Diane von Furstenberg & Barry Diller – $6.65 Billion

Today, Diane von Furstenberg is the proud owner of her very own eponymous fashion company, which is available in 70 countries. Even so, like many of the world’s big-name figures, Diane began her journey at square one. Her introduction to the fashion designing business was when she worked at a textile factory, where she also learned about cut, color, and fabric. Soon after, she began making her own dresses, one of which is the now-iconic fashion piece, the “wrap dress.”

In 2001, Diane married Barry Diller, a businessman who founded the Fox Broadcasting Company. Along the way, Barry has worked for companies like Paramount Pictures, Fox, and USA Broadcasting. With that said, he has also taken credit for being the mentor of many of the industry’s high-ranking executives, including Uber’s CEO Dara Khosrowshashi, Columbia Pictures’ president Dawn Steel, and BBC America’s president Garth Ancier.
