Danse serpentine (1897) by Lumière Brothers

Though both the dancer and cinematographer of this film are unknown, it was produced by the Lumières. Pictured is a dance style developed and popularised by Loïe (Marie Louise) Fuller (1862-1928), a dancer, choreographer, multimedia artist, and inventor. Fuller was perhaps the first modern dancer, and certainly the first from the USA to perform in Paris.

She was a huge sensation, becoming an integral part of the avant-garde, associated with the Art Nouveau, Symbolist, and Impressionist movements. Every major Parisian artist painted her.

Fuller invented stage under-lighting and received additional patents for light machines, costume design, and stage devices. She was made a member of the French Astronomical Society, started a school for dance, and founded two museums.

Her light shows, synchronised to music and coordinated with the dance, were famous. She refused to be filmed, because the visual quality at the time did not meet her exacting standards.
