By 1950, the Animation Board—which had been established as early as 1940 to help with the management of the animation department—had settled down to nine supervising animators. Although they were still in their thirties, they were jokingly referred by Walt Disney as the "Nine Old Men" after President Franklin D. Roosevelt's denigration of the Supreme Court. Including Norman Ferguson, the principal animators included Les Clark, Marc Davis, Ollie Johnston, Milt Kahl, Ward Kimball, Eric Larson, John Lounsbery, Frank Thomas, and Wolfgang Reitherman.
