Scientific career

Ida Pauline Rolf (May 19, 1896 – March 19, 1979[2]) was a biochemist and the creator of Structural Integration or "Rolfing".

Early life and education[edit]

Rolf was born in New York City in the Bronx on May 19, 1896. An only child, her father, Bernard Rolf, was a civil engineer who built docks and piers on the east coast.

Rolf graduated from Barnard College in 1916 with a bachelor's degree. She was in the Mathematics Club, German Club, Vice President of the class of 1916, a member of the Young Women's Christian Assn., was the alternate for the Graduate Fellowship while working at the Rockefeller Foundation, Business Manager of The Barnard Bulletin, and a member of Phi Beta Kappa. She received Departmental Honours in Chemistry at graduation. In 1917 she began her doctoral studies at Columbia University and, concurrently, Rolf also began work at the Rockefeller Institute as a chemical research worker. She was invited back to Barnard College in 1918 to speak to students about "work experiences".

In 1920, Rolf earned her PhD in biological chemistry under the supervision of Phoebus Aaron Theodore Levene, of Columbia University's College of Physicians and Surgeons. Her dissertation was entitled; "Three Contributions to the Chemistry of the Unsaturated Phosphatides", originally printed in three separate issues of "The Journal of Biological Chemistry", it was again printed in its entirety as a bound book in late 1922, "Phosphatides".

Throughout the decade, she was studying yoga and tantra with Pierre Bernard.


After graduating, Rolf continued to work with Levene at the Rockefeller Institute for Medical Research in New York City. In 1918 she was promoted to assistant in the chemistry lab.

In 1922, two years after having received her PhD from Columbia, Rolf was raised to associate, then the highest non-tenured position for a scientist at Rockefeller.[3]

From 1919 to 1927 she published 16 scholarly journal papers, mostly in the Journal of Biological Chemistry. Her research was primarily laboratory studies on biochemical compounds lecithin and cephalin. With the exception of her doctoral dissertation, all of her published work was co-authored with Levene.[3]

In 1926, Rolf left her academic work in New York, to study mathematics and atomic physics at the Swiss Federal Institute of Technology in Zurich and also biochemistry at the Pasteur Institute in France.[3]

Rolf later developed Structural Integration. In addition to her 16 academic papers published from 1919 to 1927, she would later publish two papers in scholarly journals on structural integration. She had an h-index of 10 with a total number of 299 citations (February, 2007).

Structural Integration (Rolfing)[edit]

Structural Integration (or Rolfing) is a type of manual therapy that aims to improve human biomechanical functioning as a whole rather than to treat particular symptoms.[4] Rolf began developing her system in the 1940s. Her main goal was to organize the human bodily structure in relation to gravity. Rolf called her method "Structural Integration", now also commonly known by the trademark "Rolfing".[5]

Structural integration is a pseudoscience and its claimed benefits are not substantiated by medical evidence.[6][7]

Rolf's second son, Richard, helped her to continue developing and refining Structural Integration, as well as assisting in preliminary studies of the healing effects of structural integration. They taught Structural Integration classes at locations around the United States from the 1960s thru the late 1970s. Auditor and practitioner classes were taught in California, Florida, and Glassboro NJ. Based for many years in New York City where they shared office and work space, they worked together to advance the practice and to make the general public aware of the practice and benefits of Structural Integration.[8]

In the mid-1960s she began teaching at Esalen Institute, where she created a loyal following of students and practitioners.[9] Esalen was the epicenter of the Human Potential Movement, allowing Rolf to exchange ideas with many contemporary visionaries, including Fritz Perls.[10][11]

In 1971, Rolf´s teaching activities were consolidated under the Rolf Institute of Structural Integration (RISI).[12][13] The school has been based in Boulder, Colorado since 1972. As of 2010, the RISI had graduated 1536 practitioners, including some trained in Germany, Brazil, Japan and Australia. In 1990, a group of senior RISI faculty split to found the Guild of Structural Integration, which had 628 graduates as of 2010. Currently there are nearly two dozen schools teaching Structural Integration.[14] Standards are maintained by a professional membership organization, the International Association of Structural Integration.[15]

In addition to the proliferation of practitioners and training institutes that are devoted specifically to Structural Integration, Rolf's concepts and methods have influenced a wide range of other contemporary manual therapies. A growing number of organizations offer training in "structural bodywork" or in techniques of fascial manipulation that are clearly derivative but lack the holistic perspective of Structural Integration, instead focusing only on the treatment of specific symptoms (i.e. massage therapists, chiropractors or physical therapists).[14][15]

Research foundation[edit]

In 2007, the Ida P. Rolf Fascia Research Foundation was formed to encourage and support evidence-based studies of Structural Integration's effects and its implications for conventional and complementary health care. It was introduced at the First International Fascia Research Congress (FRC) at the Harvard Medical Center. The foundation is dedicated to growing a symbiotic relationship between science and therapeutic practice. These events bring scientists and clinicians together to share their ideas and encourage collaboration.[16][17] The Fascia Research Congress occurred again in 2009 in Amsterdam, 2012 in Vancouver, BC, and in 2015 in Virginia, US.

Personal life[edit]

Ida Rolf was married to Walter Frederick Demmerle, an electrical and mechanical engineer who held patents for heating thermostats, and traveled abroad frequently with his work. They resided in Stony Brook, New York, and Manhasset, NY while raising a family. They had two sons, Alan Michael Demmerle and Richard Rolf Demmerle. Richard was a chiropractor and also a Rolfing instructor and practitioner who was involved in, and helped refine and develop his mother's Rolfing project and continued her work after Ida's death. Richard has three sons, Rolf Walter, Jean-Pierre, and Michael Richard. Richard moved to Switzerland in 1979 with Brigitte Waldmeier Demmerle, his wife, and their youngest son Michael Richard Demmerle. Rolf Walter resides in the US and is a custom builder, owner of "Demmerle Builders Inc." Jean-Pierre resides in Switzerland semi retired doing computer graphic design. Michael Richard still resides in Switzerland and owns a company doing media development, production and distribution. Richard Rolf Demmerle died February 1, 2015.[citation needed] Brigitte Waldmeier Demmerle passed in 2017.
