Chantek

Chantek (December 17, 1977 – August 7, 2017), born at the Yerkes National Primate Research Center in Atlanta, Georgia, was a male hybrid Sumatran/Bornean orangutan who demonstrated a number of intellectual skills, including the use of several signs adapted from American Sign Language (ASL). American anthropologists Lyn Miles and Ann Southcombe worked with Chantek. In 1997, he was transferred to Zoo Atlanta, where he lived for another twenty years.
