===Hale Telescope===
{{Main|Hale Telescope}}

The 200-inch telescope is named after astronomer and telescope builder [[George Hale|George Ellery Hale]]. It was built by Caltech with a $6&nbsp;million grant from the Rockefeller Foundation, using a [[Pyrex]] blank manufactured by [[Corning Glass Works]] under the direction of George McCauley.  [[John August Anderson|Dr. J.A. Anderson]] was the initial project manager, assigned in the early 1930s.<ref>{{cite magazine|magazine=Popular Mechanics|author=Hearst Magazines|title=Super Camera of the Skies|url=https://books.google.com/books?id=TtcDAAAAMBAJ&pg=PA52|date=April 1942|publisher=Hearst Magazines|page=52}}</ref> The telescope (the largest in the world at that time) saw [[First light (astronomy)|first light]] January 26, 1949, targeting [[NGC 2261]].<ref>[http://365daysofastronomy.org/2009/01/26/january-26-60th-anniversary-of-hale-telescope-first-light/ "60th Anniversary of Hale Telescope,"] ''[[365 Days of Astronomy]]'' (podcast).

The 200-inch telescope was the largest telescope in the world from 1949 until 1975, when the Russian [[BTA-6]] telescope saw [[first light (astronomy)|first light]]. Astronomers using the Hale Telescope have discovered [[quasar]]s (a subset of what was to become known as [[Active Galactic Nuclei]]) at [[expansion of the universe|cosmological]] distances. They have studied the chemistry of stellar populations, leading to an understanding of the [[stellar nucleosynthesis]] as to origin of elements in the universe in their observed abundances, and have discovered thousands of [[asteroid]]s. A one-tenth-scale engineering model of the telescope at [[Corning Community College]] in [[Corning (city), New York|Corning, New York]], home of the Corning Glass Works (now Corning Incorporated), was used to discover at least one minor planet, [[34419 Corning]].{{JPL|34419|†}}
