Abraham Lincoln, the 16th President of the United States, in a head-and-shoulders portrait taken by photographer Alexander Gardner on February 5, 1865. Traditionally called "last photograph of Lincoln from life", this final photo in Lincoln's last photo session was long thought to have been made on April 10, 1865, but more recent research has indicated the earlier date in February. The crack comes from the original negative, which was broken and discarded back in 1865. The entirety of the American Civil War took place while Lincoln was in office, starting a month after he was elected, and ending just days before his assassination in April of 1865.
