Inventor Joseph Plateau did not give a name for the device when he first published about it in January 1833, but used 'phénakisticope' later that year in another article to refer to the published versions he was not involved with.
The spelling 'phenakistiscope' was possibly introduced by lithographers Forrester & Nichol in collaboration with optician John Dunn; they used the title "The Phenakistiscope, or, Magic Disc" for their box sets, as advertised in September 1833 [REF].
