Jane Goodall

I hate to come on here with what could very well be childhood delusions, but I am almost certain that Jane Goodall worked with mostly gorillas. I was almost certain that she worked in the Congo with western lowland gorillas, but recently after talking with my brother about it he said she worked with chimpanzees. Is it just the fact that so many people got it wrong over the years that it has almost everyone believing that she worked with gorillas? Please some one help me out here.
