Jack Ruby
American nightclub operator who killed American presidential assassin Lee Harvey Oswald

Jack Leon Ruby (born Jacob Rubenstein; c. March 25, 1911 – January 3, 1967) was an American nightclub owner. He murdered Lee Harvey Oswald two days after the assassination of John F. Kennedy. He was born in Chicago, and operated nightclubs in Texas.
Oswald had been arrested for Kennedy's assassination in Dallas, Texas. On November 24, 1963, two days after the assassination, Ruby shot and fatally wounded Oswald in the basement of the Dallas Police Headquarters, and was immediately arrested. The shooting was captured on live television. In March 1964, he was convicted and sentenced to death for Oswald's murder. The conviction was overturned on appeal in 1966, and Ruby was granted a new trial, but he fell ill, was diagnosed with cancer, and died of a pulmonary embolism on January 3, 1967.
In 1964, the Warren Commission concluded that there was no evidence Jack Ruby was part of a conspiracy.

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 24, 2026. The linked authority identifier is Q192519. VIAF identifies the subject as 33274907. The Library of Congress control number is n79063157. 3 of 4 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1911, 1967, 1963 and 1964.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
