Francis La Flesche (1857–1932), a Native American ethnologist and writer of Omaha and Osage heritage, was the first professional Native American anthropologist, working closely with Alice C. Fletcher at the Smithsonian Institution. His research centered on recording Omaha and Osage cultures through in-depth ethnographic studies, ritual examinations, and wax cylinder recordings of traditional songs.
La Flesche wrote foundational texts such as The Omaha Tribe (1911) and several volumes on Osage ceremonies, highlighting their intellectual depth. Although his opera Da O Ma (1912) was never staged, his stories and linguistic works, published after his death such as Ke-ma-ha: The Omaha Stories (1998), emphasize his role as a link between indigenous knowledge and academic anthropology.
