Lucy Temerlin had a preference for gin, and would happily put on tea when her tutor came to visit. This would be perfectly normal except for the fact that Lucy was a chimp. Owned by the Institute for Primate Studies in Oklahoma and raised by Maurice Temerlin, a university professor and psychotherapist, Lucy Temerlin was a controversial experiment in blurring the lines between human and animal. Her story is documented in Temerlin's novel “Growing up Human: A Chimpanzee Daughter in a Psychotherapist's Family.” Brought up like a human, Temerlin and his wife taught Lucy to eat with silverware, sit at the dinner table, and even dress herself. To help her communicate, primatologist Roger Fouts taught her rudimentary sign language. She eventually learned more than 140 words, which she used regularly. Although she never spoke aloud, she was one of the first apes to use sign language with any air of fluency, and one of the few “speaking” animals who obviously understood what she was saying.
