The chimpanzee, also known as simply the chimp, is a species of great ape native to the forests and savannahs of tropical Africa. It has four confirmed subspecies and a fifth proposed one. When its close relative the bonobo was more commonly known as the pygmy chimpanzee, this species was often called the common chimpanzee or the robust chimpanzee. The chimpanzee and the bonobo are the only species in the genus Pan. Evidence from fossils and DNA sequencing shows that Pan is a sister taxon to the human lineage and is humans' closest living relative. The chimpanzee is covered in coarse black hair, but has a bare face, fingers, toes, palms of the hands, and soles of the feet. It is larger and more robust than the bonobo, weighing 40–70 kg (88–154 lb) for males and 27–50 kg (60–110 lb) for females and standing 150 cm.
Neam "Nim" Chimpsky was a chimpanzee and the subject of an extended study of animal language acquisition at Columbia University. The project was led by Herbert S. Terrace with the linguistic analysis headed up by psycholinguist Thomas Bever. Within the context of a scientific study, Chimpsky was named as a pun on linguist Noam Chomsky, who posits that humans are "wired" to develop language.
Washoe was a female common chimpanzee who was the first non-human to learn to communicate using American Sign Language (ASL) as part of an animal research experiment on animal language acquisition.
Yerkish is an artificial language developed for use by non-human primates. It employs a keyboard whose keys contain lexigrams, symbols corresponding to objects or ideas.
Kanzi, also known by the lexigram , is a male bonobo who has been the subject of several studies on great ape language. According to Sue Savage-Rumbaugh, a primatologist who has studied the bonobo throughout his life, Kanzi has exhibited advanced linguistic aptitude.
Research into great ape language has involved teaching chimpanzees, bonobos, gorillas and orangutans to communicate with humans and each other using sign language, physical tokens, lexigrams, and imitative human speech. Some primatologists argue that the use of these communication methods indicate primate "language" ability, though this depends on one's definition of language.
Lana was a female chimpanzee, the first to use lexigrams in language research. She was born at the Yerkes National Primate Research Center of Emory University, and the project she was allocated to when 1 year old, the LANguage Analogue project led by Duane Rumbaugh, was named after her with the acronym LANA because the project team felt that her identity was well worth preserving.
Chantek, born at the Yerkes National Primate Research Center in Atlanta, Georgia, was a male hybrid Sumatran/Bornean orangutan who acquired the use of a number of intellectual skills, including American Sign Language (ASL), taught by American anthropologists Lyn Miles and Ann Southcombe. In Malay and Indonesian, cantik means "lovely" or "beautiful".
The Chimpanzee and Human Communication Institute (CHCI) was located on the campus of Central Washington University in Ellensburg, Washington. CHCI included a sanctuary for chimpanzees who have learned to communicate with humans and each other using American Sign Language. CHCI's director was Mary Lee Jensvold. It was founded by former co-directors Roger Fouts and Deborah Fouts. The institute was closed in 2013 when the remaining chimpanzees were transferred to facilities in Quebec, Canada and the building the facility was housed in, was demolished in 2018. Portions of the specialized structures used to house the chimps were dismantled and moved to the Chimpanzee Sanctuary Northwest in Cle Elum, for future use.
The Mind of an Ape is a 1983 book by David Premack and his wife Ann James Premack. The authors argue that it is possible to teach language to (non-human) great apes. They write: "We now know that someone who comprehends speech must know language, even if he or she cannot produce it."
Deborah Fouts was the co-director of the Chimpanzee and Human Communication Institute (CHCI). CHCI was the home of Washoe, the first non-human to acquire a human language, and three other chimpanzees who use the signs of American Sign Language to communicate with each other and their human caregivers. She is an Adjunct Assistant Professor of Psychology (Research) at Central Washington University in Ellensburg, Washington. She is married to former co-director, now retired Roger Fouts.
Mary Lee Jensvold is a senior lecturer at Central Washington University. She was the Director of the Chimpanzee and Human Communication Institute (CHCI) located on the campus of Central Washington University. CHCI was the home of the chimpanzee Washoe and four other chimpanzees who use the signs of American Sign Language to communicate with one another and their human caregivers.
Roger S. Fouts is a retired American primate researcher. He was co-founder and co-director of the Chimpanzee and Human Communication Institute (CHCI) in Washington, and a professor of psychology at the Central Washington University. He is best known for his role in teaching Washoe the chimpanzee to communicate using a set of signs taken from American sign language.
The Fauna Foundation is the only chimpanzee sanctuary in Canada. Located just outside Chambly, on the South Shore of Montreal, the story of Fauna started in 1990 by Gloria Grow and Dr. Richard Allan on their 150-acre (0.61 km2) farm. Later in 1997, it became the Fauna Foundation. Its primary objective, the rescue and care of chimpanzees who have been used in research, began in the wake of the shutdown of LEMSIP.
Gua was a chimpanzee raised as though she were a human child by scientists Luella and Winthrop Kellogg alongside their infant son Donald. Gua was the first chimpanzee to be used in a cross-rearing study in the US.
Panbanisha, also known by the lexigram , was a female bonobo that featured in studies on great ape language by Professor Sue Savage-Rumbaugh. Her name is Swahili for "to cleave together for the purpose of contrast."
Richard Lynch Garner was an American researcher who studied the language of primates, especially chimpanzees, and pioneered the use of playback devices in this kind of research. His theories and findings have been superseded by more recent research, but his work has been an inspiration to such notable scientists as Robert Yerkes and John Peabody Harrington.
Beatrix Tugendhut Gardner was an Austrian zoologist who became well known for the research that she conducted in the United States. She is most well known for her sign language studies with Washoe the chimpanzee, who was the first ape to learn sign language.
Rosalía Abreu was a Cuban philanthropist and animal-keeper who was the first person to successfully breed chimpanzees in captivity. In 1926, she initially supported research proposed by Ilya Ivanov to breed a humanzee, although she later retracted the decision to involve her primates in the experiment. American eugenicist Robert Yerkes worked with Abreu and based some of his research on developments she had made in primate care and purchased many of her primates.
