Claudius Colas writing language Esperanto
Claudius Colas (Saint-Huruge, France, 29 November 1884 - Battle of the Marne, 11 September 1914). , also known as Profesoro V. Esperema, was a French Esperantist. In 1910, he created the constructed language Adjuvilo, which was a complete language that was never meant to be spoken but instead an effort to help create dissent in the then-growing Ido movement.  In 1910, he co-founded IKUE, the foremost organization of Catholic Esperantists in the world.
He died during the early days of World War I.
