R.I.P. Arthur Rankin Jr.
 

Very Sad news and so close to the Time of Year that made him Famous... Rudolf The Red Nosed Reindeer, Santa Claus is Comin' to Town, Little Drummer Boy, Little Drummer Boy 2, Nestor the Long Eared Christmas Donkey, Life and Adventures of Santa Claus (a personal Favorite), Rudolf's Shiny New Year, The Year Without a Santa Claus, Rudolf and Frosty's Christmas in July, First Christmas Snow, Jack Frost, The Easter Bunny Is Comin' to Town, and Mad Monster Party.

and Leperchaun's Christmas Gold

and I did not know he was behind Thundercats

yeah he did a lot in the Animation world probably one of the Greats but gets overlooked. I'd put him up there with people like Walt Disney, Chuck Jones, William Hanna, or Joseph Barbera
