On September 12, 1962, Martin Luther King, Jr. gave a speech at the Park-Sheraton Hotel in New York City to commemorate the centennial of the Preliminary Emancipation Proclamation. It was thought that the only record of the speech was a typewritten script annotated by an audio engineer, but 41 years later — in November 2013 — an intern at the New York State Museum in Albany uncovered the only known recording, which can be heard here.
