The Dickson Experimental Sound Film
The Dickson Experimental Sound Film is a film made by William Dickson in late 1894 or early 1895. It is the first known film with live-recorded sound and appears to be the first motion picture made for the Kinetophone, the proto-sound-film system developed by Dickson and Thomas Edison.
