From 1894 onwards the programme of the Grandsart-Courtoos theatre included a Serpentine dance act by Julie Grandsart, who was named after her grandmother, the reason why she probably chose ‘Miss Walter’ as a stage name and why many historians of magic confuse the two show women. Julie Grandsart must have been one of the earliest adepts of the American dancer Loïe Fuller, often referred to as the mother of modern dance. Fuller performed her famous dance for the first time in New York City in 1892 and brought it only one year later to Paris, where it caused a major sensation at the Folies-Bergère and, in subsequent years, attracted many imitators, such as Julie Grandsart. To what extent Miss Walter stayed true to her great example is still a question, but most probably the family used their lantern for her ‘Danse du Feu’ to project coloured light onto the swirling robe of the dancing Julie. It is indeed known that Fuller herself arranged mobile magic lanterns with circular gels containing various colours that shone on her from a variety of angles (Gunning 2003, 82).
