Many people remember Dr. King as an idealist, but he was very grounded. The film “Selma” (which I highly recommend) begins with MLK dressing for his Nobel prize ceremony. Right there, at the beginning of the movie we see our hero as very human. “Selma” is an amazing film because Hollywood films about the Movement are usually either sentimentalize or have a white hero. “Selma” keeps it real.
MLK’s speech on receiving the Nobel prize was one of his best, known as the World House speech. Here is a link to the text of that speech and a recording of a bit of it. I yield the rest of my time to Dr. King.
