Ido
The group met at the Collège de France during the month of October 1907 and examined many international language projects, presented by representatives of their authors. They quickly came to the result that there were only two international language projects worthy of interest: Esperanto and Idiom Neutral. However, on the last day, the Delegation chose "Ido". The author of this language was unknown to the Delegation (later it would be discovered that Couturat was the creator). Ido was a kind of combination between a kind of Esperanto and Idiom Neutral.
