Within hours of President John F. Kennedy's assassination on Nov. 22, 1963, most Americans were familiar with the name Lee Harvey Oswald. Certain images of him - posing with a rifle, recoiling from Jack Ruby's gun - have been ingrained in the nation's memory. Yet to this day, he remains an enigma. Some of the questions and answers about him:
Q: Did Oswald kill Kennedy? Did he act alone?
A: The Warren Commission, established by President Lyndon Johnson to investigate the assassination, concluded in 1964 that Oswald acted alone, firing three shots from a window in his Dallas workplace, the Texas School Book Depository. Many Americans have questioned this conclusion. In 1978, the House Select Committee on Assassinations ended its own inquiry by finding that Kennedy "was probably assassinated as a result of a conspiracy."
Q: What was Oswald's childhood like?
A: Unstable. By the time he turned 17 and joined the Marines, he had lived at more than 20 different addresses and attended a dozen schools. He was born in New Orleans on Oct. 18, 1939, two months after his father died of a heart attack, spent time in an orphanage as a 3-year-old, and moved with his family to Dallas in 1944. He and his mother moved in 1952 to New York City, where he had run-ins with truant officers and underwent psychiatric observation. Two years later, they moved back to New Orleans.
Q: How did he fare in the Marines?
A: Erratically. In early phases of his service at U.S. bases, he got good performance evaluations and qualified as a sharpshooter after marksmanship training. But he was court-martialed twice while stationed in Japan, first after wounding himself with an unauthorized pistol and later after a bar fight. He tried to teach himself Russian, and -- at the height of the Cold War -- would occasionally speak favorably of Marxism and the Soviet Union.
Q: Did he try to defect to Russia?
A: Yes. He obtained an early discharge from the Marines, and in 1959 he traveled to Finland and boarded a train to Moscow. Soon after arrival, he told his guide he wanted to defect. Russian authorities initially rebuffed him (he slit his wrist in response) but eventually allowed him to stay and sent him to the city of Minsk to work at an electronics factory. In March 1961, Oswald met Marina Prusakova, a 19-year-old pharmacology student. They married within six weeks and had a child in February 1962. That May, after expressing weariness with life in Russia, Oswald and his wife applied at the American Embassy in Moscow for documents enabling her to immigrate to the U.S. They settled in Dallas that fall.
Q: Wasn't Oswald linked to another assassination plot?
A: On April 10, 1963, a gunman fired a rifle through a window of the Dallas home of Maj. Gen. Edwin Walker, a fervent anti-communist and segregationist who resigned from the Army after being reprimanded for giving troops right-wing propaganda. Walker, working at a desk in his home, was slightly injured by fragments. The Warren Commission later concluded Oswald was the gunman.
Q: What's the Cuban connection in Oswald's life?
A: In late April 1963, just days after the attack on Walker, Oswald went to New Orleans and spent the summer there. He printed and distributed leaflets in support of Cuba's Communist leader, Fidel Castro, and got into a street fight with anti-Castro demonstrators. Yet the leaflets bore an address of a local anti-Castro operation connected to a former FBI agent. That September, Oswald took a bus to Mexico City and visited the Cuban and Soviet embassies in an unsuccessful effort to get clearance to travel to Russia via Cuba.
Q: How was Oswald arrested on Nov. 22?
A: The Warren Commission said Oswald left the book depository moments after shots were fired from the sixth floor, returned by bus and cab to his rooming house, then ventured out again -- soon encountering a Dallas police officer who stopped him based on descriptions of the assassination suspect. According to the commission, Oswald fatally shot Patrolman J.D. Tippit with a handgun, then fled into a nearby movie theater, where he was soon arrested.
Q: What was playing that day at the Texas Theatre?
A: A double bill of "War is Hell" and "Cry of Battle."
Q: Who was Jack Ruby?
A: Ruby was a Dallas nightclub owner well acquainted with many police officers. As Oswald was being transferred from police headquarters to the county jail on Nov. 24, Ruby shot him in the chest from close range. Oswald was rushed unconscious to Parkland Memorial Hospital -- where doctors had tried to save Kennedy's life two days earlier -- and died there at 1:07 p.m. Ruby was convicted of murder and sentenced to death. He appealed and was granted a new trial, but died of lung cancer before a trial date was set. Ruby said he was angered by Kennedy's assassination and wanted to spare Jacqueline Kennedy the ordeal of a trial for Oswald. Skeptics, noting that Ruby had some connections with underworld figures, have suggested his shooting of Oswald was part of a broader conspiracy.
Q: Did the Warren Commission specify a motive for Oswald killing Kennedy?
A: No. Oswald "was moved by an overriding hostility to his environment," the report said. "He does not appear to have been able to establish meaningful relationships with other people. He was perpetually discontented with the world around him. Long before the assassination he expressed his hatred for American society and acted in protest against it."
