from Edith, and before his second marriage, McCormick sought to fortify himself by undergoing an operation by Serge Voronoff, a surgeon who specialized in transplanting animal glands into aging men with impotency. In 1922, McCormick married Polish opera singer Ganna Walska. They divorced in 1931. McCormick died on October 16, 1941, of a cerebral hemorrhage, at his home in Beverly Hills, California. He was buried at Graceland Cemetery in Chicago. Legacy Orson Welles claimed that McCormick's lavish promotion of Walska's opera career—despite her renown as a terrible singer—was a direct influence on the screenplay for Citizen Kane, wherein the titular character does much the same for his second wife. Samuel Insull, president of a utilities holding empire that included Commonwealth Edison, was another influence, along with William Randolph Hearst.
