Abraham Lincoln at the dedication of the Soldiers National Cemetery in Gettysburg, Pennsylvania, on November 19, 1863. Made from the original glass plate negative at the National Archives which had lain unidentified for 55 years until 1952 when Josephine Cobb recognized Lincoln in the image. To Lincoln's right is bodyguard Ward Hill Lamon. To his far left is Governor Andrew G. Curtin of Pennsylvania. The photograph is estimated to have been taken at about noontime, just after Lincoln arrived, before Edward Everett's arrival and about three hours before Lincoln gave his famous Gettysburg Address. Lincoln's carefully crafted address, secondary to other presentations that day, came to be regarded as one of the greatest speeches in American history. In just over two minutes, Lincoln reiterated the principles of human equality espoused by the Declaration of Independence and proclaimed the Civil War as a struggle for the preservation of the Union sundered by the secession crisis, with "a new birth of freedom", that would bring true equality to all of its citizens. Lincoln also redefined the Civil War as a struggle not just for the Union, but also for the principle of human equality. Photographed by David Bachrach, the image has been cropped and cleaned.
