Larry D. Mann, best remembered for supplying the voice of Yukon Cornelius in the perennial animated holiday favorite Rudolph the Red-Nosed Reindeer, died on Monday in Los Angeles of age-related causes according to his son Richard, reports CBS News. He was 91.

Mann’s gruff but endearingly friendly voice of the robustly red-bearded Cornelius remains part of memorable set pieces among a sea of many in the special, as generations of fans fondly remember the character each annual airing. The special originally aired on NBC-TV during the 1965 Christmas Season and set the template for many of the stop-motion “Animagic” (the process of animating figures to create a seamless movement) specials to follow, mostly mired in Christmas themes.
