Frances Theresa Densmore (May 21, 1867 – June 5, 1957) was an American anthropologist and ethnographer born in Red Wing, Minnesota. Densmore is known for her studies of Native American music and culture, and in modern terms, she may be described as an ethnomusicologist. As a child Densmore developed an appreciation of music by listening to the nearby Dakota Indians. She studied music at Oberlin College for three years. During the early part of the twentieth century, she worked as a music teacher with Native Americans nationwide, while also learning, recording, and transcribing their music, and documenting its use in their culture. She helped preserve their culture in a time when government policy was to encourage Native Americans to adopt Western customs. Densmore began recording music officially for the Smithsonian Institution's Bureau of American Ethnology (BAE) in 1907. In her fifty-plus years of studying and preserving American Indian music, she collected thousands of recordings. Many of the recordings she made on behalf of the BAE now are held in the Library of Congress. While her original recordings often were on wax cylinders, many of them have been reproduced using other media and are included in other archives. The recordings may be accessed by researchers as well as Tribal delegations. Some of the Tribes she worked with include the Ojibwe, the Mandan, Hidatsa, the Sioux, the northern Pawnee in present day Oklahoma, the Tohono O'odham in present day Arizona, Indians of Washington and British Columbia, Ho-Chunk and Menominee of Wisconsin, Pueblo Indigenous peoples of the southwest, including Acoma, Isleta, Cochiti, and Zuni, the Seminole in present day Florida, and Kuna in Panama. Densmore frequently was published in the journal American Anthropologist, contributing consistently throughout her career. Her manuscript A Study of Some Michigan Indians (1949) was the first publication in the University of Michigan Press American Anthropologist monograph series. She wrote The Indians and Their Music in 1926.
