He attended Bethel Mennonite Church in Wadsworth and excelled academically at Wadsworth High School. He graduated magna cum laude from Case Institute of Technology, Cleveland, Ohio, with a bachelor’s degree in mechanical engineering. He pursued graduate work at the University of Colorado, Boulder, where he completed master’s (in 1968) and doctorate (in 1973) degrees in mechanical and chemical engineering, respectively. His love of the great American West kept him based in Boulder for the rest of his life.

He taught at UC Boulder from 1976 until retiring in 1996 as professor emeritus. He was founding director of the Joint Center for Energy Management in the Department of Civil, Environmental and Architectural Engineering at UC Boulder from 1986 to 1996, and the recipient of numerous awards.

In 1992, he and his wife spent six months in Paris while he was a guest professor at the École de Mines, followed by six months on the Lago Maggiore as visiting professor at the Joint Research Center in Italy.

The time in Italy confirmed him as an Italophile. He carried his love of Italian cars, wine and food throughout his life. After retirement, he continued consulting work on alternative energy sources for companies like Toyota. He donated expertise to projects with the World Wildlife Fund and the government of Ecuador to preserve the ecosystem of the Galapagos Islands.

He hiked, biked, skied, climbed and drove at top speed throughout the West, always pursuing the best. He spent hours restoring, driving and modifying cars, often including his grandchildren in this and their school science projects.

Survivors include his wife, Dorothy (Dottie) Lang Kreider; her daughter, Valerie (Gary) Mesch; a brother, Gerald (Karen) Kreider; and five grandchildren.
