Charles Alexander Eastman, born Hakadah and later named Ohíyesa, was a Santee Dakota physician, writer, and social reformer who became one of the most influential Native American intellectuals of the early twentieth century. Born in 1858, Eastman possessed Santee Dakota, English, and French ancestry. He dedicated much of his life to bridging the gap between Native and non-Native cultures, establishing himself as a prolific author and speaker on Sioux ethnohistory and American Indian affairs.
Eastman's professional career began in medicine, serving as a physician on reservations in South Dakota. This work exposed him to the systemic challenges facing Native communities, prompting him to become increasingly active in politics and advocacy for Native American rights. As an early Native American historian, he sought to preserve and share the history and traditions of his people from an indigenous perspective.
In addition to his literary and political efforts, Eastman was a dedicated reformer focused on improving the lives of young people. He successfully founded thirty-two Native American chapters of the YMCA and was instrumental in the establishment of the Boy Scouts of America. Through his diverse endeavors as a writer, doctor, and organizer, Eastman left a lasting legacy in the fight for indigenous representation and youth empowerment.
