Leonie Sophie Treier is a museum anthropologist focusing on the histories of collecting and representing Native American material culture in museums and beyond. Supported by a Smithsonian Institution predoctoral fellowship at the National Museum of Natural History in Washington, DC, her dissertation research studies the collection of material culture belonging to George Catlin’s Indian Gallery and focuses on material fabrications consisting of (de)construction, repurposing, and adding decorative elements of Native North American and non-Native source material, among other modifications, undertaken on a variety of items. She analyzes how specific disciplinary concerns have informed scholarly and museological (dis)engagement with this materially hybrid and ethnographically ambiguous collection, thereby shedding light on both historical and contemporary constructions of Native American cultural identity and change under colonialism. She holds an MPhil in Visual, Material, and Museum Anthropology from the University of Oxford, in the context of which she worked with residents of Santa Clara Pueblo, New Mexico, on a photographic album created by Barbara Freire-Marreco. She has published in The Journal of Museum Anthropology, Museum Worlds, and Museum Anthropology Review.
