 | | Demenÿ was Marey's assistant there, and the two researchers produced a considerable body of work, photographing human and animal movement using sequential photography, that is, chronophotography (a camera with fixed plate, and later moving plate, 1882-1888). |
 | | On 3 March 1892, Demenÿ filed a patent for the Phonoscope, an apparatus for glass discs (42 cm diameter) with a series of chronophotographic images on their circumference which could be projected using a powerful Molteni lantern. |
 | | After the Phonoscope was successfully presented at the Exposition Internationale de Photographie de Paris (1892), Demenÿ dreamed of commercialising chronophotography, and pushed Marey to order the manufacture of six cameras intended for sale. |
