While serving in the United States Army as a first lieutenant during World War II and stationed at a military hospital in England, Ginsberg was responsible for caring for soldiers injured during the Normandy landings. There he discovered a pattern of hepatitis infections in those individuals who had received blood transfusions. Further investigation showed that the patients had contracted Hepatitis B from pooled plasma, which led to changes in transfusion practices and resulted in a significant reduction in illness and death among soldiers being treated.[3] In recognition of these efforts, he was awarded the Legion of Merit in 1945.[1]
After completing his military service, he was an associate at the Rockefeller Institute in New York City starting in 1946. He was on the faculty of Western Reserve University starting in 1951, where research he conducted showed that adenoviruses, which could lie dormant in the adenoids for extended periods, were among the causes of atypical pneumonia and acute respiratory disease. Ginsberg showed the process by which the adenovirus caused disease after entering host cells, leading to the creation of vaccines against various infectious diseases and showing how cancers could be triggered by oncoviruses.[3]
A widely published author of more than 200 scientific papers and a standard text on microbiology, Ginsberg was inducted as a member of the National Academy of Sciences. Dr. Saul J. Silverstein of the Columbia University College of Physicians and Surgeons called Ginsberg "a giant in this field" whose "discoveries involving the genetics of adenoviruses paved the way for the development of gene therapy". Dr. Robert M. Chanock, who headed the Laboratory of Infectious Diseases at the NIAID, noted that "he had accomplished all he could with adenoviruses" before moving on to study HIV.[3]
A resident of both Woods Hole, Massachusetts and Washington, D.C., Ginsberg died at age 85 on February 2, 2003 in Woods Hole due to pneumonia. He was survived by his wife, the former Marion Reibstein Ginsberg, as well as by two daughters, two sons and eight grandchildren.
