 On 13 March 1956, Senators Lister Hill and John F. Kennedy submitted Bill S.3430 to Congress, which promoted "the progress of medicine and advanced national health and welfare by creating the National Library of Medicine".On 3 August 1956 President Dwight D. Eisenhower signed the legislation which transformed the “Armed Forces Medical Library” into the "National Library of Medicine".The Library collection was thus transferred from the control of the United States Department of Defense to that of the PHS of the Department of Health, Education and Welfare.
