[4] Rosenbach returned to Germany and founded the School for Creative Feminism in Cologne.

In July 2007 she retired from the university and began working as a freelance artist in the Cologne-Bonn area and in the Saarland.

Having joined the German women’s movement in the late 1960s, she travelled internationally to participate in feminist performance activities in association with the Woman’s Building in Los Angeles in the 1970s.

Beginning to perform ritual actions in 1969, she experimented with using her body as a medium of expression and video as a recording and documenting device.

In her work, she probes “the patriarchal basis of art history, its mythological presentations of women, the damage such stereotypes cause to women’s identity and creativity, and the strength of women to constitute the forms of their own visual representations and identity.”[8] Having studied Buddhism and other esoteric topics, Rosenbach valued intellectual depth and was interested in exploring the psychic and spiritual dimensions of experience.
