King:A Life, the biography by Jonathan Eig, provides a fresh perspective into the life of one of America's most important activists. From his upbringing in Atlanta's Old Fourth Ward neighborhood to his path through university and the frontlines of the Montgomery bus boycott, Martin Luther King, Jr.'s career and impact is explained through his faith and relationships. In today's episode, Eig speaks to NPR's Steve Inskeep about how Dr. King rose to prominence at such a young age, and how he maintained his spirituality through deep scrutiny and surveillance.
