Ross Perot, the tech billionaire who upended the 1992 presidential race with an unlikely and surprisingly popular independent bid, has died, PEOPLE confirms. He was 89.

Perot had been diagnosed with leukemia, according toNBC News.

“In business and in life, Ross was a man of integrity and action,” his family said in statement. “A true American patriot and a man of rare vision, principle and deep compassion, he touched the lives of countless people through his unwavering support of the military and veterans and through his charitable endeavors.”

The family will not be speaking further and “is seeking privacy,” a spokesman said. Details of a public memorial have not bee announced.

Though he made his fortune in computers, Perot earned his largest platform with a quixotic run for president in 1992, against incumbentGeorge H. W. BushandBill Clinton.
