Dr. Morris Simon, MB, BCH, (1926–2005) was a South African-born American radiologist, professor, and inventor. His medical practice was based primarily at Beth Israel Deaconess Medical Center, Boston, where he specialized in chest radiology.[1] He is also credited with a number of medical inventions, including a flexible filter for dissolving blood clots, and innovations that streamlined patient care and records holding.[2]

Early life

Morris Simon was born in Johannesburg, South Africa.[2] He was the son of working-class Lithuanian Jewish immigrants, and the older brother of the writer, playwright, and director Barney Simon. He was the father of four boys, including the American artists Adam Simon Jason Simon, publisher Dan Simon, and teacher and labor organizer Mark Simon.[2]

Education and career

Simon received his undergraduate and medical degrees from Witwatersrand University, South Africa. In 1949, together with his wife Josephine, they moved to London, where he received his training in Radiology and imaging at the Royal College of Physicians and Surgeons.[1]

In 1958, he was recruited by

Radiologist in Chief and Director of Clinical Radiology at the medical center.[2] Following his long teaching career at Harvard Medical School, Simon retired as Professor of Radiology Emeritus in 1997.[1]

Throughout his career, Simon published a number of articles and medical scholarship, which ranged in focus from radiological approaches to pulmonary hypertension, innovative CT imaging approaches to pulmonary arteries and the lungs, and early detection of pulmonary embolisms.[3][4][5][6]

Death

Morris Simon died of cardiac arrest at age 79 on January 17, 2005, at his home in Boston. At the time he was serving as Professor Emeritus at Harvard Medical School, and also the Radiologist in Chief and Director of Radiology at the Beth Israel Deaconess Medical Center, Boston.[1]

Legacy, inventions, and innovations

Simon is credited as inventing and developing a number of advances in the medical field.

Simon-Nitinol Vena Cava Filter

Simon participated the first nationwide collaborative pulmonary embolism trial in the early 1970s. It was in this context that he developed a widely used flexible filter to catch and dissolve clots in the bloodstream, the "Simon-Nitinol Vena Cava Filter."

Nitinol and which had thermal-memory properties. This alloy was previously used in military and aerospace contexts: at different temperatures its shape can be manipulable, when cooled, or spring into a predetermined shape when warmed.[2]
Simon modified the alloy for use at or below body temperature.

In its colder form, the filter is more compact. It is inserted through a catheter into the patient, then expands when it reaches the temperature of the body.

nitinol."[2]

Simon-Leeming Medical Classification

Simon also implemented the Simon-Leeming Medical Classification, which was used across the entirety of

Beth Israel Hospital. It became the basis for the CLIP (Coded Language Information Processing System).[1] The network implemented at Beth Israel allowed for quick retrieval of files and data based on anatomy, pathology, and findings—decades before the commonly used systems of digital patient file records had been put in place.[1]

Additional innovations and honors

Simon is also credited for developing a number of other technical innovations, including a second blood filter that is meant to be removable, a needle used in

biopsies, and a system designed to semi-automatically dispense specific doses of multiple medications to patients, in particular elderly ones.[2] He also developed a combination ruler and magnifying caliper, as well as an ornamentally designed body caliper.[7]

In January 2006, the Department of Radiology at Beth Israel Deaconess Medical Center dedicated their most advanced chest readings room in his memory as the "Simon Room."[1]

Records of Morris Simon's medical research are held in the Morris Simon Papers, 1934–2005 collection at the

Countway Library of Medicine in Boston, Mass.[8]
