Elder Gates was an Army veteran and founding partner of a Seattle law firm, according to his official biography.
Bill Gates said his father was instrumental in starting the charity organization that has been Gates’ central focus ever since he stepped down from running Microsoft.
“The Bill & Melinda Gates Foundation wouldn’t be what it is today without my father,” Gates said.
The family statement does not provide a cause of death, but says William Gates II was deteriorating in health.
“People were asking my dad if he was the real Bill Gates,” the tech mogul wrote. “The truth is, he was everything I try to be.”
