The infamous inheritance battle for Koch Industries involved the four sons of Fred Koch — William, Frederick, Charles, and David — who feuded for nearly two decades over the control and ownership of the family company.
Koch Industries was founded by its namesake, Fred C. Koch, in 1940 after he developed an innovative crude oil refining process.
Fred died in 1967 and his majority interest in the company was split amongst his four sons.
In 1983, Charles and David bought out the shares of William and Frederick for $1.1 billion.
William and Frederick sued Charles and David, alleging they were cheated out of billions and that the initial buyout was undervalued. The brothers communicated only through lawyers and engaged in public efforts to discredit each other.
In 2001, the brothers reached a settlement to end the nearly 20-year-long legal battle.
The terms of the undisclosed settlement did not fully satisfy William and Frederick. Years later, Bill Koch filed a separate lawsuit against Koch Industries for alleged oil theft from federal lands.
Charles and David remained the majority owners of Koch Industries after the 2001 settlement, while William and Frederick have pursued their own ventures and interests.
