Reports are emerging that the Rockefeller Family Fund is divesting from the oil industry upon which the Rockefeller family fortune was built (archived). Late family patriarch John D. Rockefeller built the fortune his descendants enjoy with his energy start up Standard Oil, a firm Rockefeller grew though unprecedented horizontal and vertical integration from its inception in 1870 until it was slain by US regulators in 1911. The Rockefeller Family Fund singled out ExxonMobil, the largest direct descendant of their late patriarch's Standard Oil for criticism. An ExxonMobil spokesperson responded alleging a conspiracy by the family against them. It is unknown whether Rockefeller's human and corporate descendants have sought counselling or mediation in the past for their issues. Meanwhile despite some upward movement in oil prices from the level they began the year at prospects for the energy industry as a whole remain bleak.
