The Principles of Animation

The Principles of Animation "No one person or animator sat down and came up with the famous Twelve Principles of Animation, not even Walt. It was a collective effort through years of trial and error – analyzing when and why something read or worked better than something else. It wasn’t until 1981, 44 years after the first animated motion picture was released, that Frank Thomas and Ollie Johnston – two of Disney’s Nine Old Men – published The Illusion of Life and gave formal name to these principles."
