The sources for Citizen Kane, the 1941 American motion picture that marked the feature film debut of Orson Welles, have been the subject of speculation and controversy since the project's inception. With a story spanning 60 years, the quasi-biographical film examines the life and legacy of Charles Foster Kane, played by Welles, a fictional character based in part upon the American newspaper magnate William Randolph Hearst and Chicago tycoons Samuel Insull and Harold McCormick. A rich incorporation of the experiences and knowledge of its authors, the film earned an Academy Award for Best Writing (Original Screenplay) for Herman J. Mankiewicz and Welles.

Charles Foster Kane

Orson Welles never confirmed a principal source for the character of Charles Foster Kane. John Houseman, who worked with screenwriter Herman J. Mankiewicz on the early draft scripts, wrote that Kane is a synthesis of different personalities, with Hearst's life used as the main source. "The truth is simple: for the basic concept of Charles Foster Kane and for the main lines and significant events of his public life, Mankiewicz used as his model the figure of William Randolph Hearst. To this were added incidents and details invented or derived from other sources." Houseman adds that they "grafted anecdotes from other giants of journalism, including Pulitzer, Northcliffe and Mank's first boss, Herbert Bayard Swope."

Welles said, "Mr. Hearst was quite a bit like Kane, although Kane isn't really founded on Hearst in particular, many people sat for it so to speak". He specifically acknowledged that aspects of Kane were drawn from the lives of two business tycoons familiar from his youth in Chicago — Samuel Insull and Harold Fowler McCormick.

William Randolph Hearst

The film is commonly regarded as a fictionalized, unrelentingly hostile parody of William Randolph Hearst, in spite of Welles's statement that "Citizen Kane is the story of a wholly fictitious character." Film historian Don Kilbourne has pointed out that much of the film's story is derived from aspects of Hearst's life that had already been published and that "some of Kane's speeches are almost verbatim copies of Hearst's. When Welles denied that the film was about the still-influential publisher, he did not convince many people."

The most identifiable anecdote from Hearst's life used in the film is his famous but almost certainly apocryphal exchange with illustrator Frederic Remington. In January 1897 Remington was sent to Cuba by Hearst's New York Journal, to provide illustrations to accompany Richard Harding Davis's reporting about an uprising against Spain's colonial rule. Remington purportedly cabled Hearst from Havana that he wished to return since everything was quiet and there would be no war. Hearst is supposed to have replied, "Please remain. You furnish the pictures, and I'll furnish the war". Although Hearst denied the truth of the now legendary story, a milestone of yellow journalism, the ensuing Spanish–American War has been called "Mr. Hearst's War".

Hearst biographer David Nasaw described Kane as "a cartoon-like caricature of a man who is hollowed out on the inside, forlorn, defeated, solitary because he cannot command the total obedience, loyalty, devotion, and love of those around him. Hearst, to the contrary, never regarded himself as a failure, never recognized defeat, never stopped loving Marion [Davies] or his wife. He did not, at the end of his life, run away from the world to entomb himself in a vast, gloomy art-choked hermitage."

Arguing for the release of Citizen Kane before the RKO board, Welles pointed out the irony that it was Hearst himself who had brought so much attention to the film being about him, and that Hearst columnist Louella Parsons was doing the most to publicize Kane's identification with Hearst. Public denials aside, Welles held the view that Hearst was a public figure and that the facts of a public figure's life were available for writers to reshape and restructure into works of fiction. Welles's legal advisor, Arnold Weissberger, put the issue in the form of a rhetorical question: "Will a man be allowed in effect to copyright the story of his life?"

Welles said that he had excised one scene from Mankiewicz's first draft that had certainly been based on Hearst. "In the original script we had a scene based on a notorious thing Hearst had done, which I still cannot repeat for publication. And I cut it out because I thought it hurt the film and wasn't in keeping with Kane's character. If I'd kept it in, I would have had no trouble with Hearst. He wouldn't have dared admit it was him.

In her 1971 essay, "Raising Kane", film critic Pauline Kael wrote that a vestige of this abandoned subplot survives in a remark made by Susan Alexander Kane to the reporter interviewing her: "Look, if you're smart, you'll get in touch with Raymond. He's the butler. You'll learn a lot from him. He knows where all the bodies are buried." Kael observed, "It's an odd, cryptic speech. In the first draft, Raymond literally knew where the bodies were buried: Mankiewicz had dished up a nasty version of the scandal sometimes referred to as the Strange Death of Thomas Ince." Referring to the suspicious 1924 death of the American film mogul after being a guest on Hearst's yacht, and noting that Kael's principal source was Houseman, film critic Jonathan Rosenbaum wrote that "it seems safe to conclude, even without her prodding, that some version of the story must have cropped up in Mankiewicz's first draft of the script, which Welles subsequently edited and added to."

