Emma Kunz was a Swiss healer whose geometrical drawings, made with the assistance of a divining pendulum, make visible the forms of radiation emitted by the people with whom she worked. The 600 drawings she left were first presented to the public in 1973 in an exhibition at Aargauer Kunsthaus. Retrospectives at the Kunsthalle Düsseldorf and the Musée d’Art Moderne in Paris furthered her reputation as an artist, which was cemented when in 1999 she was included in Harald Szeemann’s Lyon Biennale and exhibited alongside Joseph Beuys and Rudolf Steiner at Kunsthalle Zurich. Her work has since been shown at venues including Drawing Center, New York; the Irish Museum of Modern Art, Dublin; Zentrum Paul Klee, Bern; the 55th Venice Biennale; and the 14th Shanghai Biennale.
