French philologist, born at Colmar in Alsace. Having held appointments at Douai and Lille, he was appointed professor of Sanskrit and comparative grammar in the university of Paris. A prolific and versatile writer, he is probably best known by the English translations of his Précis de Grammaire comparée de langlais et de lallemand and Précis du Grec et du Latin. Important works by him on India and Indian languages are the following: Manuel pour étudier le Sanscrit vedique (with A. Bergaigne, 1890); Éléments de Sanscrit classique (1902); Précis de grammaire Pâlie (1904); Les Littératures de lInde: Sanscrit, Pâli, Prâcrit (1904); La Magie dans lInde antique (1904); Le Parsisme (1905); LAgnistoma (1906). Obscure languages (such as Innok, Quichua, Greenland) and local dialects (Lexique étymologique du Breton moderne; Le Dialecte Alaman de Colmar) also claimed his attention. Le Langage Martien is a curious book. It contains a discussion of some 40 phrases (amounting to about 300 words), which a certain Mademoiselle Hélène Smith (a well-known spiritualist medium of Geneva), while on a hypnotic visit to the planet Mars, learnt and repeated and even wrote down during her trance as specimens of a language spoken there, explained to her by a disembodied interpreter. He died at Sceaux, near Paris, in February 1907.
