Moreno Institute East – Biographies:
New research out of the University of Vienna by Dr. Robert Waldl shows the enormous influence that Dr. Moreno’s theory of the Encounter (Invitations to an Encounter, 1914) had on the development of Martin Buber’s I-Thou philosophy, and Buber’s influence on philosophy, theology, and psychology. Dr. Moreno’s wife Zerka Moreno writes, “While it is true that Buber broadened the idea of the Encounter, he did not create the instruments for it to occur.” Moreno…produced the various instruments we now use for facilitating the human encounter, sociometry, group psychotherapy, psychodrama, and sociodrama” (Zerka Moreno, Psychodrama Network News, Winter 2007).
