Michel Duc-Goninaz

[2] A member of the World Esperanto Youth Organization (TEJO) during the 1950s, he served as co-editor of La Folieto, distributed mainly among young Esperantists of Île-de-France.

Notably, he compiled Vocabulaire Espéranto (Laŭtema esperanta franca vortareto), a thematic French-Esperanto dictionary published by Ophrys in 1971 (2nd edition, 1990), and he adapted Alexander Pushkin's play The Stone Guest into Esperanto as La Ŝtona Gasto.

Duc Goninaz is now a lecturer at the International Academy of Sciences in San Marino and is a regular contributing editor to the Esperanto-language monthly magazine Monato.

In 2002 the journal La Ondo de Esperanto named Duc Goninaz as Esperantist of the Year in recognition of his work as chief editor for the dictionary revision.

Another revised edition (2005) corrected numerous typographical errors, many of which had been noted by Esperanto grammarian and lexicographer Bertilo Wennergren.
