 The Théâtre Optique patent of 1 December 1888 introduced the idea of film perforations.It has been suggested that Thomas Edison may have picked up this idea for the development of the Kinetoscope when he visited the Paris Exposition Universelle of 1889, where Reynaud won a bronze medal for all his works and purportedly exhibited his Théâtre Optique.According to Émile Reynaud's son, Auguste and Louis Lumière visited the "Pantomimes Lumineuses" and later were allowed to see the machine at Reynaud's workshop.
