What a complete muddle these entries are! One reviewer believes the film to be watching Little Tich as "Miss Turpentine", his parody of Loie Fuller's Serpentine Dance, another believes himself to be watching Loie Fuller herself and a third thinks he's watching Ondine superimposed on a lion's cage.The Little Tich film does exist, Parodie d'une danse de Loie Fuller, and is a Gaumont films and dates from 1901. There is some doubt as to whether it is actually Harry Relph as advertised and may be a French impersonator who went by the name of "Little Pich".Loie Fuller, who created the famous dance in 1892, wrote her memoirs in 1908 and makes no mention of ever having appeared in a film. Basically she was too big a star to bother with the moving pictures. We can be pretty well certain therefore that there is no film which genuinely shows Loie Fuller dancing. The claim is most persistently made for the Lumière film (dated 1896 on IMDb but probably in fact made in 1899) but there is no evidence whatsoever for the claim.The trick film featuring "Ondine", probably by Alice Guy, dates seemingly from 1900 when such collation of two films by superimposition was all the rage.Which brings us to the question of Georges Demenÿ. Demenÿ had been an assistant to the physiologist Étienne-Jules Marey and was himself something of an expert in all that pertained to physical culture, so not unnaturally interested himself specially in films that were also studies in motion. One of the reasons for his rift with Marey had been his fondness for filming dancing girls and this may also have encouraged him to take up cinematography as a commercial proposition first of all (unsuccessfully) on his own and then (with moderate success for the brief time it lasted) in partnership with Léon Gaumont. Gaumont was more interested in the camera Demenÿ had invented than he was in Demenÿ himself and the two had fallen out by 1897. Gaumont simply appropriated the Demenÿ camera and a disgusted and ruined Demenÿ returned to his first love - physical education.There is record of a 58m film (Gaumont subsequently converted the Demenÿ camera to use standard 35mm film) of a Serpentine Dance (falsely ascribed to Loie Fuller), listed in Laurent Mannoni's biography of Demenÿ and this is very probably his work but where in the world it is now is goodness knows. The hand-coloured film on the internet that purports to be purports to be Demenÿ's film is in fact the Lumière film of c. 1899.
