Esperanto is the brainchild of Dr. Ludwig Zamenhof, the Polish ophtalmologist and linguist.
In 1887 he published a textbook for his newly-devised language meant to serve as a bridge between people the world over.
Since then, tens of thousands of people have used Esperanto in a wide variety of ways.
Internet radio broadcasts and podcasts from China, Havana and Vatican City can be heard regularly. Postage stamps have appeared in Esperanto. Annually a convention of Esperanto-speakers from around the world takes place in a different country each year.
