Robert Moody Laughlin was an American ethnologist specializing in the study of Mayan language, history, customs, and folklore. He spent the majority of his career working for the Smithsonian Institution, first with the Bureau of American Ethnology, then with the Department of Anthropology. He was a curator emeritus with the department from his retirement in 2006 until his death in 2020. The Robert Moody Laughlin papers (1899-2016, bulk 1954-2016) document his research and professional activities and primarily deal with language and folktales he recorded and studied, as well as the culture and history of the Tzotzil and other Mayan groups in the Chiapas region. His involvement in language education and training, advocacy for the Tzotzil and language and cultural revitalization, and administrative matters at the Smithsonian are also represented. The collection consists of materials created for books and other publications, field notes, research materials, correspondence, administrative files, sound recordings, video recordings, photographs, and electronic records.

The Flora S. Kaplan papers document her field work, research, and professional activities from 1951-2012 (bulk 1969-2012) and primarily deal with her work as the director and founder of New York University's Museum Studies program and her field work in Benin and Mexico. The collection consists of correspondence, research files, book files, photographs, sound recordings, ephemera, and writings.

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.
