[Doctor Zamenhof (1859-1917): a physician "who hopes"!(II)].

A previous paper detailed the life and the works of Louis-Lazare Zamenhof (1857-1917), a young physician, born in Lituania, of Jewish origin, specialiazed in ophtalmology. Zamenhof created a new universal language he called "Esperanto". The study continues Zamenhof's biography, from 1905, date of the first international esperantist congress, at Boulogne-sur-Mer, in France to 1917, year of Zamenhof's death, during World War I. The paper will restitute Zamenhof's ideology in the history of the ideas of the XXth century, such as nationalisms, internationalism, pacifism and universalism of Human Right.
