Frans' Sentientist Conversation with me is on the Sentientism YouTube and podcast.

Frans was a primatologist and ethologist. He was the Charles Howard Candler Professor of Primate Behavior in the Department of Psychology at Emory University in Atlanta, Georgia, director of the Living Links Center at the Yerkes National Primate Research Center at Emory and the author of numerous books including "Chimpanzee Politics", "Our Inner Ape" and "The Bonobo and the Atheist". He featured in TV/radio productions and TED talks viewed by tens of millions of people. His research centered on primate social behavior, including conflict resolution, cooperation, inequity aversion, and food-sharing. He was a member of the United States National Academy of Sciences and the Royal Netherlands Academy of Arts and Sciences.

While Frans did largely grant moral consideration based on sentience he did still consume some non-mammalian sentient animal products. Frans was an atheist and had a naturalistic worldview. He wrote extensively on the evolutionary histories and naturalistic bases for ethics.
