Claudius Colas

Claudius Colas (29 November 1884 in Saint-Huruge, France – 11 September 1914 in Battle of the Marne) 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.
