In reply to the discussion: Billionaire David Koch Says He’s a Social Liberal [View all]Warpy
(114,602 posts)Fred is the eldest and went to Harvard instead of MIT. His occupation is listed as "collector," although it's a bit more than that. He would seem to be the one directing the Koch Foundation, which is the arm of the family that does most of the endowments to arts and humanities.
The other three went to MIT. David and William are twins. Charles and David kicked William out of the business, getting him to "sell his shares" after a long and massive legal battle. William, however, does seem to share the political perversions of his two brothers, and donated heavily to Mitt Romney in 2012. He also had the integrity to object when he caught them siphoning oil from Indian and Federal land.
Of the two, Charles and David, it would seem that Charles is the major string puller.
