Phonofilm is an optical sound-on-film system developed by inventors Lee de Forest and Theodore Case in the 1920s.
In 1919 and 1920, Lee De Forest, inventor of the audion tube, filed his first patents on a sound-on-film process, DeForest Phonofilm, which recorded sound directly onto film as parallel lines. These parallel lines photographically recorded electrical waveforms from a microphone, which were translated back into sound waves when the movie was projected. Some sources say that DeForest improved on the work of Finnish inventor Eric Tigerstedt — who was granted German patent 309.536 on 28 July 1914 for his sound-on-film work — and on the Tri-Ergon process, patented in 1919 by German inventors Josef Engl, Hans Vogt, and Joseph Massole.
The Phonofilm system, which recorded synchronized sound directly onto film, was used to record vaudeville acts, musical numbers, political speeches, and opera singers. The quality of Phonofilm was poor at first, improved somewhat in later years, but was never able to match the fidelity of sound-on-disc systems such as Vitaphone, or later sound-on-film systems such as RCA Photophone or Fox Movietone.
The name de Forest or De Forest may refer to:
Western Electric Company (WE, WECo) was an American electrical engineering and manufacturing company that served as the primary supplier to AT&T from 1881 to 1996. The company was responsible for many technological innovations and seminal developments in industrial management. It also served as the purchasing agent for the member companies of the Bell System.
In 1856, George Shawk purchased an electrical engineering business in Cleveland, Ohio. On December 31, 1869, he became partners with Enos M. Barton and, later the same year, sold his share to inventor Elisha Gray. In 1872 Barton and Gray moved the business to Clinton Street, Chicago, Illinois, and incorporated it as the Western Electric Manufacturing Company. They manufactured a variety of electrical products including typewriters, alarms, and lighting and had a close relationship with telegraph company Western Union, to whom they supplied relays and other equipment.
In 1875, Gray sold his interests to Western Union, including the caveat that he had filed against Alexander Graham Bell's patent application for the telephone. The ensuing legal battle between Western Union and the Bell Telephone Company over patent rights ended in 1879 with Western Union withdrawing from the telephone market and Bell acquiring Western Electric in 1881.
Warner Bros. Entertainment Inc. (commonly known as Warner Bros., Warners, or simply WB) is an American entertainment company that produces film, television and music entertainment. As one of the major film studios, it is a division of Time Warner, with its headquarters in Burbank, California. Warner Bros. has several subsidiary companies, including Warner Bros. Pictures, Warner Bros. Interactive Entertainment, Warner Bros. Television, Warner Bros. Animation, Warner Home Video, New Line Cinema, Castle Rock Entertainment, and DC Entertainment. Warner Bros. owns half of The CW Television Network.
The company's name originates from the four founding Warner brothers (born Wonskolaser or Wonsal before Anglicization):Harry (born Hirsz), Albert (born Aaron), Sam (born Szmul), and Jack (Itzhak, or to some sources, Jacob). They emigrated as small children with their parents to Canada from Krasnosielc which was located in the part of Congress Poland that had been subjugated to the Russian Empire following the eighteenth-century Partitions of Poland near present-day Ostrołęka.
