Caught in Moving Sand: The Films of Gisèle and Nag Ansorge

The Films of Gisèle and Nag Ansorge

  • Gisèle and Nag Ansorge

    Recognized worldwide for their work, pioneers of Swiss animation Gisèle Ansorge (1923-1993) and Ernest “Nag” Ansorge (1925-2013) originally trained as natural scientists (Gisèle was a pharmacist, and Ernest was a mechanical engineer). Fascinated by cinema and animation, they first used animation as a therapy to help patients with mental health issues. Inspired by the work of Jiří Trnka, they started experimenting with a Super 8 camera and puppets. They also used drawings and paper, but they are best known for developing sand animation, a technique that uses black quartz sand and stop-motion techniques to animate forms shaped with a paint brush. After testing several types of powders (including coffee, flour, and sugar), they chose quartz sand for its physical properties. Their first film using sand animation, The Raven (1967), premiered at the Annecy International Animation Film Festival and fascinated experts and audiences alike. Sand became the Ansorges’ hallmark. With Gisèle focused on shaping the sand, giving it meaning and style, and Ernest’s work on capturing the images and harnessing the technical aspects of filmmaking, the couple symbiotically created an outstanding body of works, including Fantasmatic (1969), Anima (1977), and Sabbath (1991), their last film before Gisèle passed away.

    Together they were also deeply committed to people in need. Through their work at a psychiatric clinic, the Ansorges helped long-term patients develop and realize their own cinematic ideas. Ernest was also involved with the charitable Emmaüs international organization, creating a community in Etagnières, his home village. Ernest also co-founded the Swiss Animator’s Group, or ASIFA Switzerland, in the late 1960s, an association that supports and advocates for animation professionals and film production.
