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.
