Short Bio

Philip Lieberman (1934–2022) was an American cognitive scientist and linguist, professor emeritus at Brown University. Born in Brooklyn, New York, he studied electrical engineering at MIT (BS and MS) and received his doctorate in linguistics there in 1966. He began his academic career at the University of Connecticut in 1967 before joining Brown’s Department of Cognitive, Linguistic, and Psychological Sciences in 1974, where he remained until his retirement in 2012.

Lieberman’s research focused on phonetics and the evolution of human speech, language, and cognition. He carried out pioneering experiments on speech production, studied the vocal tracts of newborn humans, and reconstructed those of Neanderthals to argue about the biological prerequisites for spoken language. Among his more unusual undertakings, he travelled to the Mount Everest base camp to investigate the effects of high altitude on cognitive performance — work that subsequently informed preparations for long-duration crewed space missions.

He published eight books and more than 150 articles over six decades, shaping debates on the relationship between biology and language. Travel with his wife Marcia took him repeatedly to Nepal, where the two of them, together with Lama Ngawang Jorden, produced Buddhist Temple Art, a photographic survey of the wall paintings of three gompas in Mustang published online by the Brown University Library.
