In her book, Barbara Hoos de Jokisch presents the first comprehensive approach to the influential work and activities of Franziska Martienssen-Lohmann (1887-1971). Her ground-breaking publications on vocal theory and pedagogy are timeless with respect to their contents, and modern in their methodology. The author uses vivid language to illustrate the writings of the distinguished voice teacher from a contemporary-history perspective, as well as from a biographical and philosophical one. The multifaceted book and enclosed CD-ROM contain a large quantity of previously unpublished photos, correspondence and other source texts. Recommended reading for all singers, voice students, teachers, voice scholars and vocal scientists.
