Stephen N. Wiener, M.D., beloved husband, father and grandfather, and a leading physician in the field of nuclear medicine, passed away on Aug. 2 at his summer home in Brevard, N.C., at age 92. Husband of 67 years to June Wasser Wiener, and father of Clifford and Andrew. Stephen was a dedicated and innovative radiologist who spent his life in service to his profession and cared deeply for his family.

Stephen Newton Wiener was born on Feb. 26, 1927, in Providence, R.I. He attended Brown University, from which he graduated Phi Beta Kappa in 1949, and was a U.S. Navy veteran (1945 to 1946). Dr. Wiener earned his medical degree at Hahnemann Medical College of Philadelphia in 1953, following which he served his internship and residency at Mt. Sinai Hospital in Cleveland.

During a 44-year career (1953-1997) at Mt. Sinai Hospital, Dr. Wiener served as director of the department of radiology, president of the medical society and chairman of the medical advisory board. He was also the first physician elected to the hospital’s board of trustees.

In the 1970s and 1980s, Dr. Wiener led Mt. Sinai’s radiology department to national prominence during a period of rapid scientific and technological advances. Under his leadership, Mt. Sinai was one of the first hospitals in the United States to acquire a magnetic resonance imaging scanner, and Dr. Wiener and his colleagues performed some of the first MRI experiments. The work was later shared with the National Institutes of Health.

Dr. Wiener served as president of the Cleveland Radiological Society and was a fellow of the American College of Radiology. He published numerous articles in medical and technical journals in the fields of nuclear medicine, ultrasound, computed tomography and MRI, served as a clinical professor at Case Western Reserve University, and was an examiner, nuclear radiology, for the American Board of Radiology.

Dr. Wiener was an avid tennis player and a classical and jazz piano enthusiast who enjoyed playing the piano and attending concerts. He also enjoyed singing in a local a cappella group in Cleveland, the Sleepless Knights. During his retirement, having moved from Cleveland to a winter home in Treasure Island, Fla., he added boating to his recreational activities, and at age 83 turned from tennis to pickleball, later helping to establish courts at his retirement community in St. Petersburg, Fla., to which he and June moved in 2014. He remained active in the community throughout his retirement, including teaching computer skills to seniors and designing websites for nonprofit organizations. His sense of humor and integrity were gifts to all who knew him. His caring spirit will be greatly missed.

Dr. Wiener is survived by his wife, June; sons Clifford of Cleveland and Andrew of Oakland, Calif.; grandchildren, Claire and Evan; and brother, Howard of La Jolla, Calif.

Dr. Wiener requested that no services be held and that any contributions be made to the Stephen N. Wiener Family Scholarship Fund at Brown University.
