Gettysburg Address
William R. Rathvon is the only known eyewitness of the Gettysburg Address to have left an audio recording of what he remembered. One year before he died in 1939, Rathvon's remarks were recorded on February 12, 1938. It included his reading the address itself. The title of the record was "I Heard Lincoln That Day - William R. Rathvon, TR Productions". The National Public Radio (NPR) discovered a copy during a "Quest for Sound" project in 1999. NPR allows people to hear the record around Lincoln's birthday.
