Duane M. Rumbaugh (1929-2017).

Presents an obituary of Duane M. Rumbaugh (1929-2017). Rumbaugh was an experimental psychologist known for his many contributions toward understanding primate learning and behavior. His ape-language research with Lana and other chimpanzees, comparative studies of quantitative and qualitative hallmarks of primate intelligence, and numerous methodological innovations helped usher in the field of comparative cognition. Rumbaugh's scientific legacy is extensive. The computerized language keyboard invented for the Lana Project would subsequently be employed to teach other nonhuman primates, as well as humans with intellectual challenges to communicate.
