'''Jack Leon Ruby''' (born '''Jacob Leon Rubenstein'''; {{circa}}<ref name=dob1/><ref name=dob2/> March 25, 1911{{spnd}}January 3, 1967) was an American nightclub owner who murdered [[Lee Harvey Oswald]] on November 24, 1963, two days after Oswald [[Assassination of John F. Kennedy|assassinated President John F. Kennedy]]. 

Born in Chicago, Ruby operated nightclubs in [[Texas]]. On November 24, 1963, two days after [[John F. Kennedy|President Kennedy]] was assassinated in Dallas, Ruby shot and mortally wounded Oswald in [[Dallas]] Police Headquarters and was immediately arrested. The shooting happened on live television. Ruby was convicted and sentenced to death. This was overturned on appeal, and he was granted a new trial, but Ruby fell ill, was diagnosed with [[cancer]], and died of a [[pulmonary embolism]] on January 3, 1967.

In 1964, the [[Warren Commission]] concluded that Ruby acted alone in killing Oswald, and that Ruby shot Oswald on impulse in retaliation for the Kennedy assassination.

However, the death of Oswald in police custody so soon after the assassination of President Kennedy led some to question the official version of events.
