NLP was developed by John Grinder who had a background in linguistics and Richard Bandler whose background was in mathematics and gestalt therapy. Their focus was centered upon making explicit models of human excellence. Their first work, The Structure of Magic Vol. 1& II, identified the verbal and behavioral patterns of therapists Fritz Perls (the creator of gestalt therapy) and Virginia Satir (a renowned family therapist). Bandler and Grinder’s next work Patterns of the Hypnotic Techniques of Milton H. Erickson, M.D. Vol. I & II examined the verbal and behavioral patterns of Milton Erickson, founder of the American Society of Clinical Hypnotists, and one of the most widely acknowledged clinical psychiatrists of the 20th century. As a result of this work, Grinder and Bandler formalized their modeling techniques and their own individual contributions under the name Neuro-Linguistic Programming; symbolizing the relationship between the brain, language and the body. The basics of this model has been described in a series of books such as:Frogs Into Princes, Neuro-linguistic Programming Vol. I, Reframing, and Using Your Brain For a Change.
