Dallas is the third-largest city in [Texas](/places/texas/) and the ninth-largest in the [United States](/places/united-states/), a major commercial and financial center in the southern Great Plains. Its significance for this vault is almost entirely defined by the assassination of President [John F. Kennedy](/people/john-f-kennedy/) on November 22, 1963, and the network of relationships that converged in the city at that moment.[^1]

### The Kennedy Assassination

President Kennedy was shot while riding in a motorcade through Dealey Plaza in downtown Dallas at approximately 12:30 PM on November 22, 1963. Governor John Connally of Texas, riding in the same limousine, was also wounded. Kennedy was taken to Parkland Memorial Hospital, where he was pronounced dead at 1:00 PM. Vice President [Lyndon B. Johnson](/people/lyndon-b-johnson/) was sworn in as president aboard Air Force One at 2:38 PM.[^1]

[Lee Harvey Oswald](/people/lee-harvey-oswald/), 24, a former Marine who had defected to the [Soviet Union](/places/soviet-union/) and returned to the United States, was arrested in the Texas Theatre approximately 80 minutes after the assassination and charged with Kennedy's murder and the separate murder of Dallas police officer J.D. Tippit. Oswald denied the charges, claiming he was "just a patsy." He was shot and killed by Dallas nightclub owner [Jack Ruby](/people/jack-ruby/) in the basement of the Dallas Police Department on November 24, 1963, while being transferred to the county jail.[^2]

### Jack Ruby

[Jack Ruby](/people/jack-ruby/) (born Jacob Leon Rubenstein) operated the Carousel Club, a striptease club on Commerce Street in Dallas. Ruby had documented connections to organized crime figures in [Chicago](/places/chicago/), [New Orleans](/places/new-orleans/), and Dallas, including contacts traced to [Carlos Marcello](/people/carlos-marcello/)'s Mafia organization in Louisiana and to [Santos Trafficante, Jr.](/people/santos-trafficante-jr/) in [Florida](/places/florida/). Ruby's telephone records in the months before the assassination showed calls to figures associated with organized crime and Teamsters Union officials. The [House Select Committee on Assassinations](/events/hsca/) (HSCA), reporting in 1979, concluded that Ruby's shooting of Oswald had the hallmarks of a silencing operation.[^2]

Ruby was convicted of murder in March 1964 and sentenced to death; the conviction was later overturned on procedural grounds. Ruby was diagnosed with cancer in late 1966 and died in Dallas on January 3, 1967.

### Oswald's Dallas Connections

Oswald's activities in Dallas and nearby Irving, Texas in the months before the assassination were investigated intensively. He worked at the Texas School Book Depository on Elm Street, overlooking the motorcade route, having been placed there through the assistance of Dallas White Russian emigre community figures. His contacts during this period - including the circumstances of his Fair Play for Cuba Committee activities, his apparent intelligence connections, and his contacts with figures including [George de Mohrenschildt](/people/george-de-mohrenschildt/) - have been the subject of continuing investigation and analysis.[^1]

The [Warren Commission](/events/warren-commission/) concluded in September 1964 that Oswald acted alone and that Ruby acted alone. The HSCA's 1979 conclusion that there was "probably a conspiracy" based on acoustical evidence of a second shooter in Dealey Plaza - evidence later disputed by the National Academy of Sciences - has never been officially resolved. Kennedy's assassination remains one of the most extensively analyzed and contested events in American history.[^2]
