William Koch was born on May 3, 1940 in Wichita, Kansas to Mary Robinson and businessman Fred C. Koch. He had a twin brother named David and two older brothers named Charles and Frederick. Koch attended Culver Military Academy in Indiana, and then MIT. From MIT, Koch obtained bachelor's, master's, and doctoral degrees in chemical engineering.
Koch began his business career working in his family's company Koch Industries, in which he had inherited stock. However, after trying and failing to take over the company from his brother Charles in 1980, he was fired from the company. Koch went on to found the Oxbow Group, an energy development holding company based out of West Palm Beach, Florida. He also became president of the company. In 2011, Oxbow donated $750,000 to Restore Our Future, a Super PAC supporting the presidential campaign ofMitt Romney. The company later got into trouble for alleged tax avoidance.
William Koch is the son of Fred Chase Koch, the founder of Koch Industries, which is one of the most successful oil companies in United States history. Today Koch Industries is the second-largest private company in the US, behind Cargill, with annual revenues north of $100 billion. However, it should be noted that Bill no longer has a stake in Koch Industries after he and brotherFred Kochsold their stakes to brothersCharles KochandDavid Kochin 1983 for a combined total of $800 million. After the sale was completed, Bill became convinced that his other brothers short-changed him and/or drastically undervalued the business as a whole in order to buy him and Fred out cheaply. Bill subsequently launched a legal battle, suing for a larger payout. Fred Koch somewhat reluctantly joined the lawsuit, which dragged on for 15 years. In the end, a jury agreed that some assets were undervalued, but not in a meaningful enough way to justify any additional payout to Fred and Bill. When it was all said and done, Bill and Fred spent far more on lawyers than what they ultimately received. The lawsuit also caused a rift that severed the family to the point where when Fred would see twin brother David at charity events decades later, they would barely say hello.
