Study Notes
Thomas Alva Edison and Innovation
- Recognized as a pioneering inventor, Edison contributed significantly to various technologies but did not invent the light bulb or phonograph alone.
- Established the first industrial research lab at Menlo Park, New Jersey, employing skilled assistants to facilitate innovation.
W.K.L. Dickson’s Contributions
- W.K.L. Dickson was tasked with animating photographs, aiming to create moving images similar to how phonographs produce sound.
- Developed the first motion picture camera and a peep-show style device, marking the birth of film production.
Kinetoscope Invention
- Edison filed preliminary patent claims for a coin-operated entertainment device called the "Kinetoscope," intended to pair images with audio from a phonograph.
- Aimed for the Kinetoscope to provide a unique viewing experience resembling an interactive movie theater.
Technical Challenges and Innovations
- Initial challenges included creating a camera to capture images and developing a durable film medium.
- Inspiration was drawn from Etienne-Jules Marey's chronophotographic gun, leading to the adaptation of this technology for motion capture.
Film Technology Development
- Dickson discovered that celluloid filmstrips coated in light-sensitive emulsion worked effectively for continuous playback, a standard still used today.
- Collaborated with George Eastman to produce celluloid film in 50 ft rolls, supplying the necessary materials for film production.
Film Projection Mechanism
- Developed a mechanism to intermittently stop and hold the film for exposure, enabling a clear sequence of images to be captured and projected.
- Introduced "sprocket holes" along film edges, facilitating the advancement of film during the projection process.
Kinetoscope Prototype Presentation
- In 1881, Edison revealed the Kinetoscope prototype at the National Federation of Women's Clubs in New York City, providing the first opportunity for public film viewing.
- The Kinetoscope, designed as a cabinet with a peep hole, enabled individuals to watch moving images, distinguishing it as an early film exhibition device.
Limitations of Edison’s Vision
- Edison's initial perspective limited motion pictures to be complementary to phonographs rather than seeing their standalone potential.
