The Beatrice Medicine papers, 1913-2003 (bulk 1945-2003), document the professional life of Dr. Beatrice "Bea" Medicine (1923-2005), a member of the Standing Rock Sioux tribe, anthropologist, scholar, educator, and Native rights activist. The collection also contains material collected by or given to Medicine to further her research and activism interests. Medicine, whose Lakota name was Hinsha Waste Agli Win, or "Returns Victorious with a Red Horse Woman," focused her research on a variety of topics affecting the Native American community: 1) mental health, 2) women's issues, 3) bilingual education, 4) alcohol and drug use, 5) ethno-methodologies and research needs of Native Americans, and 6) Children and identity issues. The collection represents Medicine's work as an educator for universities and colleges in the United States and in Canada, for which she taught Native American Studies courses. Additionally, because of the large amount of research material and Medicine's correspondence with elected U.S. officials and Native American leaders, and records from Medicine's involvement in Native American organizations, the collection serves to represent issues affecting Native Americans during the second half of the 20th century, and reflects what Native American leaders and organizations did to navigate and mitigate those issues. Collection materials include correspondence; committee, conference, and teaching material; ephemera; manuscripts and poetry; maps; notes; periodicals; photographs; training material; and transcripts.
