Here's a belated obit (on account of, I just found out) for Robert C. Bruce, who died August 24, 2003 at the age of 89. Mr. Bruce was a voice actor in many cartoons of the thirties, forties and fifties, most notably as the narrator of silly travelogues and newsreels. You know all those great Looney Tunes like Detouring America and Of Thee I Sting with a serious announcer who sounded like a real travelogue host? Well, that serious announcer was usually Robert C. Bruce. He was an announcer and actor on KFWB, a radio station then owned by Warner Brothers (note the "WB") and housed on the studio lot, not far from where they made Warner Brothers cartoons. He appeared on many shows for the station but the most famous was probably The Grouch Club, which also featured Arthur Q. Bryan, the voice of Elmer Fudd.
Bruce was heard on many radio shows and on what some call the earliest cartoon made for television. It was called NBC Comic Book and it consisted of several radio actors voicing what were very close to still drawings. Later, he had a company that produced TV shows that were not unlike real travelogues and newsreels. In the late sixties, he retired to a home in South Carolina.
Information on Mr. Bruce has generally been a bit elusive, in part because he has often been confused with his father, who had the same name. Robert C. Bruce Sr. was a cinematographer and still photographer whose work included some of the earliest silent travelogues, and he passed away in 1948. The Internet Movie Database has a page that confuses the two men to the extent of saying Robert C. Bruce died in '48 but kept on voicing cartoons until 1959.
That's about all I know about the man. But I sure know that voice and if you like great cartoons, so do you.
