Scope and Content AGSL Digital Photo Archive - Africa presents a selection of images from the extensive photographic holdings of the American Geographical Society (AGS) Library. These images were selected from the Richard U. Light and Mary (Light) Meader Collection. This digital collection contains approximately 1080 images from Mary Upjohn Light's aerial photography in 1937-38. Mrs. Light (who later married Dr. Edwin Meader) was an adventurous aerial photographer who flew with Dr. Richard Upjohn Light, a geographer and pilot, over the continents of South America and Africa. They were the first to produce aerial photographs of these continents. Some of the first aerial photographs of the pyramids in Egypt are present in the Light/Meader Collection of negatives.
