Today that education facility is called Saint Petersburg State Pediatric Medical University.
During the war, the majority of the staff remained in Leningrad. The Germans intended to destroy the building. During the siege of Leningrad, about 400,000 children remained in the city. The Wikipedia article says:
Many of those children survived only because of self-sacrificing work of Leningrad’s pediatricians. To save lives of little citizens of Leningrad, there were created 18 baby formulas with soy, malt, and other components. Every day, the institute’s milk station fed more than 8000 babies. The main theme of research work changed and became closely related to the wartime. Distrophic conditions in children, vitamins deficiencies, war traumas were studied, described in monographies and PhD works. There were opened classes with studying of blood transfusion, the system of “the only pediatrician”, nutrition of healthy and sick children, and infectious diseases and classes of continuing education for state infection control and prevention controllers, district pediatricians, and school physicians. Two times a month, pediatricians of Leningrad visited clinical rounds. Moreover, the institute trained staff of factories for diseases control and prevention.
