Lidia Zamenhof learned Esperanto as a nine-year-old girl. By the age of fourteen she translated from Polish literature; her first publications appeared several years thereafter. Having completed her university studies in law in 1925, she dedicated herself totally to working for Esperanto. In the same year during the 17th World Congress of Esperanto in 1925 in Geneva she became acquainted with the Baháʼí Faith. Lidia Zamenhof became secretary of the homaranistic Esperanto-Society Concord in Warsaw and often made arrangements for speakers and courses. Starting at the Vienna World Congress of Esperanto in 1924 she attended almost every World Congress (she missed the 1938 Universala Kongreso in England). As an instructor of the Cseh method of teaching Esperanto she made many promotional trips and taught many courses in various countries.
