T. Boone Pickens, the onetime Texas oil wildcatter turned corporate raider who became a billionaire energy investor and television pitchman for wind and natural-gas power, has died. He was 91.
He died Wednesday of natural causes, according to spokesman Jay Rosser. Mr. Pickens's primary residence was in Dallas. In late 2016, he posted a message on his LinkedIn page announcing he had "several strokes" and then had a "Texas-sized fall" requiring hospital treatment. He said he was still mentally strong but in declining health, adding, "I clearly am in the fourth quarter."
In late 2017 he put his 65,000-acre Mesa Vista Ranch in the Texas Panhandle up for sale, with an asking price of $250 million. Soon afterward Mr. Pickens closed his hedge fund, writing on his website that he wanted to invest instead in "personal passions like promoting unbridled entrepreneurship and philanthropic and political endeavors."
