 Dr. Eleanor Harz Jorden, the author of Beginning Japanese, Parts 1 and 2, wrote the first pedagogical grammar of Japanese written by a linguist.She also coauthored the widely used Mastering Japanese textbook, along with the Foreign Service Language Institute, and Hamako Ito Chaplin.Colleagues in the field of Japanese pedagogy, such as Professor Mari Noda, say that Dr. Jorden was unusual in her time in that she insisted on the use of audio recordings to supplement the text-based grammar and vocabulary in her work.
