From Marion Morris Bush:

It is with great sorrow that I advise you of the passing of Susan Morris Butterfass on August 31, 2021, after a brief illness complicated by her fight with multiple myeloma. She was a talented and much-loved educator, specializing in nature studies and outdoor education, and was also an artist, excellent cook, linguist, and much more. She is survived by her husband of 50 years, Stephen, two daughters Alison (John) Zagat and Ariel (Michael) Yagudayev, three grandchildren, her twin sister, and her brother Richard. We are all devastated.
