Dr. Finkelstein is a character and minor antagonist in Tim Burton's 1993 stop-motion Disney film The Nightmare Before Christmas. He is a wheelchair-bound mad scientist residing in Halloween Town, and the creator of Sally and Jewel Finkelstein. Throughout the film, he attempts to calm and restrain Sally against the outside world, while also helping Jack Skellington take Christmas. Too frustrated with his creation, Finkelstein abandons Sally and begins designing a new being, later revealed to be Jewel.
