This is the .44 caliber derringer pistol that John Wilkes Booth used to assassinate Abraham Lincoln on April 14, 1865. I photographed it in the museum at Ford's Theater in Washington, DC. At 6 inches long with a 2 1/2-inch barrel, it weighs only 8 ounces and was one of the most popular concealed handguns of the time. The trigger and mountings were made of German silver, and there is a box in the grip for an extra percussion cap. The weapon was recovered after Booth dropped it in the Presidential box after firing it at point-blank range into the President's head. Lincoln died early the next day.
