Collection of group portraits donated by Sproul Observatory. Group portraits include participants at American Astronomical Society and I.A.U. [International Astronomical Union] meetings, as well as several other taken at Johns Hopkins University, Swarthmore College, and an autographed photo of Roy W. Delaplaine at a 24-inch refractor telescope.The photographs were accumulated in the files of the Sproul Observatory, Swarthmore College, over a period of years. They form a visual record of astronomers and attendees at astronomical meetings from 1916 to 1975.
This collection contains over 37,000 35mm slides, 3,000 glass lantern slides and garden files that may include descriptive information, photocopied articles (from journals, newspapers, or books), planting lists, correspondence, brochures, landscape plans and drawings. Garden files were compiled by Garden Club of America (GCA) members for most of the gardens included in the collection. Some gardens have been photographed over the course of several decades; others only have images from a single point in time. In addition to images of American gardens, there are glass lantern slides of the New York Flower Show (1941-1951) and trips that GCA members took to other countries, including Mexico (1937), Italy, Spain, Japan (1935), France (1936), England (1929), and Scotland. A number of the slides are copies of historic images from outside repositories including horticultural and historical societies or from horticultural books and publications. The GCA made a concerted effort in the mid-1980s to acquire these images in order to increase its documentation of American garden history. Because of copyright considerations, use of these particular images may be restricted.
