The German-born Jewish mathematician Emmy Noether (1882-1935) published 43 research papers. Albert Einstein eulogized her in a letter that appeared in the New York Times on May 5, 1935, where he is quoted as saying, "In the judgment of the most competent living mathematicians, Fräulein Noether was the most significant creative mathematical genius thus far produced since the higher education of women began."
