Eichholz was born in 1926 in Silesia, Weimar Germany. After fleeing Silesia at the end of World War II, she met Rüdiger Eichholz in western Germany and married him. In the early 1950s, the pair emigrated to Canada. They had three children, who they raised as native Esperanto speakers.
In 1979, Eichholz travelled to Sri Lanka and published a 12-page booklet about her experiences: Impresoj de esperantistino en Srilanko ("Impressions of an Esperantist in Sri Lanka") (Ontario, 1979). She was probably the first foreign Esperantist to visit the island nation. 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.
In the 1990s, after the dissolution of the Soviet Union, she taught Esperanto in Kaliningrad, among other places.
She died of cancer on July 15, 1995[1] in Bailieboro, Ontario.
