After fleeing Silesia at the end of World War II, she met Rüdiger Eichholz in western Germany and married him.
Her work there led to the birth of the Sri Lankan Esperanto movement and the Sri Lankan Esperanto Center in Nugegoda, which was founded by her student Daniel Balasingham Jesudason.
Eichholz designed En Novan Mondon ("Into a New World") (1984), a complex Esperanto course for children using the Cseh method.
She also wrote an English-language brochure on equitable bilingualism in Canada (1982), collaborated with her husband Rüdiger Eichholz in compiling the extensive anthology Esperanto in the Modern World (1982), and created instructional card games.
She supported her husband's work on glossaries, revising, for example, the rough draft of the Esperanta Bildvortaro ("Esperanto Picture Dictionary") (1988).
