This black and white photograph of President Abraham Lincoln and his youngest son Tad was taken by Alexander Gardner on February 5, 1865. The portrait photograph was originally a gelatin silver print and was taken at Gardner's Gallery in Washington, D.C. This photograph was from the last series of images taken of President Lincoln, previously thought to have been taken on April 10, 1865, just four days before his assassination at Ford's Theater. Subsequent research has discovered the more likely date of creation to have been in February.
