Simon Stockhausen is a German composer. His parents are the artist Mary Bauermeister and the composer Karlheinz Stockhausen; the musician Markus Stockhausen is his half-brother.

Mary Hildegard Ruth Bauermeister was a German artist who worked in sculpture, drawing, installation, performance, and music. Influenced by Fluxus artists and Nouveau Réalisme, her work addresses esoteric issues of how information is transferable through society. "I only followed an inner drive to express what was not yet there, in reality or thought", she said of her practice. "To make art was more a finding, searching process than a knowing." Beginning in the 1970s, her work concentrated on the themes surrounding New Age spirituality, specifically geomancy, the divine interpretation of lines on the ground.
