curiosity and discovery.

by A. Rivier
Very little confirmed biographical information about this author appears to survive in the readily available public record. What can be verified is that A. Rivier is credited as the author of En Rusujo per Esperanto, published in 1911 in Moscow.
That book is a travel narrative in Esperanto, describing a journey in Russia and the author's encounters with people and places through the shared use of the Esperanto language. Today, the work stands as an interesting example of early Esperanto writing and of how the language was used not just for theory or correspondence, but for real travel and human connection.
Because dependable sources on the author's life are limited, it is safest to let the book speak for the writer. Readers interested in early international travel writing or the history of Esperanto may find A. Rivier especially intriguing for that reason.
