A university career
In 1955, my father joined the faculty of New Mexico State University. He founded the school's astronomy program and went on to teach there until he retired in 1973. Here he is in about 1956, with a 12" reflector he had assembled to his specifications at the university's Physical Science Laboratory. Later, he shipped this telescope to Quito, Ecuador for use in the search for near-Earth objects—essential work for U.S. space-exploration efforts. Later still, university astronomers used the telescope under his direction for planetary research. Note the fold-away sides of the telescope enclosure.
