Raymond Pearl spent the majority of his academic career (1918-1940) at Johns Hopkins University, where he was Professor of Biometry and Vital Statistics and Director of the Institute of Biological Research. Founder of the Quarterly Review of Biology and Human Biology, he made significant contributions in the areas of biology, genetics, eugenics, and statistics. The Pearl Papers includes correspondence as well as notebooks, scrapbooks, diplomas, photographs, and 33 volumes of diaries. There is significant correspondence with his wife, Maud (ca. 500 letters), and mother, Ida May (ca. 300 letters), particularly for the years 1895-1934. Of special note is Pearl's correspondence with his friend, colleague, and fellow Baltimoreian, H. L. Mencken (ca. 500 letters). The collection contains important information on the American Association of Physical Anthropologists, The Baltimore Sun, the Birth Control Federation of America, Dartmouth College, the International Institute of Statistics, Johns Hopkins University, and the National Academy of Sciences. This note is currently under review for revision.

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.
