On 5 February 1870, Philadelphia engineer Henry Renno Heyl presented three moving picture scenes with his Phasmatrope to 1500 persons at a church entertainment evening at the Philadelphia Academy of Music. Each scene was projected from its own a intermittent spur geared rotating disk with 16 photographic images. The only known extant disk repeated four images of a waltzing couple four times and was played with appropriate musical accompaniment of a 40-person orchestra. A disk depicting a Brother Jonathan speech was voiced live by an actor, and the other disc showed a jumping Japanese acrobat. Heyl's only known other show was a screening on 16 March 1870 at the Franklin Institute.
