1853 __ Lantern Wheel of Light
Baron Franz von Uchatius (1811-1881)
Comment : The original version of his Lantern Wheel of Light is built using an oil lamp replacing the candle. This device contained a glass disk with an opaque shutter. The thin-slitted shutter however did not allow for a strong throw. This particular invention was created at the request of a commanding officer that wanted his troops to be trained using a 'teaching aid'. Using a kerosene lamp to replace his original candle, Uchatius built this with a glass disk full of sequence drawings , two lenses and a crank. When turned, the disk would revolve, as did the images thereby throwing a series of pictures on the wall and the subsequent 'motion' with it. These images however were cast upon the screen at approximately six inches square and were therefore too small to be effective. Uchatius would work on perfecting this device and in 1853 had an improved version.Baron Franz von Uchatius combines a disc of the phenakistiscope type with a magic lantern to project moving images. Uchatius, an Austrian army lieutenant who sees his invention as a military teaching aid, demonstrates his device, which he calls the Lantern Wheel of Light, to the Viennese Academy of Science. Uchatius reverted back to his original idea of nineteen years earlier. He rotated the light source as opposed to the images. Using a crank and upgrading once again the illumination, this time to limelight, Uchatius cranked picture after picture, giving a strong impression of movement. A lens was positioned in front of each drawing on the disk and as the disk was revolved, the light moved with the image. This was how he originally had envisioned his device to work (moving his light source behind each drawing instead of moving the images). As opposed to the Fantoscope and Stroboscope, Uchatius’s machine could entertain many at one time which is what it was meant to do as a military teaching instrument. There is some question as to whether or not Ludwig Dobler, a Vienese purchased the 1845 or 1853 model. As a magician, Dobler traveled Europe giving 'motion picture' shows. (Paul T. Burns, ‘The History of the Discovery of Cinematography”)
French comment : En 1853, un autrichien, Franz Von Uchatius associe le phénakistiscope avec la lanterne magique et met au point le kinesticope : des images peintes sur un disque en rotation sont projetées, l'illusion du mouvement prend forme sur un écran. Partant de la « chambre noire » déjà connue de Léonard de Vinci, utilisant la propriété de certains sels minéraux de noircir à la lumière, un Français, Nicéphore Niepce, avait inventé la photographie en 1816. Vers 1851-52, l’opticien français Jules Duboscq présente à Londres le « stéréofantascope » qui substitue aux dessins du « phénakistiscope », des photographies obtenues par le procédé des poses successives, réunissant ainsi deux des voies qui mèneront au cinéma. Parallèlement, la chambre noire a, depuis le XVIIème siècle, donné naissance à « la lanterne magique », appareil qui permet de projeter des images lumineuses dans l’obscurité. En appliquant le « phénakistiscope » à la lanterne magique, l’Autrichien von Uchatius (1853) puis l’opticien français Jules Dubosq, réalisent pour la première fois la projection animée de dessins. Stroboscopie et projection font ainsi leur jonction. Mais il ne s’agit toujours – dessins ou poses successives – que de mouvements décomposés arbitrairement et non scientifiquement. Il faudra, pour parvenir à une analyse scientifique du mouvement – et donc à une synthèse réelle -, la diminution du temps de pose photographique jusqu’à l’instantané et à la prise de vues rapide qui permettront de saisir un sujet en action sans interrompre son mouvement.
