California State Polytechnic University, Pomona, or Cal Poly Pomona, is a public university located in Pomona, California, United States. It is one of two polytechnics in the 23-member California State University system. Cal Poly Pomona began as a satellite campus of the California Polytechnic School (today known as Cal Poly San Luis Obispo) in 1938 when a completely equipped school and farm in the city of San Dimas were donated by Charles Voorhis and his son Jerry Voorhis. The satellite campus grew further in 1949 when a horse ranch in the neighboring city of Pomona, which had belonged to Will Keith Kellogg, was acquired. Cal Poly Pomona, then known as “Cal Poly Kellogg-Voorhis”, and Cal Poly San Luis Obispo continued operations under a unified administrative control until they became independent from each other in 1966. Cal Poly Pomona currently offers multiple educational programs in 9 academic units and enrolls over 22,000 students as of fall 2010. The university is one among a small group of polytechnic universities in the United States which tend to be primarily devoted to the instruction of technical arts and applied sciences.
