John Fitzgerald Kennedy was the 35th President of the United States (1961-1963), and the youngest man elected to office. On November 22, 1963, when he was hardly past his first thousand days in office, JFK was assassinated in Dallas, Texas, becoming also the youngest President to die. His Inaugural Address offered the memorable injunction: “Ask not what your country can do for you–ask what you can do for your country.”
