What is A113?

One imagines there are many secrets contained within the corridors of Disney. Was Walt really cryogenically frozen? Just who was responsible for ‘Treasure Planet’? How come Donald Duck doesn’t wear pants? One thing we do know the answer to is ‘What is A113?’

A113 (sometimes A-113 or A1-13) is an inside joke, an Easter egg in animated films created by alumni of California Institute of the Arts, referring to the classroom used by graphic design and character animation students including John Lasseter and Brad Bird.

Brad Bird first used it for a license plate number in the “Family Dog” episode of Amazing Stories. It has appeared in other Disney movies and every Pixar movie. Bird said, “I put it into every single one of my films, including my Simpsons episodes—it’s sort of my version of Hirschfeld’s ‘Nina.’

It can be seen in the following Television animation.

A113 may well be an inside joke, (probably the nerdiest ever) but it is also a tidy reminder of the sheer breadth of the influential talent that came from the California Institute of the Arts and how they came to shape a generation of filmmakers.
