André Vaillant

André Vaillant (November 3, 1890 – April 23, 1977), was a French linguist, philologist and grammarian who also specialized in Slavic languages.

He was born in Soissons. After studying at École Normale Supérieure in Paris, he became professor at the Collège de France, acting as a Chair of Slavic Languages and Literatures in 1952.

In Russia, he studied manuscripts written in Old Church Slavonic. He worked at the Institute of Slavic Studies of Paris. He collaborated in the drafting of the Revue d'études slaves (Journal of Slavic Studies) which served as the basis for the development of his comparative grammar of Slavic languages.

He wrote twenty books including the six-volume Comparative Grammar of Slavic languages (Grammaire comparée des langues slaves), the two-volume Handbook of Old Church Slavonic (Manuel de vieux-slave) and a grammar of Serbo-Croatian together with Antoine Meillet.

He translated and published many liturgical texts written in Church Slavonic.

He died in Paris.
