The Ethel Austin Martin Papers span her personal life, academic background, professional career, and enduring legacy in the field of nutrition. The collection includes correspondence, publications, autobiographical writings, oral history transcripts, photographs, ephemera, awards, and memorabilia. It documents her education from elementary school through graduate studies at Columbia University, her work as an educator and director of nutrition services at the National Dairy Council, and her authorship of several widely used nutrition textbooks. Also included are materials related to her professional affiliations, recognitions, and involvement in national and international conferences. A significant portion of the collection relates to her long-standing relationship with South Dakota State University, particularly her efforts to establish the Ethel Austin Martin Program in Human Nutrition. Items such as diplomas, certificates, calling cards, and a blanket worn in the first Hobo Day parade help illuminate her personal story, while her correspondence and writings reflect her contributions to nutrition education and public health.
