Named one of the most powerful women in the world by both Fortune and Forbes magazines, Safra Catz is the longest serving president and chief financial officer of Oracle Corporation. Catz immigrated to the U.S. at the age of six. After receiving her law degree from the University of Pennsylvania, she worked for a time in investment banking, rising to Senior Vice President and then Managing Director at Donaldson, Lufkin & Jenrette. Though she is known at Oracle for her low-key style, avoiding the spotlight, she was the driving force behind the company’s takeover of PeopleSoft in 2004, cementing Oracle’s position as the world’s second-largest software company. She has also served as a member of the board of directors for HSBC Holdings.
