Frank Langton "Chris" Christensen (June 1, 1910 – September 6, 2001) was an American athlete.

After receiving all-state honors at Granite High School in baseball, football, and basketball, Christensen played fullback at the University of Utah.

Originally, the company manufactured diamond drill bits for the western mining industry, but the founders quickly envisioned a strong market in petroleum.

The bits were so successful the company decided to make petroleum drilling its primary market.

Christensen also developed an erosion-resistant matrix for diamond bits and introduced the 250P-core barrel system that quickly became the industry standard.
