Jungfrauen
The Jungfrauen, also called Carl Jung's valkyries or the maenads, were a supportive group of women analysts (mainly based in Zurich) who were among Jung's first interpreters. They were early popularisers of his ideas.
Central to the Jungfrauen were Toni Wolff, Jolande Jacobi, Marie-Louise von Franz, Barbara Hannah, Ester Harding, and Aniela Jaffé. Other, more peripheral, figures were Kristine Mann and Hilde Kirsch.
The German word Jungfrauen means virgins; in the present context, it is a pun. The adjective jung means "young" and the plural noun Frauen means "women".
