Company: DuPont
Fortune 500 rank: 72

DuPont CEO Kullman has added sparkle to the chemical giant over the past three years - and has managed to keep her home life intact. She gives credit to her husband (who also works at DuPont) and University of Delaware students as babysitters, and Kullman acknowledges she's still learning both professionally and personally.

"What I do is a labor of love, right? And you don't always get it right. You know, as a parent you don't always get it right, but you learn," she told Fortune assistant managing editor Leigh Gallagher at the 2011 Fortune Most Powerful Women Summit. "And I'm a big believer that people and organizations -- if they keep learning, they'll figure it out. If we stop learning, we stop growing."
