This collection includes letters, a diary, photographs, printed matter, souvenirs, etc. of the international geographical trip of the American Geographical Society of New York to the west coast. Included are circulars and bulletins printed and issued along the way.

This collection contains personal and professional correspondence, data on Smith's studies on plant pathology, photographs of diseased plants, and some genealogical data.

This collection includes letters, diaries, notebooks, and early photographs, relating primarily to the Wister family of Germantown and Philadelphia. Much of the correspondence concerns domestic news and consists of letters from or to Sarah Wister. These include interesting observations on Germantown and Philadelphia society from other families as well, such as the Bayntons and Bullocks. There are numerous letters from various Wisters, including Casper, Charles Jones, Elizabeth (including a journal of a trip to Bristol, 1783), Hannah, John, Owen Jones, and others. There is also poetry by Sarah.

A collection of letters (family and professional), notebooks, diaries, lectures, articles, and photographs, of Smith, a noted American geographer who influenced the teaching of geography after 1920 through his many elementary texts. There is much material relating to these writings. His contributions to the rise of human geography and the related areas of conservation and ecology, are documented. His study in Europe under Friedrich Ratzel, at Leipzig in 1901-1912, is touched on in his journal for those years; included are many interesting observations on German university life. There is also much material on his nursery business in Virginia. Organizational files are numerous, e.g. Association of American Geographers, Columbia University, U. S. Department of Agriculture. Much of the correspondence is limited to only a few letters from each correspondent. Among the names included are: Willard G. Bixby, Isaiah Bowman, John W. Hershey, Emory R. Johnson, Walter C. Lowdermilk (of particular note is his 1926 paper, written while at the University of Nanking, "Forest Conservation in Shansi, China"), and Lewis Mumford.

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.

William Jacob Robbins (1890-1978, APS 1941) was a botanist and physiologist. From 1937 to 1957 he was director of the New York Botanical Garden. His research focused on culture methods of plants in relation to biochemistry and nutrition, especially on the synthetic abilities of fungi. His studies paralleled the scientific agenda of the Rockefeller Foundation, an agency with which he was closely associated for years as adviser and trustee. He was perhaps the most influential botanist in the National Academy of Sciences (NAS) during the early postwar era, and a principal participant in the plans for the global reconstruction of science. Robbins served as president of the American Philosophical Society from 1956 to 1959.

Robert Cushman Murphy (1887-1973), one of the twentieth century's great ornithologists, was curator of mammals and birds at the Brooklyn Museum (1911-1917) and was curator of birds and later chairman of birds at the American Museum of Natural History (1917-1973). The world's foremost authority on sea birds, in 1936, he penned Oceanic Birds of South America, a two volume set. An ardent traveler and explorer, he kept copious notes of his travels, which he typed up, illustrated and had bound. The APS library owns forty-two bound journals. Murphy was made an APS member in 1946. A pioneer in the study of the ecology, a louse, fish, plant, lizard, an Antarctic inlet, spider, and two mountains have acquired his name. This collection contains diaries, journals, articles, addresses and observations of Murph;, generously illustrated with newspaper clippings, photographs, letters, sketches, maps, and charts.
