Louis Chevreux (3 October 1855, Paris – 8 January 1935, Thézy-Glimont), commonly known as Louis de Beaufront, was a major influence in the development of Ido, an international auxiliary language. Beaufront was initially an advocate of Esperanto and was largely responsible for its early diffusion in western Europe as well as one of its first French proponents.
