7. Lauren Powell Jobs (Steve Jobs)
Everyone on the planet knows that Steve Jobs was the pioneering vision behind the Apple brand until his untimely passing in 2011. He left behind his huge fortune of $19.5 billion, a $8.7 billion stake in the Walt Disney Company and 40 million shares of Apple to his loving wife Lauren Jobs. Since, she has launched the Super School Project that works to create high schools that will better meet the needs of the students of today. Steve would be so proud!
