From The Lost Media Wiki
The Humpty Dumpty Circus was a stop-motion short from 1898 that was directed by J. Stuart Blackton and produced by Albert E. Smith. The short, known for being the earliest known example of stop-motion animation, used Smith's daughter's toys which were photographed scene by scene to create an illusion of constant movement.
