Nelson Bunker Hunt, 88, a Texas oilman who once tried to corner the silver market with one of his brothers only to see the move end in financial disaster, died Tuesday at a Dallas assisted-living center after a long battle with Alzheimer's disease, his brother, W. Herbert Hunt, said.

Mr. Hunt was among the world's wealthiest men. His father was legendary Texas oilman H.L. Hunt, who left behind a multibillion-dollar fortune and Placid Oil Co., once one of the biggest independent oil companies.

Nelson Bunker Hunt built on his father's oil and gas holdings, finding a rich Libyan oil field only to have it nationalized later by Moammar Gadhafi. He owned millions of acres of farm and ranch land in Australia, race horses, and an ancient coin collection.

But a huge, soured bet on the silver market by Mr. Hunt and his brother, Herbert, led to legal problems and bankruptcy. The brothers lost more than $1 billion in March 1980 when the price of silver collapsed. - AP
