David Koch, the conservative billionaire who has died, was one of a pair of controversial brothers. They are commonly known as the “Koch Brothers.” He had other lesser-known siblings, though, and he also leaves behind a wife and three children.

Koch Industries wrote on its website that David Koch, the “longtime stockholder, director, and leader in Koch Industries, passed away on August 23, 2019 at age 79 after many years of fighting various illnesses.” The company described David Koch as “an all-American athlete. A chief executive officer. A U.S. vice-presidential candidate. A cancer fighter. A plane crash survivor. An extremely generous philanthropist. From a Kansan to a New Yorker. A devoted husband. A proud father.”

He was part of the pair of brothers who also earned scorn on the left for their funding of conservative political causes.

According to the Fred and Mary Koch foundation, Mary Clementine Robinson “was the daughter of a Kansas City, Missouri, surgeon who also served as a professor at the University of Kansas School of Medicine.” She later became heavily involved in the arts community.

Fred had high hopes for the younger Koch son. “David is very quick in mind and body. He is a natural athlete and very practical. If any of the kids becomes an engineer, I think it will be he,” he said, according to a Koch Industries biography.

Fred Koch, according to a Foundation bio in his name, “decided to attend Houston’s Rice Institute in 1917. He joined the Engineering Society and was elected class president his sophomore year. In 1919, he left Rice to attend the Massachusetts Institute of Technology, where he became one of the first students to obtain a degree in Chemical Engineering Practice.”

It was Fred who started the company that would grow into Koch Industries. “He moved to Wichita, Kansas, in 1925 and joined MIT classmate, P.C. Keith, at Keith-Winkler Engineering Company. The firm was later renamed Keith-Winkler-Koch Engineering Company,” the bio explains. “Following the departure of Keith in 1925, the firm became Winkler-Koch Engineering Company. In 1940, Fred Koch co-founded the Wood River Oil and Refining Co., Inc., the predecessor of Koch Industries, Inc. By 1961, the company’s name had been changed to Rock Island Oil & Refining Co., Inc., and the company was later renamed Koch Industries, Inc., in his honor.”

Mary Koch was “known to express her love of the arts through drawing and painting, Mrs. Koch was also an accomplished silversmith. She married Fred Chase Koch in 1932,” says the bio.
