- In 1952, the chief of the Still Photo section at the National Archives, Josephine Cobb, discovered a glass plate negative taken by Mathew Brady of the speaker’s stand at Gettysburg on the day of its dedication as a National Cemetery. Edward Everett would speak from that stand later in the afternoon for two straight hours. Moments later, a tall, gaunt Abraham Lincoln would stand up and deliver a ten sentence speech in two minutes. It was the Gettysburg Address.
