Weiss was born in Vienna, and graduated in German and English Studies from the University of Vienna. In 1933 she travelled to Shanghai, a city that before World War II attracted many European émigrés including revolutionaries from the Spanish Civil War, Jews and other refugees escaping the Nazis. She decided to stay, as did many others, and became fascinated by the social and political goals of the unfolding Chinese Revolution. Initially Weiss worked as a freelance journalist in Shanghai. Later she became a teacher at the Jewish School in Shanghai, at the School of the Chinese Committee of Intellectual Cooperation, and at the West China Union University. After working briefly as a secretary at the Canadian embassy in 1944, she became a correspondent at the United Nations Picture News Office in 1945 and joined the China Welfare Fund. One year later she took up a post at the Radio Division of the United Nations Organization in New York. Weiss worked as a teacher at the Jewish School in Shanghai, and married Yeh Hsuan, a Chinese engineer, with whom she had two children and went to the U.S. so he could pursue studies at MIT. Once the Chinese Revolution reached a climax in 1949, however, Weiss returned with her children to China, leaving Yeh in the U.S. After she returned to China she became a lecturer for the Verlag für fremdsprachige Literatur in Beijing from 1952 to 1965. In 1965 she worked as a journalist for "China im Bild". Ruth Weiss was one of about one hundred foreign-born residents to receive Chinese citizenship in 1955. In 1983 she was named one of eleven foreign experts by the Communist Party of China that were part of membership of the Chinese People's Political Consultative Conference. She died in Beijing, aged 97.
