3. Patricia Woertz
Chairman, president and CEO
Archer Daniels Midland (ADM)
2009 rank: 3
Age: 57

She built her career in big oil, but now oversees 240 plants that turn agricultural sources into food and chemicals. ADM is already the world's largest corn processor; now Woertz is focused on other fuel and energy sources. Investors clearly like the push: ADM stock has climbed 13% in the past 12 months.
