Famous for one of the all-time classic bloopers; "Ladies and gentlemen, the president of the United States, Hoobert Heever."
He was awarded a Star on the Hollywood Walk of Fame for Radio at 6521 Hollywood Boulevard in Hollywood, California.
The huge blooper by Von Zell was not recorded at the time. It was recreated. Had Von Zell's mispronunciation occurred as the President was being introduced to an audience, it would have been highly embarrassing for the seasoned announcer. Von Zell's blooper occurred at the end of a brief presentation in honor of the President's birthday. While still embarrassing, it was not quite as mortifying as had President Hoover been in attendance.
