Mary Rosamond Haas was a highly influential American linguist. Linguistics is the scientific study of language and its structure. Haas specialized in North American indigenous languages and the Thai language. She was also an expert in historical linguistics, which examines how languages change over time. Her work was vital for preserving languages that were in danger of disappearing. Because of her immense contributions, she served as the president of the Linguistic Society of America in 1963.

Haas utilized a primary research method known as fieldwork. Fieldwork involves traveling to specific locations to study languages directly from native speakers. During the 1930s, she worked closely with Sesostrie Youchigant to document the Tunica language. She also performed critical fieldwork with Watt Sam and Nancy Raven. They were the final two native speakers of the Natchez language in Oklahoma. Her extensive, unpublished field notes remain the most reliable source of information for the now extinct Natchez language.

Her academic training provided a strong foundation for her research career. She began her graduate studies in comparative philology at the University of Chicago. There, she studied under the renowned linguist Edward Sapir. She later followed Sapir to Yale University to continue her advanced education. In 1935, at age 25, she earned her PhD from Yale. Her dissertation focused on the complex grammar of the Tunica language.

Haas spent a significant portion of her professional life at the University of California, Berkeley. During World War II, she developed a Thai language program for the Army Specialized Training Program. This was because the United States government viewed Southeast Asian language skills as essential for the war effort. In 1948, she became an assistant professor in the Department of Oriental Languages. She later became a founding member of the Berkeley Department of Linguistics in 1953.

As a leader at Berkeley, Haas held several important administrative roles. She served as a long-term chair of the linguistics department. From 1953 to 1977, she directed the Survey of California Indian Languages. In this role, she provided guidance for many important linguistic studies. She also published the authoritative Thai-English Students' Dictionary in 1964. This resource is so effective that it remains in use by students today.

Haas was perhaps most impactful through her dedication to teaching and mentorship. She supervised fieldwork for more than 100 doctoral students. This number is notable because her student, Karl V. Teeter, noted she trained more Americanist linguists than Edward Sapir and Franz Boas combined. She advised nearly 50 dissertations through her work with the Survey of California Indian Languages. Many of her students, such as William Bright and Catherine Callaghan, became highly influential scholars in their own right.

Her career was marked by numerous prestigious honors and recognitions. In 1964, she was awarded a Guggenheim Fellowship. She was elected a fellow of the American Academy of Arts and Sciences in 1974. In 1978, she achieved membership in the National Academy of Sciences. Additionally, she received honorary doctorates from Northwestern University, the University of Chicago, Earlham College, and Ohio State University. Her life's work helped bridge the gap between different cultures through the study of their spoken words.
