Martha Stewart -- Martha Stewart Living
She is the business mind and "homemaking" skill behind Martha Stewart Living. After her divorce in 1989, having gained experience running a home-based catering business and converting a Connecticut farmhouse into her family's home and a picture of rustic refinement, she turned her skills into an empire.
There were books, a magazine, a TV show -- and finally a "homemaking" media conglomerate that positions her as not only the foremost expert on beautiful living but also one of the wealthiest and most influential women in America.
Up next: Even in the world of self-made women, she's a jaw-dropper.
