At the height of the civil rights movement in 1963, these famous words were spoken from the steps of the Lincoln Memorial in Washington, D.C.: “I have a dream that one day this nation will rise up and live out the true meaning of its creed: ‘We hold these truths to be self-evident, that all men are created equal.’” But Martin Luther King Jr., was not the first to raise his voice from those steps with a message of hope for America’s future. That distinction belongs to the world-famous contralto Marian Anderson, whose performance at the Lincoln Memorial on April 9, 1939, made a compelling case for the transformative power of music, and in a place typically associated with the power of words.
