T. Boone Pickens died Wednesday in his Dallas-area home at the age of 91 of natural causes, his foundation confirmed.
The self-described “opinionated energy investor, entrepreneur, proponent of American energy resources, and philanthropist” made billions in oil and gas ― both in its extraction, and in managing a hedge fund focused on the commodity.
Pickens spent the proceeds freely on causes he deemed important. In 2010, the “Oracle of Oil” pushed heavily for rapid, nationwide adoption of wind, solar and other green energy sources as part of his 10-year “Pickens Plan.”
Pickens’ health began deteriorating in 2016 after he suffered a series of strokes. After he sustained a head injury in a fall in 2017, Pickens retired entirely in 2018.
