Kenneth L. Hale

Kenneth Locke Hale (August 15, 1934 – October 8, 2001) was a linguist at the Massachusetts Institute of Technology who studied a huge variety of previously unstudied and often endangered languages—especially indigenous languages of North America, Central America and Australia. Languages investigated by Hale include Navajo, O'odham, Warlpiri, and Ulwa, among many others.