One particular aspect of the character, Kane's profligate collecting of possessions, was directly taken from Hearst. "And it's very curious – a man who spends his entire life paying cash for objects he never looked at," Welles said. "He just acquired things, most of which were never opened, remained in boxes. It's really a quite accurate picture of Hearst to that extent." However Welles himself insisted that there were marked differences between his fictional creation and Hearst. Xanadu was modeled after Hearst’s large mansion Hearst Castle in San Simeon, California, which also had a private zoo and a large collection of art.

Samuel Insull

As a model for the makeup design of the old Charles Foster Kane, Welles gave Maurice Seiderman a photograph of Chicago industrialist Samuel Insull, with mustache.

A protégé of Thomas Edison, Insull was a man of humble origins who became the most powerful figure in the utilities field. He was married to a Broadway ingenue nearly 20 years his junior, spent a fortune trying to re-launch her career, and built the Chicago Civic Opera House.

In 1925, after a 26-year absence, Gladys Wallis Insull returned to the stage in a charity revival of The School for Scandal that ran two weeks in Chicago. When the performance was repeated on Broadway in October 1925, Herman Mankiewicz — then the third-string theater critic for The New York Times — was assigned to review the production. In an incident that became infamous, Mankiewicz returned to the press room drunk and wrote only the first sentence of a negative review before passing out on his typewriter. Mankiewicz resurrected the experience in writing the screenplay for Citizen Kane, incorporating it into the narrative of Jedediah Leland.

In 1926 Insull took a six-year lease on Chicago's Studebaker Theatre and financed a repertory company in which his wife starred. Gladys Insull's nerves broke when her company failed to find success, and the lease expired at the same time Insull's $4 billion financial empire collapsed in the Depression. Insull died in July 1938, bankrupt and disgraced.

Insull's life was also well known to Welles. Insull's publicity director John Clayton was a friend of Roger Hill, Welles's teacher at the Todd School and a lifelong friend.

Harold McCormick

Like Kane, Harold McCormick was divorced by his aristocratic first wife, Edith Rockefeller, and lavishly promoted the opera career of his only modestly talented second wife, Ganna Walska. In 1920 McCormick arranged for her to play the lead in a production of Zaza at the Chicago Opera. She fled the country after her Italian vocal instructor told her that she was unprepared to perform the night before the sold-out premiere.

Other sources Another member of the powerful McCormick family who inspired the character of Kane was Robert R. McCormick, the crusading publisher of the Chicago Tribune.

According to composer David Raksin, Bernard Herrmann used to say that much of Kane's story was based on McCormick, but that there was also a good deal of Welles in the flamboyant character.

Welles cited financier Basil Zaharoff as another inspiration for Kane. "I got the idea for the hidden-camera sequence in the Kane 'news digest' from a scene I did on March of Time in which Zaharoff, this great munitions-maker, was being moved around in his rose garden, just talking about the roses, in the last days before he died," Welles said. Film scholar Robert L. Carringer reviewed the December 3, 1936, script of the radio obituary in which Welles played Zaharoff, and found other similarities. In the opening scene, Zaharoff's secretaries are burning masses of secret papers in the enormous fireplace of his castle. A succession of witnesses testify about the tycoon's ruthless practices. "Finally, Zaharoff himself appears — an old man nearing death, alone except for his servants in the gigantic palace in Monte Carlo that he had acquired for his longtime mistress. His dying wish is to be wheeled out 'in the sun by that rosebush.'"

Jedediah Leland

In 1940, Welles invited longtime friend and Mercury Theatre colleague Joseph Cotten to join a small group for an initial read-through at Mankiewicz's house. Cotten wrote:

"I think I'll just listen," Welles said. "The title of this movie is Citizen Kane, and I play guess who." He turned to me. "Why don't you think of yourself as Jedediah Leland? His name, by the way, is a combination of Jed Harris and your agent, Leland Hayward." "There all resemblance ceases," Herman reassured me. These afternoon garden readings continued, and as the Mercury actors began arriving, the story started to breathe.

"I regard Leland with enormous affection," Welles told Bogdanovich, adding that the character of Jed Leland was based on drama critic Ashton Stevens, George Stevens's uncle and his own close boyhood friend. Regarded as the dean of American drama critics, Stevens began his journalism career in 1894 in San Francisco and started working for the Hearst newspapers three years later. In 1910 he moved to Chicago, where he covered the theater for 40 years and became a close friend of Dr. Maurice Bernstein, Welles's guardian. When Welles was a child Stevens used to tell him stories about Hearst, much like Leland tells Thompson about Kane in the film.

Welles said that he learned most of what he knew about the life of Hearst from Stevens. Welles sent Stevens an advance copy of the Citizen Kane script, and took him to the set during filming. "Later he saw the movie and thought the old man would be thrilled by it," said Welles. "Ashton was really one of the great ones. The last of the dandies — he worked for Hearst for some 50 years or so, and adored him. A gentleman … very much like Jed.

Mankiewicz incorporated an incident from his own early career as a theater critic into Leland. Mankiewicz was assigned to review the October 1925 opening of Gladys Wallis' production of The School for Scandal. After her opening-night performance in the role of Lady Teazle, Mankiewicz returned to the press room "… full of fury and too many drinks …", wrote biographer Richard Meryman:
