San Francisco: Oracle co-chief executive Mark Hurd died on Friday, about a month after taking a medical leave of absence from his post, the US technology company said.
Hurd, 62, took a break from his positon at Oracle in September, saying in a release that he "needed more time to take care of my health".
Since Hurd and Safra Catz began running the California-based cloud computing company together in September of 2014, Oracle shares rose more than 30 per cent.
Hurd joined Oracle in 2010.
Hurd previously been chief of computer maker Hewlett-Packard, where he worked from 2005 until 2010 when he was forced to resign as a result of allegations of sexual harassment by a former subcontractor of the group.
Hurd's work career included 15 years at NCR, maker of cash register and teller machines, where he served a stint as chief executive.
"It is with a profound sense of sadness and loss that I tell everyone here at Oracle that Mark Hurd passed away early this morning," Oracle co-founder and chairman Larry Ellison said in an email to employees posted online by CNBC.
"All of us will miss Mark's keen mind and rare ability to analyze, simplify, and solve problems quickly. Some of us will miss his friendship and mentorship."
