Obituary

Eric R. Cosman, Sr, of Belmont, MA, passed away July 17, 2017. He was a Professor of Physics, Emeritus at the Massachusetts Institute of Technology (MIT). Dr. Cosman received a bachelor’s degree in Mathematics (1963) and a doctoral degree in Physics (1966), both from MIT. His early research career focused on nuclear physics including nuclear reactions, isobaric analog and shape-isomeric nuclear states. Later, his research transitioned to biomedical physics. Dr. Cosman supervised the Bachelors, Masters, and Ph.D. theses of numerous students at MIT during his active years as Professor from 1966 until 1991. From 1969 until 1991 he was also Scientific Director of Radionics, Inc. In 1991 he became Professor Emeritus, and in the same year succeeded his father, Bernard Cosman, as President and CEO of Radionics. In the year 2000, he sold Radionics to Tyco, Inc. Throughout these years, Dr. Cosman was the world’s leading authority on radiofrequency generation in medicine, intracranial pressure sensors and models, stereotactic methods, and radiosurgery. He invented and developed numerous techniques and instruments in these fields, including dozens of models of RF generators and electrodes for neurosurgery, pain therapy, and tumor ablation, the Cosman-Roberts-Wells (CRW) which was the world’s leading stereotactic frame in neurosurgery, and pioneering mechanical and software applications in stereotactic radiosurgery and image guided navigation. In 2004, he founded Cosman Medical to advance radiofrequency technology in pain management and neurosurgery, and he continued to publish scientific articles in that field. In 2011, he was succeeded as CEO of Cosman Medical by his son, Eric R. Cosman, Jr. In the year 2016, Cosman Medical was sold to Boston Scientific. Professor Cosman was the author of over 100 scientific publications in Nuclear Physics and Biomedical Physics, and the author of over 150 U.S. and foreign patents and patent applications.

Professor Cosman was born in Boston, MA, on May 9, 1942 to Bernard J. Cosman and Lillian A. (Spracklin) Cosman. He grew up in Arlington, MA, with siblings Lillian S. Cosman, Ann (Cosman) Walter, Walter Cosman (died 1946), and Hope (Cosman) Alminana. He attended the Bishop elementary school, Junior High East, and High School in Arlington. He was a brother of the Phi Beta Epsilon fraternity at MIT. Professor Cosman and his wife Helga H. (Just) Cosman raised a family in Belmont, MA, and lived there for over 40 years. He is survived by Helga; their four children Eric R. Cosman Jr, Christina M. Cosman O’Sullivan, Niels J. Cosman, and Sonia H. Cosman; and five grandchildren Tadhg E. O’Sullivan, Eden E. O’Sullivan, Matilda M. O’Sullivan, Bjorn B. S. Cosman, and Isla G. H. Cosman.
