William Randolph Hearst (April 29, 1863 – August 14, 1951) was an American newspaper magnate and leading newspaper publisher. The son of self-made millionaire George Hearst, he became aware that his father received a northern California newspaper, The San Francisco Examiner, as payment of a gambling debt. Still a student at Harvard, he asked his father to give him the newspaper to run. In 1887, he became the paper's publisher and devoted long hours and much money to making it a success. Crusading for civic improvement and exposing municipal corruption, he greatly increased the paper's circulation.

Moving to New York City, he acquired The New York Journal and engaged in a bitter circulation war with Joseph Pulitzer's New York World which led to the creation of yellow journalism — sensationalized stories of dubious veracity. Acquiring more newspapers, Hearst created a chain that numbered nearly 30 papers in major American cities at its peak. He later expanded to magazines, creating the largest newspaper and magazine business in the world.

He was twice elected to the U.S. House of Representatives, but was defeated in 1906 in a race for governor of New York. Nonetheless, through his newspapers and magazines, he exercised enormous political influence, most notably in creating public frenzy which pushed the U.S. into war with Spain in 1898. His life story was a source of inspiration for the lead character in Orson Welles' classic film Citizen Kane.
