Frans de Waal, 75, Who Believed Apes Had Cognition, Dies so said the obituary by Alex Traub in the New York Times on Saturday, March 23, 2024.

“Frans de Waal, who used his study of the inner life of animals to build a powerful case that apes think, feel, strategize pass down culture and act on moral sentiments – and that humans are not quite as special as many like to think- died on March 14 at his home in Stone Mountain, Ga.”
