Friedrich (Frederick) Salomon Perls (July 8, 1893 – March 14, 1970), better known as Fritz Perls, was a noted German-born psychiatrist and psychotherapist. 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.
