You all know the story: Lowly intern at massively wealthy company moves up the ladder to become CEO of said company. Or perhaps you don't know the story because it never really happens, minus a few dream sequences in movies. But Ursula Burns — CEO of a little outfit called Xerox — did just that, and became the first African American CEO of a Fortune 500 company to boot.
Burns joined Xerox fresh out of Columbia University, where she received her master's degree in mechanical engineering.

In 2009, she was named CEO – nearly 30 years after the world's most successful summer internship [source: Iqbal].
