Name that group

[PoP]

Here's a little guessing game is to name that group. Name a list of people and you guess who that group is. Either music artists, sports groups, wrestling groups, working groups, war groups, etc. One hint will be permitted, unless you don't want to use a hint which is perfectly fine if you know the answer. If anyone didn't know the answer, I'll be kindly to answer and then anyone will give a shot of giving the next group for us to name the correct group.

I'll start as an example.

-Les Clark
-Marc Davis
-Ollie Johnston
-Milt Kahl
-Ward Kimball
-Eric Larson
-John Lounsbery
-Wolfgang Reitherman
-Frank Thomas

Hint: They worked for the iconic figure in animations

Who are they? Name That Group!
