Cheyenne, Wy – Conservationist and philanthropist Laurance Rockefeller, who helped national parks in Wyoming, has died. He was 94.
Rockefeller was number 377 on this year's Forbes magazine list of 587 billionaires, with 1-point-5 billion dollars.
But he was perhaps best known for his work in the field of conservation and his affinity for the environment.
In 1958 he founded the American Conservation Association to advance public knowledge of the field.
He also was head of Jackson Hole Preserve, a conservation organization that played a major role in protecting parts of the Grand Tetons and redwood trees in California.
Rockefeller also donated a ranch in Wyoming to Grand Teton National Park.
Rockefeller died in New York.
