OKLAHOMA CITY (AP) - T. Boone Pickens, who amassed a fortune as an oil tycoon and corporate raider and gave much of it away as a philanthropist, has died. He was 91.

Spokesman Jay Rosser confirmed Pickens' death Wednesday to The Associated Press.

Pickens made his first millions in oil, burnishing an image as a maverick, unafraid to take on giants in the oil patch. Even his name seemed to fit, like central casting's idea of what an oilman should be named.

Starting in the 1980s, he became known for launching hostile corporate takeover bids that often resulted in a huge payoff. His fortune soared into the billions.

Pickens flirted with the idea of marketing water from West Texas to the state's metropolitan areas. In a break from his past, he also developed wind farms.

Gov. Greg Abbott released  the following statement on Boone's passing: 

“Although born in Oklahoma, Texas has always considered T. Boone Pickens to be one of our own. He was a passionate man who always stood by his principles on his path to success. T. Boone Pickens’ commitment to establishing American energy independence will have a lasting impact on the state of Texas, and the United States of America. Throughout his life and career, he generously gave to charitable causes to advance education, medical research, and humanitarian needs. I ask that all Texans join Cecilia and me in remembering the legacy of T. Boone Pickens, and keep him and his family in their prayers.”
