Jacob Levy Moreno (1889-1974) was a prodigiously creative individual whose self-assigned life mission was amelioration of the problems of human society. From an early age he was sensitive to injustice and inequality and believed that all people should have an opportunity for the fullest expression of their talents. As a teenage tutor of the children of wealthy Viennese bourgeois families, he encouraged his charges to give their toys to poor children who were not as fortunate as they. As a university student, Moreno, along with four chums, established the House of Encounter in Vienna, where they provided both shelter and assistance to poor people from all over the Austro-Hungarian Empire who were trying to emigrate to other countries. As a scientist, he became an inventor of methods through which he hoped to better the plight of marginalized, excluded, and disadvantaged groups of people as well as treat mental illness.
