L. L. Zamenhof

Creator of Esperanto (1859–1917)

L. L. Zamenhof (1859–1917) was the creator of Esperanto, the most widely used constructed international auxiliary language. Zamenhof published Esperanto in 1887, although his initial ideas date back as far as 1873. He grew up fascinated by the idea of a world without war and believed that this could happen with the help of a new international auxiliary language (IAL).
