Sarah the chimpanzee was the primary participant in David Premack’s language studies initiated at University of California at Santa Barbara in 1967. The first author was an undergraduate assistant training Sarah from 1967 to 1969. This article describes some of the early work with Sarah and our recent search for her. Sarah’s whereabouts during the intervening years, and subsequent reunion with her in 2016 at Chimp Haven, a chimpanzee sanctuary in Louisiana, are described. It was found that despite her illness, Sarah engaged with the first author and demonstrated that she remembered him and the mechanics of the communication procedure that served as the foundation for testing Sarah’s cognitive reasoning abilities as they pertained to language. There was no evidence she remembered any of the 5 symbolic nouns that were presented during a matching-to-sample procedure. The authors expressed their gratitude to the staff at Chimp Haven for the excellent care of Sarah.
