 The concept was first developed in 1903 by Italian mathematician Giuseppe Peano, under the title Latino sine flexione.He wanted to create a "naturalistic" international language, as opposed to an autonomous constructed language like Esperanto or Volapuk which were designed for maximal simplicity of lexicon and derivation of words.Peano used Latin as the base of his language, because at the time of his flourishing it was the "de facto" international language of scientific communication.
