Detail of name plate. Robert W Paul (1869-1943) first demonstrated his Theatrograph projector at Finsbury Technical College, London, on 20 February 1896, the same day as the preview showing of the Lumiere Cinematographe in London. This projector is the second, improved model, patented on 2 March 1896, which went into production and was on sale for £80. With its intermittent motion provided by sprocket rollers driven by a Maltese Cros mechanism, this machine formed the prototype for the modern film projector.
