Rüdiger Eichholz (May 1, 1922 in Stralsund, Germany – September 5, 2000 in Cobourg, Ontario), was a Canadian physicist[citation needed] and Esperantist and a member of the Esperanto Academy.
The Eichholz couple educated their son Alko and their daughters Suna and Brila as native Esperanto speakers.
[1] Though he did not always agree with decisions of the association, he remained a passionate collaborator of the KEA for the rest of his life and was elected an honorary member in 1995.
In 1988, Eichholz published the Esperanto picture dictionary (Esperanta Bildvortaro), a project on which he attracted no fewer than 143 collaborators in translation.
He printed textbooks written by Vilma, an English-language version of Edmond Privat's The Life of Zamenhof and many other books.
Elected as an Esperanto Academy member in 1976, Eichholz led its technical and specialized terminology section.
Vilma, who had stayed behind while Rüdiger went to Europe, was exhausted; the doctor diagnosed liver cancer.
After several months' battle with cancer, Rudi's wife and close collaborator died in July 1995.
