Le Lion Devenu Vieux (1932, 3.5MB, 1:04 sec.) Ladislas Starewitch is often credited with inventing stop motion animation as we know it, though so are several other people. It depends on what fits into your definition of stop motion. Certainly he was probably the first to actually make little figures and move them frame by frame in an attempt to duplicate lifelike movement of actual living things.
