U.S. billionaire businessman and one of the richest men in the world, David Koch has died at the age of 79. He died at his Manhattan home.
Late Koch was a philanthropist, political activist, and chemical engineer. He joined the family business Koch Industries, the second-largest privately held company in the United States, in 1970. Wikipedia
David Koch and his brother, Charles, co-owned Koch Industries, a Nebraska-based energy and chemical company. He stepped down from running the Koch organization last year due to declining health.
The Koch brothers helped reshaped American politics. They built a massive conservative network of donors for organizations that work to mobilize voters and sway elected officials in support of libertarian-leaning economic policies.
His brother, Charles G. Koch confirmed the death in a statement in which he disclosed that David Koch had been treated for prostate cancer in the past.
“Twenty-seven years ago, David was diagnosed with advanced prostate cancer and given a grim prognosis of a few years to live. David liked to say that a combination of brilliant doctors, state of the art medications and his own stubbornness kept the cancer at bay,” the statement said.
