Crawford H. Greenewalt (1902-1993) was an executive with the DuPont Company and president of the firm 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. Greenewalt's personal papers are primarily focused on his retirement years and his avocational interests. The papers document Greenewalt's political activities in the Republican National Committee and include exchanges with many of the leading political and business figures of the day. Of particular significance are the papers describing Greenewalt's work in photography and ornithology, beginning in 1948. These materials trace his research interests in the hummingbird and bird flight and his trips to places like Brazil, Peru, Venezuela, the Antilles, New Guinea, and the Galapagos Islands in order to observe and photograph birds in their natural habitats. Other files describe Greenewalt's work on the visiting committee at the Massachusetts Institute of Technology (1965-1987), which evaluated the school's academic programs.

Robert "Bob" Allan Olodort (1946-2019) was an inventor, industrial designer, and entrepreneur. He is best known for his invention of the "Stowaway," a portable, full-size keyboard that folds up to be pocket-size. It was used for Personal Digital Assistants (PDAs) like the Palm Pilot. Olodort invented the first computer label printer, the Smart Label Printer, among many other wireless mobile products. He holds dozens of U.S. and foreign utility and design patents. The Robert Olodort archive documents the industrial design process from both an inventor's and an entrepreneurial standpoint. The collection shows the development of a concept into a final product through product research, notes, correspondence, sketches, mechanical drawings, and prototypes. It provides valuable insight into how proprietary technology can be monetized by patenting and maintaining company relationships through development, licensing, and purchase agreements. The records also document business operations with financial files, board of directors files, and investor files. While none of the record sets are complete, there is a large enough sampling for a researcher to comprehend the complexity of design and business practices.
