One of Missouri’s radio pioneers has died at 83. Chuck Norman was best known for founding and owning St. Louis radio station WGNU-AM. Norman had been in ill health for several years and died of a heart attack in his penthouse on the 13th floor of a building in the 200 block of Union Boulevard, directly across the hall from the offices of the radio station. He remained the only sole-owner of a radio station in the St.Louis market. He had no immediate survivors and made arrangements to leave the station to WGNU employees. At one time he ran the Miss Missouri pageant from a television studio in St. Louis. Norman was inducted into the St. Louis Radio Hall of Fame in December of 2002.
