Born in Jamestown, Missouri, in 1928. Heyssel attended the University of Missouri and graduated from the St. Louis University School of Medicine in 1953, with an honorary doctor of science degree. Upon finishing two years of residency he spent 2 years (1956-58) as a Commissioned Officer in the US Public Health Service in Japan at the Atomic Bomb Casualty Commission (ABCC) in Hiroshima. He served as Head of the Internal Medicine clinic at a time when ABCC diagnosed and treated cases with leukemia caused by high radiation doses from the A-bomb. In the course of his stay, he and his associates reviewed all the leukemia cases, and published the first report using newly available dose measurements. He returned to Washington U for an additional year of Fellowship working under Carl Moore. In 1959 he joined the Vanderbilt faculty with appointments in Medicine (Hematology) and Nuclear Medicine, where he was Co-Director of the Nuclear Medicine Division with George Meneely in the conduct of Hematology, body composition and metabolism studies. Bob investigated new tracers for labeling platelets. He used Fe-59 to study red cell metabolism and lifespan using whole body counter, and blood sampling data. Dietary requirements for Vitamin B12 were established by measuring absorption and turnover of Vit. B12 with the whole body counter. Meneely left in 1962, and In 1964 Randy Brill joined Bob as co-Director of the Division. Imaging studies expanded and computer modeling of iron kinetics expanded in collaboration with colleagues from Engineering. Studies of reticulendothelial function in normal and diseased states were done in collaboration with the infectious disease colleagues.
In 1968, Bob was recruited to Johns Hopkins by David Rogers (new Hopkins Dean, and former Chair of the Vanderbilt Medicine Department), wherre he had an illustrious career. The Hopkins Gazette notes that: “Heyssel came to Hopkins in 1968 as associate dean of the School of Medicine and director of outpatient services, was named executive vice president and director of Hopkins Hospital in 1972, its president in 1982, and president and CEO of the Health System 1986.
He made major acquisitions and mergers, and launched both The Johns Hopkins Health System and the Johns Hopkins Health Plan, moving the institution into the world of managed care with a base of corporate clients, government contracts and tens of thousands of members. He created the Johns Hopkins Medical Services Corp. to retain control of the provider side of the enterprise when the plan was sold. Under his leadership, Hopkins acquired the failing Baltimore City Hospitals, expanding it into the centerpiece of the Hopkins Bayview Campus, home today to a completely renovated and expanded medical center, a Geriatrics Center, a biotechnology development center, the Hopkins Asthma and Allergy Center, and the clinical branches of two NIH Institutes.
He served as chairman of the Association of American Medical Colleges and its Council of Teaching Hospitals and of the Commonwealth Fund Task Force on the Future of Academic Health Centers. In addition, he was a member of the Institute of Medicine of the National Academy of Sciences; a fellow of both the American College of Physicians and the International Society of Hematology; and a member of the Association of American Physicians and the Society of Medical Administrators. In Maryland, he served on the Governor’s Commission on Black and Minority Health Care and the Baltimore City Commission on Health Care for the Homeless. He also served as professor of medicine at the Hopkins School of Medicine and as a trustee of both the Hopkins Hospital and University.
Heyssel’s strength as a leader in his field owed much to his respect for the teaching and research arms of Hopkins Medicine, and especially to the long, parallel tenure of former School of Medicine dean Richard S. Ross, M.D. “A big, imposing, man, he also was a man of his word. You always knew where he stood on an issue, and he always did what he believed strongly to be in the best interest of the Hospital,” Ross said.
Bob retired in 1992, and he and his wife (Maria) lived in Seaford, Delaware until his death in June, 2001. The Brills and Heyssels remained close friends throughout Bob;s life.
