Charles Eastman was born in 1858 on the Santee Reservation near Redwood Falls, Minnesota and died in 1939. He earned a M.D. degree at Boston University, 1890, and a month after graduating from medical school treated the injuries of survivors of Wounded Knee. He was a strong advocate for Native American causes and worked to set up YMCA units for Indians across the country. He spent much of his life trying to reconcile the opposing values and beliefs of white society and Sioux culture.
