As early sound transcription and reproduction was dependant exclusively on acoustical or mechanical means by inserting a grid into the centre of a vacuum tube. With voltage directed to the grid and being able to control the flow of current across the tube. Lee De Forest had created a magnum opus that would benefit the entertainment establishment and habitats in every corner of the global sphere. Lee De Forest was plagued with misfortune throughout his life, but De Forest never wavered. You could say that he was blessed with the buoyancy of self-assurance and resolute determination. His visions were deeply focused on resolving what he envisaged as problems within the entertainment field of the film industry. With this in mind, he came up with the idea of an optical system and set about being the first to invent that type of system. By 1923 Lee De Forest developed a technique for transcribing sound waves into impulses of light, which could be photographed on a strip of film. This method enabled the developed film to pass between a light source and a photoelectric cell in the motion-picture projector. The images were transformed back into electrical voltages that could be converted into sound through a loudspeaker system. This idea was the forerunner of the Compact Disc (CD). With all of Le De Forest achievements: Biographers reported that Lee De Forest was tremendously concerned with seeking to attain acceptance from his peers all the way through his life, but alas, that was never to be. The only recognition he received was to be acknowledged as "the most liest boy in school." It is hard to believe that Lee De Forest was just a boy was classed as an ly boy by most biographers and script writers. De Forest must have been a very quiet lad. |
