Harold P. Cahoon was born in Salt Lake City. After graduating from Granite High School he attended the University of Utah and obtained the first B.S. degree in Ceramic Engineering and Mineralogy. Upon receiving the Edward Orton Fellowship at the University of Washington, Cahoon earned an M.S. degree in Ceramic Engineering with a minor in Mineralogy. Cahoon returned to the University of Utah to receive a Ph.D. in Ceramics with a minor in Mineralogy in 1955.

Harold is the grandson of John P. Cahoon, who founded Interstate Brick Company in 1891. Harold's father, John B. Cahoon, served as president from 1960 until his death on 1 April 1966, whereupon Harold took over the company. Harold had been employed by Interstate Brick for 32 years before he became president. He expanded the company in the late 1960s, making the company diversify into tile and arranging with Mountain Fuel Supply for a merger with Entrada Industries. Because the merger provided the capital the company needed for expansion, the newly-formed Interstate Brick Division of Entrada Industries was able to build a larger plant in 1972 to meet demand. Interstate Brick was able to expand its sales with the new plant. The collection includes a variety of pamphlets and newspaper articles about Interstate Brick Company, both before and during Harold's leadership.

Cahoon has worked in other corporate leadership positions in Entrada Corporation, Wasatch Chemical Company, Fox Clay Company, and Interstate Land Company.

Interstate Brick Company continues to function as a major corporation in Utah, having joined with Pacific Coast Building Products in 1990.

Harold and his wife Priscilla Johnson Cahoon founded the Washington City Historical Society in 1992. They co-authored the book Utah's "Dixie" Birthplace (Washington City, Utah: Washington City Historical Society, 1996).
