Cahn lives and works in Stampa (Switzerland). She is one of the principal representatives of contemporary Swiss painting and a pioneer of the feminist movement in the 1970s; a demand made via drawings, Super 8 films, performances, photography, painting and, later on, writing. From 1968 to 1975 she studied engraving at the Kunstgewerbeschule, now the Schule für Gestaltung, in her native town. In 1982 she was invited to participate in the Documenta 7, in Kassel, but withdrew her work after disagreeing with the curatorial intervention. In spite of her outsider attitudes, the artist has been awarded the Käthe Kollwitz Prize (1998) and the Prix Meret Oppenheim (2005).
