L. L. Zamenhof writing language Russian
For two years, he tried to raise funds to publish a booklet describing the language, until he received the financial help from his future wife's father. In 1887, the book titled Международный язык. Предисловие и полный учебникъ (International language: Introduction and complete textbook) was published in Russian under the pseudonym "Doktoro Esperanto" (Doctor Hoper, or literally "Doctor One Who Hopes"). Zamenhof initially called his language "Lingvo internacia" (international language), but those who learned it began to call it Esperanto after his pseudonym, and this soon became the official name for the language. For Zamenhof, this language, far from being merely a communication tool, was a way to promote peaceful coexistence between people of different cultures.
