He served as president of Churchill Downs for nine years, and is widely credited for coining the term "Run for the Roses" to describe the Kentucky Derby.
Over the next 32 years, he filed nearly 10,000 columns with the Evening Journal and, following the merger of Hearst's morning and afternoon papers, the New York Journal-American, becoming one of the nation's most recognizable sports columnists and radio personalities.
Starting with the first Joe Louis-Billy Conn heavyweight title fight on June 18, 1941, Corum joined announcer Don Dunphy as ringside color commentator.
Along with Damon Runyon, Grantland Rice, Ring Lardner, Red Smith, Walter Winchell, John Drebinger, and Max Kase, Corum was a major player in sports radio and news in the 1930s, '40s and '50s.
Corum had called the Kentucky Derby on radio for most of the previous quarter century and had coined the term "Run for the Roses" in 1925.
