My Land, My Heritage, My Hope: Slide 82
title My Land, My Heritage, My Hope: Slide 82description Photograph of two domed buildings on a mountaintop; they contain telescopes that are part of the McDonald Observatory. The image accompanied a written speech, with the caption: "The McDonald Observatory was constructed on Mt. Locke in the Davis Mountains in the 1930's with money given to the University of Texas by William Johnson McDonald. The site was chosen because of its high percentage of clear nights and its isolation from brightly lighted cities. The observatory is sixty-eight hundred feet above sea level, and until 1948, the 82-inch lens was the larges in the world. In 1968, a new 107-inch lens was installed in a new building adjacent to the original plant" (pp. 9-10).artist/creator Unknownsubject Planetariums Mcdonald Observatory Davis Mountains Observatories Astronomy Architecture - Buildings Telescopes Science And Technologycontributor Portal to Texas History (TPTH)
