MARTHA STEWART—EST. $638 MILLION

Martha Stewart is clearly someone that deserves credit for being able to turn things around. And, boy, was she able to turn things around. She was incarcerated for 5 months for committing securities fraud, but was able to make a comeback right after—she returned to television, released a book, and launched a line of products under her brand.

After 30 years of hard work, Martha has become one of the most famous women in the business world in the United States. The household products enterprise named after her name, which she founded from scratch, is very famous in the United States.  It’s pretty amazing what she was able to do just after what must have only been the worst few months of her life. With Martha’s rare mindset and work ethic, it’s no wonder she’s worth $638 million.
