Jane Goodall may be one of the most famous field researchers in history.
Her studies of chimpanzees in Tanzania under archeologist S.B. Leakey began in 1960, when she was only 26 years old, and made her one of the most respected -- and beloved -- faces in conservation. Among her discoveries: that chimpanzees ate meat, had the intelligence to make and use tools, and lived in small groups instead of large troops.
Today, her eponymous Jane Goodall Institute focuses its efforts on saving endangered chimpanzees, especially those in the Gombe National Park in Tanzaniza, while her Roots & Shoots program offers opportunities to get involved with environmental and humanitarian efforts to more than 150,000 school-aged children in 120 countries.
