Kanzi

Kanzi (October 28, 1980 – March 18, 2025) was a male bonobo who was the subject of numerous studies on great ape language and cognition. According to Sue Savage-Rumbaugh, a primatologist who has studied the bonobo since the 1990s, Kanzi exhibited advanced linguistic aptitude.

Kanzi is well known for his noteworthy cognitive abilities. He had a very well-documented linguistic understanding of the human language. He is believed to be the first non-human great ape to understand and comprehend spoken English. In addition, he was also heavily documented for his understanding and usage of symbols to communicate, usually through lexigrams and partial ASL. The vast amount of information that researchers gathered from Kanzi created a significant impact for the fields of linguistics and cognitive science. Kanzi's behavior and abilities have been the topic of research published in scientific journals, as well as reports in popular media. He died in 2025, in Des Moines, Iowa.
