{{cite web}}: CS1 maint: url-status (link)Mr. Norton, 84, died of lung cancer Saturday, Jan. 25, in his Studio City, Calif., home. [..] Born in Chicago, Mr. Norton graduated from Sullivan High School in 1935. By the end of that decade, he was a disc jockey with a morning show on WAAF-AM 1000. He enlisted in the Army Air Forces during World War II and was a bombardier in the India-Burma-China war zone--a role he would claim made him the 'American record-holder for intake of quinine.' After the war, he became a regular on Chicago's radio scene and appeared on 'Captain Midnight,' 'Tom Mix' and 'Terry and the Pirates.' He met Garroway, an NBC staff announcer who would soon employ him as a regular on 'Garroway at Large,' a musical revue and talk show that moved to New York in 1952.
Mr. Hackett's career spanned more than half a century in nightclubs, movies, the stage and television. His rubbery face was a familiar one on America's home screens in the 1950s and 1960s when he was a frequent guest on talk shows hosted by Jack Paar and Arthur Godfrey.
