Our next "You Know the Voice" subject is probably not quite as well known as many of his peers, but has chalked up quite the resume regardless.
George S. Irving made his fame on Broadway before being hired by Total Television in the 60's. His TTV credits include Go Go Gophers and, of course, narrating Underdog. After TTV folded, Irving landed the role of his career as the Heat Miser in Rankin-Bass' The Year Without a Santa Claus. He'd return for the sequel in 2008.
Irving passed away last year at 94, but what you might not know is that he also did some commercials that put him in front of the camera. His film & TV resume is rather small otherwise, particularly a guest shot on All in the Family and a supporting role in the short-lived The Dumplings.
In 1978, Irving was cast as a salesman who tried to get customers to try cheaper razor blades over Gillette's Trac II brand.
Irving also shilled for White Owl cigars, and maybe other sponsors, too. I'll have to take a closer look. At least some of you now have a face to match his voice.
