Oracle Founder and Chairman Larry Ellison confirmed Hurd's death Friday.
In 2010, Oracle boss Ellison slammed HP for letting go of Hurd "Steve Jobs many years ago.", calling it "The worst person's decision since the idiots on the Apple board." He then hired Hurd on as president, sharing the position with Safra Catz.
Oracle is one of HP's chief rivals, and the company has a long history of litigation and nastiness. Hurd's appointment ruffled some feathers in Silicon Valley.
Hurd to joining: It sued Oracle in an attempt to stop Hurd from joining. In court documents filed in 2010, HP said it believed Hurd had put "most valuable trade secrets and confidential information in peril."
But Oracle needed an experienced salesman as Amazon ( Microsoft and Google began to grow their cloud computing businesses. That left Oracle's middleware and database products outlook. )
Since Hurd's arrival, the company has greatly expanded its cloud computing portfolio, although Oracle still trails its competitors by a wide margin. He was born in New York City, 1957, on the Upper East Side, according to his personal website.
The tech boss started his career in 1980 at ATM company NCR as a junior salesman. He became his CEO in 2003. He became HP's CEO in 2005, replacing ousted CEO Carly Fiorina. Following his jump to Oracle in 2010, he was then promoted to CEO in 2014. He oversaw how Oracle would sell and market products, while Catz handled finance, legal and operations.
Hurd was married to his wife, Paula, for nearly three decades. Paula had worked alongside him at NCR, where she had been a senior executive. They had two daughters and lived in the Bay Area.
Correction: Hurd's age misstated an earlier version of this story.
