input: Reasoner took part in covering the John F. Kennedy assassination on Friday, November 22, 1963. Walter Cronkite and Charles Collingwood had been switching back and forth to report on the incident for about four hours after Cronkite initially broke the news at 1:40 p.m. EST. Reasoner took over the anchor chair after Collingwood tossed it to him at 5:49 p.m. EST and opened with the repeat of an announcement by Frank Stanton, the president of CBS, which had already been relayed by Collingwood:  He later reported on the arrival of Kennedy's body in Washington, D.C., and provided details regarding Lee Harvey Oswald (who was then accused only of killing Dallas Police Officer J. D. Tippit; he would be accused of killing the president only hours later). Reasoner left the desk when Cronkite returned to anchor CBS Evening News at 6:35 p.m. EST. He reappeared in another studio, approximately two hours later, to narrate a special program called "John F. Kennedy -- A Man of This Century", and he talked about Kennedy's career and the new president, Lyndon B. Johnson and announced the conclusion of CBS's coverage for that day. (Reasoner also anchored the final coverage of the next day, with a CBS News special titled "A Day to Mourn".)  Reasoner's next appearance came two days later, Sunday, and as Reasoner was at the anchor desk, Oswald was shot by Jack Ruby while being moved in the Dallas City Jail. At that very moment, Roger Mudd was filing a report from Washington, describing the President's funeral arrangements.  At this point, CBS abruptly cut back to Reasoner at the newsroom anchor desk with breaking news.  At the time CBS picked up KRLD's live feed of the city jail basement, Oswald was lying on the floor and Dallas Police were apprehending Ruby. KRLD's reporter on the scene, Bob Huffaker, was heard to say, "Oswald has been shot, Oswald has been shot". After the ambulance carrying Oswald sped out of the jail en route to Parkland Hospital, KRLD switched back to CBS in New York, where Reasoner replayed the tape from the beginning so the viewers could see Ruby shooting Oswald. Several minutes later, he reported that the Dallas Police had released Ruby's name. (Reasoner was not at the anchor desk when Oswald was declared dead since he had been replaced by Cronkite.)

input: In print, The Shadow's real name is Kent Allard, and he was a famed aviator who fought for the French during World War I. He became known by the alias the Black Eagle, according to The Shadow's Shadow (1933), although later stories revised this alias as the Dark Eagle, beginning with The Shadow Unmasks (1937). After the war, Allard finds a new challenge in waging war on criminals. Allard falsifies his death in the South American jungles, then returns to the United States. Arriving in New York City, he adopts numerous identities to conceal his existence.  One of the identities Allard assumes--indeed, the best known--is that of Lamont Cranston, a "wealthy young man-about-town." In the pulps, Cranston is a separate character; Allard frequently disguises himself as Cranston and adopts his identity (The Shadow Laughs, 1931). While Cranston travels the world, Allard assumes his identity in New York. In their first meeting, Allard, as The Shadow, threatens Cranston, saying he has arranged to switch signatures on various documents and other means that will allow him to take over the Lamont Cranston identity entirely unless Cranston agrees to allow Allard to impersonate him when he is abroad. Although alarmed at first, Cranston is amused by the irony of the situation and agrees. The two men sometimes meet in order to impersonate each other (Crime over Miami, 1940). The disguise works well because Allard and Cranston resemble each other (Dictator of Crime, 1941).  His other disguises include businessman Henry Arnaud, who first appeared in The Black Master (March 1, 1932), which revealed that like Cranston, there is a real Henry Arnaud; elderly Isaac Twambley, who first appeared in No Time For Murder; and Fritz, who first appeared in The Living Shadow (April 1931); in this last disguise, he sometimes takes the place of the doddering old slow-witted, uncommunicative janitor who works at Police Headquarters in order to listen in on conversations and to look at evidence.  For the first half of The Shadow's tenure in the pulps, his past and identity are ambiguous. In The Living Shadow, a thug claims to have seen the Shadow's face, and thought he saw "a piece of white that looked like a bandage." In The Black Master and The Shadow's Shadow, the villains both see The Shadow's true face and remark that The Shadow is a man of many faces with no face of his own. It was not until the August 1937 issue, The Shadow Unmasks, that The Shadow's real name is revealed.  In the radio drama, the Allard secret identity was dropped for simplicity's sake. On the radio, The Shadow was only Lamont Cranston; he had no other aliases or disguises.
