In June 2018, Charles Koch told company employees that his brother would step down from the business and political empires because of health problems.

Of the two, Charles has been most involved in the political networks while David had been more active in philanthropic endeavors, mainly in NY. Their contributions to the Tea Party in 2010 were credited with giving momentum to the limited-regulation movement that arose in President Barack Obama's first term. He gave $100 million to renovate the New York State Theater in Lincoln Center, which was renamed for him in 2008. The company initially had another name - Wood River Oil and Refining Company.

Last year, David Koch stepped away from overseeing the Koch organization and other political networks due to deteriorating health. He served as a board member of the Prostate Cancer Foundation.

With the billions from their business, the Koch brothers helped to build a massive conservative network of donors for organizations that work to mobilize voters and sway elected officials in support of libertarian-leaning economic policies.

Koch was most known for co-running Koch Industries with his brother, Charles, which is the second-largest private US firm.

The family is considered the second wealthiest in the world, and there are actually four Koch brothers, but only David and Charles remained in control of the firm.

David Koch, a prostate cancer survivor, also donated hundreds of millions of dollars to medical research.

The Koch brothers did not support President Trump for election in 2016. David ran for vice president as a libertarian in 1980. The sale from one set of brothers to the other started out amicably but ultimately resulted in a 15-year legal battle in which Fred and William accused David and Charles of misrepresenting the company's fortunes and products in order to buy them out cheap.

Koch donated more than $1 billion in his lifetime. William and David are twins.

He was also, along with his older brother Charles, one of the "Koch brothers", who are regularly invoked on the left as a primary cause of all that is bad in American politics. He leaves behind his wife, Julia Koch, and three beloved children.

In addition to being a political donor, he was also a philanthropist.
