Dr. Glendon E. Rayson, a retired Baltimore internist who had worked at Johns Hopkins Hospital, died July 12 of internal bleeding at Memorial Hospital South in Hollywood, Fla. He was 96.
Glendon Ennis Rayson, the son of a schoolteacher and a homemaker, was born and raised in Oak Park, Ill.
He was a graduate of the University of Rochester and enlisted in the Army in 1943, which sent him to medical school at Temple University in Philadelphia, where he earned his medical degree.
Dr. Rayson continued his medical education until 1950, when he enlisted in the Air Force Medical Corps and served as a flight surgeon during the Korean War.
After being discharged with the rank of captain in 1953, he completed his internship at St. Luke's Hospital in Chicago, and from 1956 to 1958, he was physician-in-charge at Contagious Disease Hospital, also in Chicago.
Dr. Rayson also completed a fellowship in gastroenterology and endocrinology at St. Luke's, and taught at the University of Illinois College of Medicine.
During the Vietnam War, he did four tours of duty — 1968, 1971, 1972 and 1973 — in Vietnam as a volunteer physician working with the Army Medical Corps, treating wounded troops as well as civilians.
In 1966, he came to work as a research assistant at the Johns Hopkins University. In 1971, he began working as an internist at Hopkins Hospital until entering private practice in 1982.
Dr. Rayson returned to Vietnam in 1993 as a member of the Citizens Ambulatory Delegation, and later in the 1990s, joined medical professionals who traveled to Cuba to study the country's health care system.
He retired in 2001.
In 2009, the former North Charles Street resident moved to Lakeview, an assisted-living facility in Hollywood, Fla.
He enjoyed singing and writing short stories and poetry.
His wife of a few months, the former Sally Weida, a registered nurse at Hopkins, died in 2007.
Plans for a memorial service to be held in Lake Worth, Fla., in the fall, are incomplete.
He is survived by several nieces and nephews.
