"The key for a common language, lost in the Tower of Babel,
can only be found in the use of Esperanto."
Leo Tolstoy, 1828-1910
Esperanto is the most widely spoken constructed international auxiliary language. It was created
by Polish ophthalmologist L. L. Zamenhof in 1887, when he published a book detailing the
language, Unua Libro ("First Book"), under the pseudonym "Dr. Esperanto". The word
esperanto translates into English as "one who hopes".
