The Kitt Peak National Observatory of the United States was dedicated on March 16, 1960.
At the dedication a 36-inch telescope and various facilities were ready.
Construction was underway for the then planned 84 inch telescope. (
i.e the KNPO 2.1 meter)
The 84 inch (2.1 m) had its first light in September 1964.

Over the decades the mountaintop hosted many telescopes, and achieved a variety of discoveries.
Some examples of astronomical research KNPO contributed to include the study of "Dark Matter", Cosmic distances, high-redshift galaxies, and the bootes void.
In addition, the observatory has engaged in variety of public outreach and education programs.

In 2018, KNPO established plans for its Windows on the universe Center for Astronomy Outreach.
