This was interesting and I was waiting for H.G. Wells to show up, which he did. For anyone interested in the far reaches of science-fiction literature, and much else, see "The Encyclopedia of Science Fiction". It is used to be a thick book but is now online, and includes a decent entry on Maurice Renard [1]. I often worry about the quality of the translation for works not in English though.
