From a young age, it was my dream to go to Africa and work with animals. Everybody laughed at me, but my mother, Vanne, told me never to give up, and that I could always find a way.

So, when I was 23, after saving up my earnings from working as a waitress, I went to wild, untamed (野性的) Africa and began my work. In 1960 I went to the Gombe Stream Chimpanzee Reserve. At that time, we knew nothing of the behavior or social structure of chimps (黑猩猩), and I was to go there and see what I could find out. Usually, when you wake up, you leave your dreams behind you, but I found myself waking up to my dream.

As the British government wouldn’t let me go without older women’s company, my amazing mother came with me and stayed for four months. We shared a second-hand army tent, and we used the stream for fresh water and washing. We could swim in the lake, although there were crocodiles.

It was beautiful there, although both my mother and I nearly died of malaria (疟疾). I was scared I wouldn’t be able to do what I had set out to, because, at first, the chimps ran away from me in fear. I spent my days watching, listening, tracking and in the evenings writing up my notes.

For my mother, who stayed back at the camp, it must have been terrifying, and very lonely. There were snakes and spiders, as well as an old leopard who would come by. But she had an amazing way with people, and would hand out medicines to the fishermen, who saw her as a witch doctor.

In my fifth month there, I finally saw one of the chimps, which I called David Greybeard, stripping (剥光) straw to “fish” for termites (白蚁). It proved that man wasn’t the only toolmaker, and that everything had to be redefined.
