Louis de Beaufront

Who was Louis de Beaufront?

Marquis Louis de Beaufront, whose real name was Louis Chevreux 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.

Beaufront first discovered Esperanto in 1888 and in 1889 founded Société Pour la Propagation de l'Espéranto. In 1900, he wrote the Commentaire sur la grammaire espéranto.

He was chosen to represent unmodified Esperanto before the Committee of the Delegation for the Adoption of an International Auxiliary Language, attending the meetings of the Delegation Committee in October, 1907. While ostensibly representing Esperanto before the Committee, he was secretly secondary author after Louis Couturat of the original Ido project which impressed the Delegation Committee and led to the reform of Esperanto by the Committee's Permanent Commission. Letters that are kept in the Department of Planned Languages and Esperanto Museum in Vienna show that he denied any co-authorship of Ido.
