Zamenhof-Esperanto object

The first Zamenhof-Esperanto object was the ship Esperanto, constructed and launched in Spain in 1896, nine years after the language's birth. The 1934 Encyclopedia of Esperanto listed approximately 50 towns and cities in which Esperanto or Zamenhof have been honored. In 1997, a German Esperantist, Hugo Röllinger, published a book titled Monumente pri Esperanto – ilustrita dokumentaro pri 1044 Zamenhof/Esperanto-objektoj en 54 landoj ("Monumentally about Esperanto – an illustrated documentary of 1,044 Zamenhof-Esperanto objects in 54 countries") and until his death in 2001 he listed a total of 1,260 such objects.[1] It is he who coined the acronym ZEO. Currently, Robert Kamiński of Poland is the person charged with the registration of ZEOs by the Universal Esperanto Association.[2]
