Joseph Medicine Crow, a Native American historian and the last war chief of the Crow Tribe of Montana, has died. He was 102.

Medicine Crow earned the title war chief "for his deeds in Europe in World War II, which included stealing enemy horses and showing mercy on a German soldier he could have killed," Montana Public Radio's Eric Whitney reports.

He was also a living link to the 1876 Battle of the Little Bighorn, having heard direct testimony from someone who took part in the battle and later chronicling it as a historian.

"He is the last person alive to receive direct oral testimony from a participant in the Battle of the Little Bighorn: his grandfather was a scout for General George Armstrong Custer," the White House said in a statement when it honored Medicine Crow with the Presidential Medal of Freedom, the nation's highest civilian honor, in 2009.

"Wearing war paint beneath his uniform and a sacred feather beneath his helmet, Joseph Medicine Crow completed the four battlefield deeds that made him the last Crow war chief," President Obama said during the ceremony. "Dr. Medicine Crow's life reflects not only the warrior spirit of the Crow people, but America's highest ideals."

Medicine Crow, whose Crow Tribe name was "High Bird," was also the first member of his tribe to earn a master's degree, Eric says. He went on to receive several honorary doctorates.

"Joe was a true American hero," Darren Old Coyote, chairman of the Crow Tribe, told the Billings Gazette. "He was a great man in two worlds."

As The Associated Press reports, Medicine Crow became the official historian for the Crow Tribe shortly after returning from service in World War II. The news service adds:

"With his prodigious memory, Medicine Crow could accurately recall decades later the names, dates and exploits from the oral history he was exposed to as a child, [curator emeritus at the Smithsonian Institution's National Museum of American Indians Herman] Viola said. Those included tales told by four of the six Crow scouts who were at Custer's side at Little Bighorn and who Medicine Crow knew personally.

"Yet Medicine Crow also embraced the changes that came with the settling of the West, and he worked to bridge his people's cultural traditions with the opportunities of modern society."
