Meanwhile, great figures in the world of medicine were recognizing the important relationship of the arts to healing. "Not I, but the poet discovered the unconscious," wrote Freud. Other theoreticians, such as Adler, Jung, Arieti and Reik also confirmed that the poets were the first to chart paths that science later followed. Moreno suggested the term "psychopoetry," as well as the term "psychodrama", for which he is famous. By the 1960's, with the progressive evolution of group psychotherapy, therapists were delighted to discover that "poetry therapy" was an effective tool which they felt comfortable incorporating into their work. Poetry Therapy began to flourish in the hands of professionals in various disciplines, including rehabilitation, education, library science, recreation, and the creative arts.
