a watch fob of gold-bearing quartz, mounted in gold;
When Abraham Lincoln was shot at Ford’s Theatre in Washington, D.C. on April 14, 1865, he was carrying two pairs of spectacles and a lens polisher, a pocketknife, a watch fob, a linen handkerchief, and a brown leather wallet containing a five-dollar Confederate note and nine newspaper clippings, including several favorable to the president and his policies. Given to his son Robert Todd upon Lincoln’s death, these everyday items, which through association with tragedy had become like relics, were kept in the Lincoln family for more than seventy years. They came to the Library in 1937 as part of the gift from Lincoln’s granddaughter, Mary Lincoln Isham,.
