Sound Work Under W. E. Systems
1925-26: Major development of the disk system of sound motion pictures, later trade-named "Vitaphone," was carried on by a group in the Bell Telephone Labs, headed by Dr. J. P. Maxfield. At about the same time, another group headed by Dr. Crandell and Dr. MacKenzie were working out a sound-on-film system using a "light valve" designed by Dr. Wente in the recording.
Apr. 20, 1926: Western Electric Co. entered into a contract with Warner Brothers and W. J. Rich, a financier, giving them an exclusive license for recording and reproducing sound pictures under the Western Electric system. The Vitaphone Co. was formed.
June 1926: The Vitaphone Co. opened a recording studio at the Old Manhattan Opera House, 34th St., New York.
Aug. 6, 1926: Warner Brothers gave their first public performance of Vitaphone at the Warner Theatre.

Dec. 31, 1926: Western Electric had equipped about twelve theatres with sound installations for Vitaphone.
