Washoe was 10 months old when her foster parents began teaching her to talk, and five months later they were already trumpeting her success. Not only had she learned words; she could also string them together, creating expressions like “water birds” when she saw a pair of swans and “open flower” to gain admittance to a garden.
Washoe was a chimpanzee.
She had been born in West Africa, probably orphaned when her mother was killed, sold to a dealer, flown to the United States for use of testing by the Air Force and adopted by R. Allen Gardner and his wife, Beatrix. She was raised as if she were a human child. She craved oatmeal with onions and pumpkin pudding.
“The object of our research was to learn how much chimps are like humans,” Professor Gardner told Nevada Today, a University of Nevada publication, in 2007. “To measure this accurately, chimps would be needed to be raised as human children, and to do that, we needed to share a common language.”
Washoe ultimately learned some 200 words, becoming what researchers said was the first nonhuman to communicate using sign language developed for the deaf.
