lla Cara Deloria came to New York to study at Teachers College, but ended up meeting and forging an intellectual partnership with anthropologist Franz Boas, who made Columbia-Barnard a key center for anthropology and linguistics in the early 20th century. Born on the Yankton Sioux Reservation and raised on Pine Ridge in South Dakota, Deloria was a native speaker of several Dakota language varieties, which she then documented through fieldwork in her landmark 1932 _Dakota Texts _and 1941 Dakota Grammar (co-authored with Boas).
