Washoe (chimpanzee)

Washoe was a chimpanzee who gained fame for being the first non-human to learn American Sign Language (ASL). Born in 1965, she was raised by researchers Allen and Beatrice Gardner in an experiment to study language acquisition. Over her lifetime, Washoe learned over 350 signs and demonstrated the ability to combine them to express wants and feelings, showcasing advanced cognitive abilities. Her work contributed to discussions about animal intelligence, communication, and the nature of language. Washoe's legacy continues to influence research in primate communication and our understanding of the relationships between humans and other species.
