Includes correspondence, diaries, lab notes, photographs. Webster was a pioneering epidemiologist working at the Rockefeller Institute (1920-1943), and his collection documents this, as well as his interest in encephalitis, poliomyelitis, rabies, and resistance to infectious diseases. Other aspects of his life can be seen in his diaries and journals: diary of 1909; privately published diary of 1919, with photos, of his service in Labrador as a physician at the International Grenfell Assoc.; European journal of 1924, with photos, of Webster's honeymoon trip which was partly paid for by the Institute in order that he could meet European scientists; diary of 1929-1943; 1930 journal of a canoe trip to James Bay, with Dr. Charles C. McCoy. There is also a volume of letters concerning his death, including biographical sketches by colleagues. The contributions of his wife, Emily deForest Webster White (later married to Dr. Harold White), to Webster's work and publications can be seen in her interesting reminiscence, "Science Recollections, 1923-1971." Her own interests after Webster's death are suggested in her report of her world trip of 1964 in behalf of the Planned Parenthood Assoc. including attendance at the International Conference of Social Work, in Athens, Greece.

This collection contains correspondence, drafts of papers, the manuscript of an unpublished book, and photographs. Osterhout's interest in the electrophysiology of plants is documented, as well as his professional career at the University of California, Berkeley; Harvard University; and the Rockefeller Institute.

Eugene Opie spent most of his career as a pathologist at the Rockefeller Institute engaged in research on the influenza, tuberculosis, blood diseases, poliomyelitis, and viruses. His work at Washington University, St. Louis, is documented, as are his efforts to alleviate tuberculosis in Jamaica, among Philadelphia schoolchildren, and in New York City. The Opie collection contains correspondence, notebooks, lab notes from his days at Rockefeller, articles, reprints, and photographs. Opie's long interest in China is reflected in material on the American Bureau for Medical Aid to China, the United China Relief, and Chinese medicine in general. There is also significant documentation on the International Health Division of the Rockefeller Foundation, the Henry Phipps Institute of the University of Pennsylvania, the Milbank Memorial Fund, and other institutions. There are also reports of approximately 300 clinical autopsies performed at the Base Hospital, Camp Pike, Ark., of soldiers who died in the flu epidemic of 1918. Also there are notes of Opie's course in pathology at the University of Pennsylvania.
