A pathologist and researcher at the Rockefeller Institute of Medical Research, 1914-1922, Harold Lindsay Amoss (1886-1956) specialized in research on infectious diseases ranging from poliomyelitis to meningitis, erysipelas, brucellosis, and encephalitis. The Amoss Papers are comprised primarily of materials relating to Harold Amoss' medical service in the United States Army during the First World War (1918-1919), to his research at the Rockefeller Institute of Medical Research, 1920-1922, and to his efforts to develop vaccines for meningitis and poliomyelitis.

Victor George Heiser, who was a preeminent public health physician, created a rich archive of material documenting all phases of his career, especially the international health work of the Rockefeller Foundation from 1915-1934. There are voluminous, detailed, and interesting diaries for the whole course of his adult life (1890-1972). There are notebooks reflecting on his early training and work (1890-1907), and lectures he attended at Jefferson Medical College in Philadelphia (1897).
