Innovations Necessary for the Advent of Cinema:



Innovations Necessary for the Advent of Cinema:
Optical toys, shadow shows, 'magic lanterns,' and visual tricks have existed for thousands of years. Many inventors, scientists, manufacturers and scientists have observed the visual phenomenon that a series of individual still pictures set into motion created the illusion of movement - a concept termed persistence of vision. This illusion of motion was first described by British physician Peter Mark Roget in 1824, and was a first step in the development of the cinema.
A number of technologies, simple optical toys and mechanical inventions related to motion and vision were developed in the early to late 19th century that were precursors to the birth of the motion picture industry:
  • [A very early version of a "magic lantern" was invented in the 17th century by Athanasius Kircher in Rome. It was a device with a lens that projected images from transparencies onto a screen, with a simple light source (such as a candle).]
  • 1824 - the invention of the Thaumatrope (the earliest version of an optical illusion toy that exploited the concept of "persistence of vision" first presented by Peter Mark Roget in a scholarly article) by an English doctor named Dr. John Ayrton Paris
  • 1831 - the discovery of the law of electromagnetic induction by English scientist Michael Faraday, a principle used in generating electricity and powering motors and other machines (including film equipment)
  • 1832 - the invention of the Fantascope (also called Phenakistiscope or "spindle viewer") by Belgian inventor Joseph Plateau, a device that simulated motion. A series or sequence of separate pictures depicting stages of an activity, such as juggling or dancing, were arranged around the perimeter or edges of a slotted disk. When the disk was placed before a mirror and spun or rotated, a spectator looking through the slots 'perceived' a moving picture.
  • 1834 - the invention and patenting of another stroboscopic device adaptation, the Daedalum (renamed the Zoetrope in 1867 by American William Lincoln) by British inventor William George Horner. It was a hollow, rotating drum/cylinder with a crank, with a strip of sequential photographs, drawings, paintings or illustrations on the interior surface and regularly spaced narrow slits through which a spectator observed the 'moving' drawings.
  • 1839 - the birth of still photography with the development of the first commercially-viable daguerreotype (a method of capturing still images on silvered, copper-metal plates) by French painter and inventor Louis-Jacques-Mande Daguerre
  • 1841 - the patenting of calotype (or Talbotype, a process for printing negative photographs on high-quality paper) by British inventor William Henry Fox Talbot
  • 1861 - the invention of the Kinematoscope, patented by Philadelphian Coleman Sellers, an improved rotating paddle machine to view (by hand-cranking) a series of stereoscopic still pictures on glass plates that were sequentially mounted in a cabinet-box
  • 1869 - the development of celluloid by John Wesley Hyatt, patented in 1870 and trademarked in 1873 - later used as the base for photographic film
  • 1870 - the first demonstration of the Phasmotrope (or Phasmatrope) by Henry Renno Heyl in Philadelphia, that showed a rapid succession of still or posed photographs of dancers, giving the illusion of motion
