Lantern Slides

A collection of mounted images most probably used to illustrate lectures and to disseminate news. The slides are a mix of original material from Boyden Observatory and commercially-available reproductions. The bulk of the material consists of reproductions of plates taken at Boyden Observatory (South Africa) showing the progress of site construction, serving as a valuable record of early development. A few images show widely-reproduced views of Boyden Observatory while in Peru. A small number of slides appear to be reproductions that were commercially available in the 1910s, showing famous telescopes and buildings in the United States of America, Canada, and Germany. Several slides depict celestial objects. n/a. Extent: 105 lantern slides, glass positives with black paper masks and taped edges.
