Not long after the death of his father, whose heart gave out suddenly in November 1967, Charles Koch, then in his early 30s, discovered a letter his father had written when his four sons were small. "My dear boys," it began when you are 21, you will receive what now seems to be a large sum of money. It may either be a blessing or a curse." "Above all," he cautioned, "be kind and generous to one another."In the ensuing decades, Fred's legacy became a blessing and a curse. Two of his sons, Charles and David, joined forces to build Koch Industries, one of the largest private corporations in the world. But they ended up in an epic feud with brothers Bill and Frederick that spanned nearly two decades, tearing the family apart-and nearly Koch Industries along with it. Bill would start his own energy company and attain a modicum of fame as a litigious wine-collector and yachtsman (he likened winning The America's Cup in 1992 to the ecstasy of "10,000 orgasms.") After being marginalized by the patriarch because of his effete manner, Frederick became a patron of the arts and a fastidious refurbisher of historic estates.Starting with their boyhood when fraternal disputes were sometimes settled in the boxing ring, SONS OF WICHITA takes you inside this highly private family and traces the evolution of these four distinct personalities as well as their corporate, philosophical, social and political ambitions (many forget David Koch ran as the Libertarian Party's vp candidate in 1980). Influenced by the conservative, anti-communist sentiments of their father, a founding member of the John Birch Society, Charles and David devised an ambitious strategy to foist their ideological agenda upon the nation-quietly channeling millions of dollars of their fortune into a web of freemarket think tanks, academic programs, advocacy groups, and more, while also building what amounts to a shadow Republican Party, replete with a donor network capable of raising as much in an election cycle as the Republican National Committee. Never before did they flex their political muscles as vigorously as they did during the 2012 campaign, when Charles and David clashed with the Obama administration in what Charles described as the "mother of all wars."Like The Rockefellers before them, The Koch (pronounced like the soft-drink "Coke") Brothers are a great American dynasty. Unlike The Rockefellers, they have never been the subject of a major biography before.
