The company was founded by its namesake, Fred C. Koch, in 1940 after he developed an innovative crude oil refining process. Fred C. Koch died in 1967 and his majority interest in the company was split amongst his four sons. In June 1983, after a bitter legal and boardroom battle, the stakes of Frederick R. Koch and William "Bill" Koch were bought out for $1.1 billion and Charles Koch and David Koch became majority owners in the company. Charles owns 42% of the company; trusts for the benefit of Elaine Tettemer Marshall and Elaine's children, Preston Marshall and E. Pierce Marshall Jr., own 16% of the company. The heirs of David Koch, who died on August 23, 2019, own the balance, 42%, of the corporation.
