Nim Chimpsky (November 19, 1973 – March 10, 2000) was a chimpanzee who was the subject of an extended study of animal language acquisition (codenamed 6.001) at Columbia University, led by Herbert S. Terrace. Chimpsky was given his name as a pun on Noam Chomsky, the foremost theorist of human language structure and generative grammar at the time, who held that humans were "wired" to develop language.
The validity of the study is disputed, as Terrace argued that all ape-language studies, including Project Nim, were based on misinformation from the chimps. R. Allen and Beatrix Gardner made a similar earlier study, called Project Washoe, in which another chimpanzee was raised like a human child. Washoe was given affection and participated in everyday social activity with her adoptive family. Her ability to communicate was far more developed than Nim's. Washoe lived 24 hours a day with her human family from birth; Nim at 2 weeks old was raised by a family in a home environment by human surrogate parents to see if he could refute Noam Chomsky's thesis that language is inherent only in humans. Both chimps could use fragments of American Sign Language to make themselves understood.
