# Oswald Lee Harvey Oswald (1939-1963), the presumed assassin of President John F. Kennedy. Oswald allegedly shot Kennedy from a high window of a building in Dallas on November 22, 1963, as Kennedy rode down the street in an open car. Oswald was captured the day of the assassination, but was never tried; two days after Kennedy's death, as Oswald was being moved by police, a nightclub owner from Dallas, Jack Ruby, shot and killed him. A government commission concluded later that Oswald, though active in communist causes, was not part of a conspiracy to kill Kennedy. Some have questioned the findings of the commission.
