Harry Hoijer

Harry Hoijer was a linguist and anthropologist who worked on primarily Athabaskan languages and culture. He additionally documented the Tonkawa language, which is now extinct. Hoijer's few works make up the bulk of material on this language. Hoijer was a student of Edward Sapir.
Hoijer contributed greatly to the documentation of the Southern and Pacific Coast Athabaskan languages and to the reconstruction of proto-Athabaskan. Harry Hoijer collected a large number of valuable fieldnotes on many Athabaskan languages, which are unpublished. Some of his notes on Lipan Apache and the Tonkawa language are lost.
Hoijer coined the term "Sapir–Whorf hypothesis".
