The Lake Carnegie Construction Photographs of the Historical Photograph Collection contains 479 dry gelatin glass plate negatives measuring 5 x 7 inches that document the construction of Lake Carnegie in Princeton, NJ. There are also 314 black and white paper prints developed at approximately the same time the glass plate negatives were made, 38 amateur photographs, and the 36 original glass plate negative boxes. The negatives and prints date from circa 1905 to 1907, with the bulk dating from 1905 to 1906. As a part of this project, funded in part by the New Jersey Historical Commission, archival contact prints (5 x 7 inches) of each negative have been created for research use and photo duplication. In addition to the glass plate negatives, original prints, and contact prints made from these negatives, there are 38 photographs taken from March through May 1905, early in the project, before any construction work had begun. These are amateur photographs, most likely taken with a Kodak Brownie camera. While many of these images are faded and soiled with fingerprints, many of the subjects are identified in writing on the border or verso of the image. There are also 7 amateur photographs and two photograph albums of unknown or uncertain provenance.
