John F. Kennedy, the 35th president of the United States, was assassinated while riding in a presidential motorcade through Dealey Plaza in Dallas, Texas, on November 22, 1963. Kennedy was in the vehicle with his wife Jacqueline, Texas governor John Connally, and Connally's wife Nellie, when he was fatally shot from the nearby Texas School Book Depository by Lee Harvey Oswald, a former U.S. Marine. The motorcade rushed to Parkland Memorial Hospital, where Kennedy was pronounced dead about 30 minutes after the shooting; Connally was also wounded in the attack but recovered. Vice President Lyndon B. Johnson was hastily sworn in as president two hours and eight minutes later aboard Air Force One at Dallas Love Field.
After the assassination, Oswald returned home to retrieve a pistol; he shot and killed a lone Dallas policeman J. D. Tippit shortly afterwards. Around 70 minutes after Kennedy and Connally were shot, Oswald was apprehended by the Dallas Police Department and charged under Texas state law with the murders of Kennedy and Tippit. Two days later, as live television cameras covered Oswald being moved through the basement of Dallas Police Headquarters, he was fatally shot by Dallas nightclub operator Jack Ruby. Like Kennedy, Oswald was taken to Parkland Memorial Hospital, where he soon died. Ruby was convicted of Oswald's murder, though the decision was overturned on appeal, and Ruby died in prison in 1967 while awaiting a new trial.
