セシル・ヘプワース
Hepworth was also one of the first to recognize the potential of film stars, both animal and human, with several recurring characters appearing in his films.
By 1910, Hepworth was also the inventor of Vivaphone, an early sound on disk system for adding sound to motion pictures. The device used phonograph records to record and play back the sound. Hepworth's Vivaphone was distributed in Britain and also in the United States and Canada.
The company continued making popular films into the 1920s, despite Hepworth's now unchanging and increasingly old-fashioned film style.
