Catherine Christer Hennix

Catherine Christer Hennix was a Swedish mathematician, composer, and visual artist known for her work in minimalist music, as well as her research in topology and mathematical logic. She was a key figure in the 1960s–70s avant-garde scene, collaborating with La Monte Young, Tony Conrad, and the Fluxus movement, creating drone-based compositions that explore extended duration, just intonation, and meditative sound structures. Hennix was affiliated with MIT’s AI Lab in the late 1970s and was later employed as a research professor of mathematics at SUNY New Paltz; she also worked with mathematician Alexander Esenin-Volpin.
