Abstract:: The Division of Environmental Research (DER) was established as a department of the Academy of Natural Sciences in 1947 by botanist and limnologist, Dr. Ruth Patrick. Originally called the Department of Limnology, the department was envisioned by Patrick as a multidisciplinary team of scientists devoted to helping protect the quality of the environment. Not only was environmental research a novel idea for the time, but the multidisciplinary nature of the research was also innovative. The primary goals of the Division were to, "understand aquatic and terrestrial ecosystems, including the effects of natural processes and human activities; apply this knowledge to assess ecosystems health and developing watershed-level strategies for enhancing environmental quality; and work with diverse stakeholders, including government, community groups, industry and environmental organizations to improve environmental stewardship" (ansp.org). This collection provides evidence of the activities of...(see more)

Abstract:: Born in Topeka, Kansas, in 1907, Dr. Ruth Myrtle Patrick spent most of her childhood in Kansas City, Missouri. Her interest in the natural sciences was shaped by her father's passion for the natural world. Her long association with the Academy of Natural Sciences began in 1933 as a volunteer. By 1937 she was curator of the Academy's Leidy Microscopical Collection and involved in the consolidation and expansion of the Academy’s diatom herbarium, but not on the Academy payroll until the early 1940s. From 1973 to 1976 she was the first woman to chair the Academy of Natural Sciences' Board of Trustees and later held the Academy’s Francis Boyer Chair of Limnology. She formed the Environmental Associates, a group of corporate executives concerned about environmental effects of industrial activities. She taught limnology and botany at the University of Pennsylvania for more than 35 years and wrote more than 200 scientific papers and a number of books. In 1970, Patrick became...(see more)

Abstract:: Crawford Hallock Greenewalt (1902-1993) was a chemical engineer and the President of the DuPont Company from 1948 to 1962. He had a passion for the natural sciences, and combined his love of ornithology with photography. He was especially known for his high speed photographs of hummingbirds. His ornithological interests included bird songs, the radiance of hummingbird feathers and the evolution of shapes and sizes of birds in relation to their flight abilities. The Crawford H. Greenewalt papers document Greenewalt's personal study of ornithology, primarily his work on hummingbirds. The collection dates from 1951 to 1993 and consists primarily of photographs taken by Greenewalt, and technical data collected by Greenewalt. The images photographed by Greenewalt exist in many different formats throughout the collection, including prints, negatives, and slides. The technical data in this collection represents Greenewalt's research into the physiology of hummingbirds, and the development...(see more)

Abstract:: Horace G. Richards (1906-1984) was a geologist at the Academy of Natural Sciences, Philadelphia and an authority on the geologic formations of the Atlantic coastal plain. His research specialty focused on geology and paleontology of the Quaternary Period (approximately the past 1.8 million years), but his research interests also included Cenozoic mollusca, and marine Pleistocene geology and paleontology of the Atlantic coastal plain. Additionally, he studied climate change and coastal shorelines, which required extensive fieldwork, taking him all over the world. Richards was also an adjunct professor at two universities and frequently guest lectured at various institutions. The Horace G. Richards papers document various aspects of his professional career, from his graduate education at the University of Pennsylvania to his retirement from the multiple positions he held. Materials in this collection include: general business correspondence; photographs and slides from his field work...(see more)
