Friedrich (Frederick) Salomon Perls, better known as Fritz Perls, was a noted German-born psychiatrist and psychotherapist of Jewish descent.
Perls coined the term "Gestalt therapy" to identify the form of psychotherapy that he developed with his wife Laura Perls in the 1940s and 1950s. Perls became associated with the Esalen Institute in 1964, and he lived there until 1969. His approach to psychotherapy is related but not identical to Gestalt psychology, and it is different from Gestalt Theoretical Psychotherapy.
The core of the Gestalt Therapy process is enhanced awareness of sensation, perception, bodily feelings, emotion and behavior, in the present moment. Relationship is emphasized, along with contact between the self, its environment, and the other.
Perls has been widely cited outside the realm of psychotherapy for a quotation often described as the "Gestalt prayer." This was especially true in the 1960s, when the version of individualism it expresses was prevalent.
