Early work in linguistics Haas undertook graduate work on
comparative philology at the
University of Chicago. She studied under
Edward Sapir, whom she later followed to
Yale. She began a long career in linguistic fieldwork by studying various languages during the summer months. Shortly after, Haas conducted fieldwork with
Watt Sam and
Nancy Raven, the last two native speakers of the
Natchez language in
Oklahoma. Her extensive unpublished field notes have constituted the most reliable source of information on the now dead language. She conducted extensive fieldwork on the
Muskogee language, and was the first modern linguist to collect extensive texts in the language. Her Muskogee texts were published after her death in a volume that was edited and translated by Jack B. Martin, Margaret McKane Mauldin, and Juanita McGirt.
Career at the University of California, Berkeley During
World War II, the United States government viewed the study and teaching of Southeast Asian languages as important to the war effort, and under the auspices of the
Army Specialized Training Program at the
University of California at Berkeley, Haas developed a program to teach the
Thai language. Her authoritative ''Thai-English Students' Dictionary'', published in 1964, is still in use. In 1948, she was appointed assistant professor of Thai and Linguistics at the
University of California, Berkeley Department of
Oriental Languages, an appointment she attributed to
Peter A. Boodberg, whom she described as "ahead of his time in the way he treated women scholars—a scholar was a scholar in his book". She retired from Berkeley in 1977 and in 1984 was elected a Berkeley Fellow. Mary Haas died at her home in Berkeley, California, on May 17, 1996, at the age of 86. that she trained more
Americanist linguists than her former instructors
Edward Sapir and
Franz Boas combined: she supervised fieldwork in Americanist linguistics by more than 100 doctoral students. As a founder and director of the
Survey of California Indian Languages, she advised nearly fifty dissertations, including those of many linguists who were later influential in the field, including
