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.
I wished to make a motion picture which was not a narrative of action so much as an examination of character. For this, I desired a man of many sides and many aspects.
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.
