On Sept. 30, 2014, Dole Food chairman and owner David Murdock announced he wants to take his vision of a plant-based, healthy diet from Kannapolis to the world. On Tuesday, he said he is starting an endowment that will donate $15 million a year to the North Carolina Research Campus he founded.

The gift will continue annually “in perpetuity,” said Murdock, who, at a spry 91, said he intends to make his institute the premier research center on nutrition in the U.S.

Since then, Murdock has poured more than $800 million of his own money into building and operating the research center. According to Forbes, he is the 190th-richest American, with a net worth of about $3 billion. Murdock took Dole, the world’s largest producer of fruits and vegetables, private last year.
