Eastman, Charles A.: - Charles Alexander Eastman (1858-1939), also known as Hakadah and later as Ohiyesa, was a prominent Native American author, physician, and activist. He was born in a Dakota Sioux community near Redwood Falls, Minnesota, to a mixed-race family of Dakota and European descent. Orphaned at an early age during the Dakota War of 1862, Eastman was raised in the traditional Dakota Sioux manner until the age of 15, when he attended formal schooling in the East. Eastman went on to become one of the first Native Americans to graduate from medical school, earning his medical degree from Boston University in 1889. He dedicated much of his life to advocating for Native American rights and education, working as a physician on reservations and serving as a government Indian inspector. Eastman is best known for his writings that aimed to preserve and promote understanding of Native American culture and history. His works include several books such as ""Indian Boyhood"" (1902), ""Old Indian Days"" (1907), and ""The Soul of the Indian"" (1911), which were instrumental in shaping non-Native perceptions of Native American life and spirituality. These books often drew from his personal experiences and upbringing, offering insights into traditional Dakota Sioux customs, spirituality, and values. Charles A. Eastman's legacy extends beyond his literary contributions; he played a significant role in bridging cultural divides and promoting dialogue between Native and non-Native communities. His writings continue to be studied for their historical significance and their role in preserving Native American heritage.
