[edit] History

The language was developed by Ernst von Glasersfeld and used by Duane Rumbaugh and Sue Savage-Rumbaugh of Georgia State University while working with primates at the Yerkes National Primate Research Center of Emory University in Atlanta, Georgia teaching them to communicate by means of lexigram board, a computerized array of keys labeled with lexigrams. The first ape that from 1973 was trained to communicate in Yerkish was Lana.
