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. His approach to psychotherapy is related to, but not identical to, Gestalt psychology, and it is different from Gestalt theoretical psychotherapy.

It has become a common feeling, I believe, as we have watched our heroes falling over the years, that our own small stone of activism, which might not seem to measure up to the rugged boulders of heroism we have so admired, is a paltry offering toward the building of an edifice of hope. Many who believe this choose to withhold their offerings out of shame. This is the tragedy of the world. For we can do nothing substantial toward changing our course on the planet, a destructive one, without rousing ourselves, individual by individual, and bringing our small, imperfect stones to the pile.
