“The March on Washington was a powerful speech,” Lewis said to me recently, over the phone. Lewis was present for that one, too: he spoke on the steps of the Lincoln Memorial minutes before King did. “It was a speech for America, but the speech he delivered in New York, on April 4, 1967, was a speech for all humanity—for the world community.” He added, “I heard him speak so many times. I still think this is probably the best.”
