Nim Chimpsky: The Chimp Who Would Be Human

Now Elizabeth Hess’s unforgettable biography is the inspiration for Project Nim, a riveting new documentary directed by James Marsh and produced by Simon Chinn, the Oscar-winning team known for Man on Wire. Hess, a consultant on the film, says, “Getting a call from James Marsh and Simon Chinn is an author’s dream. Project Nim is nothing short of amazing.”

An adorable baby chimp, a loving family, and an experiment that changed the lives of all it touched . . .

Project Nim, the brainchild of a Columbia University psychologist, was designed to refute Noam Chomsky’s claim that language is an exclusively human trait. Nim Chimpsky, the chimpanzee chosen to realize this potentially groundbreaking experiment, was raised like a human child and taught American Sign Language while living with his “adoptive family” in their elegant Manhattan town house. But when funding for the study ended, Nim’s problems began. Over the next two decades he was exiled from the people he loved, put in a cage, and moved from one facility to another, including, most ominously, a medical research lab. But wherever he went, Nim’s humanlike qualities and his ability to communicate with humans saved him. A creature of extraordinary charm and charisma, Nim ultimately triumphed over a dramatic series of reversals and obstacles. His story, both moving and entertaining, also raises the most profound questions of what it means to be human—and about what we owe to the animals who enrich our lives.

Could an adorable chimpanzee raised from infancy by a human family bridge the gap between species—and change the way we think about the boundaries between the animal and human worlds? Here is the strange and moving account of an experiment intended to answer just those questions, and the astonishing biography of the chimp who was chosen to see it through.

Dubbed Project Nim, the experiment was the brainchild of Herbert S. Terrace, a psychologist at Columbia University. His goal was to teach a chimpanzee American Sign Language in order to refute Noam Chomsky’s assertion that language is an exclusively human trait. Nim Chimpsky, the baby chimp at the center of this ambitious, potentially groundbreaking study, was “adopted” by one of Dr. Terrace’s graduate students and brought home to live with her and her large family in their elegant brownstone on the Upper West Side of Manhattan.

At first Nim’s progress in learning ASL and adapting to his new environment exceeded all expectations. His charm, mischievous sense of humor, and keen, sometimes shrewdly manipulative understanding of human nature endeared him to everyone he met, and even led to guest appearances on Sesame Street, where he was meant to model good behavior for toddlers. But no one had thought through the long-term consequences of raising a chimp in the human world, and when funding for the study ran out, Nim’s problems began.

Over the next two decades, exiled from the people he loved, Nim was rotated in and out of various facilities. It would be a long time before this chimp who had been brought up to identify with his human caretakers had anotheropportunity to blow out the candles on a cake celebrating his birthday. No matter where he was sent, however, Nim’s hard-earned ability to converse with humans would prove to be his salvation, protecting him from the fate of many of his peers.

Drawing on interviews with the people who lived with Nim, diapered him, dressed him, taught him, and loved him, Elizabeth Hess weaves an unforgettable tale of an extraordinary and charismatic creature. His story will move and entertain at the same time that it challenges us to ask what it means to be human, and what we owe to the animals who so enrich our lives.

Publishers Weekly

In what is surely one of the most memorable and intelligent recent books about animal-human interaction, Hess (Lost and Found: Dogs, Cats and Everyday Heroes at a Country Animal Shelter) tells the story of Nim Chimpsky, who in the 1970s was the subject of an experiment begun at the University of Oklahoma to find out whether a chimp could learn American Sign Language-and thus refute Noam Chomsky's influential thesis that language is inherent only in humans. Nim was sent to live with a family in New York City and taught human language like any other child. Hess sympathetically yet unerringly details both the project's successes and failures, its heroes and villains, as she recounts Nim's odyssey from the Manhattan town house to a mansion in the Bronx and finally back to Oklahoma, where he was bounced among various facilities as financial, personal and scientific troubles plagued the study. The book expertly shows why the Nim experiment was a crucial event in animal studies, but more importantly, Hess captures Nim's "legendary charm, mischievous sense of humor, and keen understanding of human beings." This may well be the only book on linguistics and primatology that will leave its readers in tears over the life and times of its amazing subject. (Mar. 4)
