Hephzibah is editor of the Melchisedec Press and the Halliday Review, both founded by David Mahlowe, Halliday’s first literary executor, to publish the work of Eugene Halliday. In 2015 she co-authored and published Personal Journey: John Zaradin in Conversation with Hephzibah Yohannan, a music memoir in which Zaradin describes meeting and working with Halliday. In 2017 she published The Paradoxical Ego by Eugene Halliday and Zhu Kabere; and Die Eroberung der Angst, a translation into German by Christian Handschug of Halliday’s The Conquest of Anxiety. These are published by the Melchisedec Press. In the Halliday Review she has written a short biography of Halliday and another of his friend the Jewish emigrée Käthe Schuftan, rediscovering an important but long-neglected artist. She is currently working on a full-length biography of Eugene Halliday.
