who invented the photo-sensitive celluloid roll called film used in the kinetograph
Celluloid The first celluloid as a bulk material for forming objects was made in 1855 in Birmingham, England, by Alexander Parkes, who was never able to see his invention reach full fruition, after his firm went bankrupt due to scale-up costs.[3] Parkes patented his discovery after realising a solid residue remained after evaporation of the solvent from photographic collodion.
