Gestalt therapy was developed by Frederick (Fritz) Perls, (1893–1970), a German psychoanalyst originally trained in the Freudian tradition; he left Germany in the 1930's for South Africa and emigrated to the United States in the immediate post-war years. Despite the publication of his book “Gestalt Therapy—Excitement and Growth in the Human Personality” (Perls, Hefferline and Goodman, 1950) his work remained relatively little known until Gestalt Therapy was taken up enthusiastically by the growth movement in the early 1960's. Although it is widely regarded as an established therapy in the United States, Gestalt remains relatively little known in the United Kingdom and there are probably few psychiatrists who are familiar with its theory and techniques. This paper is intended to present an introduction to Gestalt Therapy together with some idea of its application in clinical psychiatric practice.
