Assassination and Death. Four sitting Presidents have been assassinated while in office: Abraham Lincoln, James Abram Garfield (1881), William McKinley (1897-1901), and John F. Kennedy (1961-63).
Lincoln was the first American president to be assassinated. An unsuccessful attempt had been made on Andrew Jackson 30 years before in 1835, and Lincoln had himself been the subject of an earlier assassination attempt by an unknown assailant in August 1864.
