Joe Medicine Crow, a revered historian and the last surviving war chief of Montana’s Crow tribe, died Sunday, family members confirmed. He was 102. The decorated WWII veteran attended the University of Southern California and, in 1939, became the first of his tribe to get a master’s degree. Medicine Crow authored several books and is best known for his work relating to the Battle of the Little Bighorn. He received the Presidential Medal of Freedom in 2009 from President Obama. “His contributions to the preservation of the culture and history of the First Americans are matched only by his importance as a role model to young Native Americans across the country,” Obama said at the time.
