Born May 18, 1922 in Bergen, Norway, died December 29, 2005 in London) is the founder of Biodynamic Psychology, a branch of Body Psychotherapy.
Gerda Boyesen was born in 1922 in Bergen. Her first marriage was with Carl Boyesen. In 1947 she read a book by Wilhelm Reich which made a strong impression on her. Shortly thereafter she began therapy with Ola Raknes, a vegetotherapist who had been trained by Reich. Later she studied psychology in Oslo and received training as physiotherapist which led to work with Aadel Bülow-Hansen. Through her own therapy Boyesen got to know the connection between repressed emotions and muscle tensions, linking the beginnings of Wilhelm Reich, Carl Gustav Jung and Sigmund Freud.
Gerda Boyesen is the founder of "Biodynamics Psychology and Psychotherapy". In 1968 she left for London and opened a practice and later an international teaching and training institute. In addition to client-oriented work other focus areas were included, most notably she was the first woman in Europe to establish her own psychotherapeutic training institute.
Gerda Boyesen lived and worked in different, mostly European, countries, however, her work influenced body psychotherapy worldwide. Her books were translated into other languages. She trained psychotherapists over several decades and throughout her life she continued to develop her ideas and methods. She was the mother of three children (Mona Lisa, Ebba and Paul) who all got involved with Biodynamics and psychotherapy and partly carried on the work of their mother or continued in their own directions.
Gerda Boyesen developed, among other things, the theory that the dismantling of psychological stress is also connected with the digestive system. She came to the conclusion that certain massage techniques could bring to completion the expression of unwanted feelings, or "incomplete cycles," and this would entail similar noises from the intestines as during digestion of food. She called these noises psychoperistalsis. This process of "digesting" psychological problems is often accompanied by new insights. For this reason Gerda Boyesen was often called "the lady with the stethoscope" in body psychotherapeutic circles as she used the stethoscope to get a clearer impression of the bowel noises of her clients. She could allegedly differentiate a multiplicity of peristaltic noises, diagnostically arrange and make inferences on the subconscious processes of the clients. To Gerda Boyesen it was a good sign when the client's "psychoperistalsis" was in a particular way at the end of a session. That meant it was resolving somewhat and would be able to organize anew without the old restricitve pattern.
she also worked with Wilhelm Reich's vegetotherapy as well as the theories of Jung and Freud, and she continued to develop these into her own method. In this manner the client is to be encouraged to discover his or her own mental experience (introspective ability), to follow and to express his or her bodily-psychological impulses. Unconscious conflicts would in this way be brought to the surface and to conscious attention and could then be further processed with psychotherapy and finally resolved.

further element is the Deep Draining, a special kind of massage aimed at affecting "deeper layers," which is supposed to contribute to attitude changes, physically as well as psychologically. Neurotic patterns would thus be traced, loosened and finally resolved.
