The name may be a clue as to who Susan married in 1989. Her and Michael Dell, the founder of the computer company, have had four children together that all reside in Austin, Texas.

The couple have wracked up an incredible $20.8 billion fortune, but they donate quite a lot of their fortune to charity and worthy causes. The husband and wife team have even created their own foundation that aims to help struggling families, as well as children dealing with health issues.
