During World War II, many hospital physicians and researchers were called to military service. Working at the Research Foundation, Samuel Rapoport developed a way to preserve whole blood, a breakthrough that helped save lives on the battlefield. His research colleague, Albert Sabin, served in the US Army Medical Corps and did important research on encephalitis, sandfly fever and dengue fever. At the war’s end, Sabin returned to Cincinnati Children’s to continue his pioneering research on polio.
After the war, Ashley Weech, MD, chairman of the Department of Pediatrics and director of the Children’s Hospital Research Foundation, began to rebuild the hospital staff. New pediatric subspecialty departments were established, and a new research and laboratory wing was added in 1950.
