Eugène Danguy was a photographer who became a professional lantern operator in the late 1870s and subsequently devised a unique method of creating dissolving views. Typically, three different slides representing a temporal progression—for example, from dawn to daylight to dusk—would be projected one by one through the separate lenses of a triple (stacked) magic lantern. Danguy’s invention allowed slides to be projected simultaneously, through lenses fitted with special optical systems and shutters. His performances, ranging in duration from twenty-five minutes to an hour, followed an “around the world” narrative that included spoken narration.
