New York Magazine contributing editor Reeves Wiedeman discusses his latest story, “The Rockefellers vs. The Company that Made Them The Rockefellers.” Wiedeman looks at how the family that pioneered the American oil industry wants to expose what Exxon hid from the public about climate change. A significant portion of the family’s wealth is still tied up in Exxon, and it's rare for an American dynasty to take on the source of its wealth. As David Kaiser, one of John D. Rockefeller’s great-great grandsons tells Wiedeman, “if Exxon’s stock price suffers, the whole family will lose money.”
