Claudius Colas

Claudius Colas (also known by the pseudonym Profesoro V. Esperema) was a French Esperantist who lived from 1884 to 1914. 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.
