On July 16, 1960, Jane Goodall, a 26-year-old former secretary from England, began to study the behavior of chimpanzees in the wild．Until that time, scientists had mostly observed and studied chimpanzees in laboratories and zoos．Few scientists had gone to study chimpanzees in the remote areas of Africa where the chimps live．When scientists had studied the chimpanzees in the wild, they hadn’t spent long periods of time observing them．Jane Goodall planned to watch chimpanzees in Africa over a ten-year period and see exactly how they behaved．She was not a professional scientist when she started out．Her book, In the Shadow of Man, tells how she began her project and what she discovered．
As Goodall said in 1973, “I had no qualifications at all．I was just somebody with a love of animals．” Her love of animals drew her to Africa, where she met Dr Louis S．B．Leakey．Leakey was a world-famous scientist who was studying how prehistoric people lived．Since chimpanzees are humans’ closest living relatives, Leakey thought prehistoric people might have lived in the same ways that chimpanzees live today．Leakey told Goodall that studying chimpanzees might give clues about the way that early people lived．
Leakey asked Goodall to study the chimpanzees on the shores of Lake Tanganyika in Africa．The chimpanzees were very shy and the country was very difficult to travel through．Goodall took on the difficult job of finding and watching the chimpanzees．
