Claudius Colas
Claudius Colas 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.
