Barack Obama winning a Nobel Peace Prize 10 months into his presidency has, if nothing else, generated some serious controversy and healthy debate. So it’s ironic, perhaps, that October 14 marks the 45th anniversary of another African American's stunning Nobel win: In 1964, Martin Luther King Jr. won his own Peace Prize—and while, at 35, he was the award's youngest-ever recipient, no one looking at what King achieved in the decade leading up to his Nobel could possibly challenge the rightness of the honor.
