A research chemist in wartime New York
Ida Rolf was born in New York in 1896, took her doctorate from Columbia in 1916, and walked into the Rockefeller Institute as a young woman because the First World War had hollowed out the male research workforce. She named this circumstance plainly when Don Hanlon Johnson interviewed her in 1974: a European war withdrew the young men, the institutes started hiring women, and she got her start through what she called, with characteristic frankness, a piece of good luck. The framing matters. Rolf did not enter science through advocacy or through a slow rise; she entered through an accident of demographics, and she understood for the rest of her life that her career rested on a door that had briefly opened. The Rockefeller hire would shape everything that followed — not because of any particular project she completed there, but because of the intellectual habits the laboratory instilled.
"I had what was for me and for a lot of women at that time, a piece of good luck. Namely, there was a European war. Yeah. And all of the young men were either in Europe or were being trained to go to Europe and were being withdrawn from their young men's positions in the industry and and in research and so forth. And those that hadn't been withdrawn, their employers were afraid they will be withdrawn, so they weren't hiring them and they started hiring women. And actually, I don't know how many of those of us women who got our starts through this accident appreciate the fact that for us that war was a great blessing. It gave us the opportunity to go out in the world and show that we could take the place of many of these people who had been withdrawn, many of these young men. Where was the first place place that you were employed then? I was employed at the by the Rockefeller Institute who also had seen the signs that their young men, their young staff you were being withdrawn for war service."
From the 1974 Structure Lectures, Rolf describes how she came to Rockefeller:
The Rockefeller Institute in those years was the most prestigious biomedical research institution in the United States, founded by John D. Rockefeller in 1901 to bring continental European laboratory science to America. Its researchers included Alexis Carrel, Peyton Rous, and the chemists Walter Jacobs and Michael Heidelberger — the latter two being the colleagues Rolf names as her direct supervisors. Heidelberger would go on to be celebrated as the founder of immunochemistry; Jacobs published widely on alkaloid chemistry. To be placed in their organic chemistry section was not a minor posting. The wartime project Rolf was assigned to was urgent and politically charged: the German pharmaceutical industry had produced an arsenic-based syphilis drug, Salvarsan and its successor Neosalvarsan, that worked. The American synthesis did not. The American product was poisoning patients.
"And I was one of the workers in a laboratory of the Rockefeller Institute where they were trying to solve the problem of solvusin and neo solvusin. The American product was proving very toxic. The German product was fine, but the German product was no longer available. And as Americans, they were trying to put an American solvusin on the market, and for some reason or another it persisted in being very toxic."
Rolf describes the specific Rockefeller project to Johnson:
Why the American Salvarsan was toxic
To understand what Rolf was actually working on, it helps to know what Salvarsan was. Paul Ehrlich's laboratory in Frankfurt had synthesized arsphenamine in 1909 as the first effective treatment for syphilis — the original 'magic bullet,' an arsenic compound that killed the spirochete without killing the patient. Neosalvarsan was its more soluble successor. Both were complex organoarsenic molecules whose therapeutic effect depended on a precise three-dimensional arrangement of atoms around the arsenic core. When American chemists tried to reverse-engineer the synthesis during the war, they could match the molecular formula but not reliably the molecular geometry. The result was a drug that nominally contained the right ingredients but whose atoms were arranged in subtly different patterns — and those small arrangement differences caused severe toxicity. This was the lesson Rolf absorbed in her twenties: that two chemical preparations could share an empirical formula and still behave as poison and remedy. Structure, not composition, determined function.
She would return to this principle for the rest of her life, often without naming Rockefeller as its source. In her advanced classes fifty years later, when she explained why the body is plastic, why collagen behaves the way it does, why graphite and diamond are the same atom in different arrangements, she was repeating a doctrine she had absorbed at the lab bench in 1917. Valerie Hunt, the UCLA kinesiologist who studied Rolf's work in the 1970s, picked up the same theme in her own lectures and made the chemistry-structure analogy explicit.
"And not that this isn't important we have to know properties of matter, but it didn't explain many of the phenomena that we know occur in the human body. It couldn't be explained by the materials of the body nor could it be explained by the systems of the body. And new insights have come from the arrangement of atoms and the arrangement of molecules and the patterning of functioning. And I speak about the patterning of functioning because that is what I concern myself with in my research. And this new kind of frame of reference then is eminently more difficult because there are so many relationships are possible, and what relationships do we discover? So in a sense, we don't set out to test the regular hypotheses that we have always used in our well structured scientific research, but we set out to find what is happening. It's an open end. It's exciting, but we don't know what's going to happen and some of the things which I'll report to you in the end happened as a result of this type of an open end research approach. To give you some of the examples of what this has meant is to relate to you that graphite and diamonds are of the same substance they are of carbon."
Hunt summarizes the same principle Rolf had absorbed at Rockefeller decades earlier:
Hunt's analogy — that diamond and graphite are the same atom in different arrangements — is the lay version of the Rockefeller problem. Ehrlich's German Salvarsan and the American imitation contained the same atoms in nearly the same ratios, but the spatial arrangement was wrong, and the biological behavior diverged catastrophically. Whether Rolf herself solved the Salvarsan toxicity problem during her years at Rockefeller is not clear from the transcripts; her account is brief and she does not claim credit. What she does claim is that she watched the problem and absorbed its lesson.
The PhD she took because it was easy
Rolf's doctoral degree was awarded by Columbia in 1916, but in her 1974 recollection she revises the conventional triumph-of-the-pioneer narrative with a piece of characteristic deflation. She did not pursue the PhD out of vocation. She took it because Rockefeller offered it on terms favorable to wartime conditions, and an MD would have required more years of work than she wanted to invest. The remark matters because it tells us something about Rolf's relationship to credentialing throughout her life: she respected hard knowledge but distrusted the social machinery that conferred legitimacy on it. She would later operate outside the medical credentialing system entirely, and her impatience with that system has clear roots in the youthful pragmatism on display in this passage.
"Tell me this, do you think that if you had become and I'm just alleging something at this late stage of the game, do you think it would have been an advantage to you to have been an MD? Well, I faced the question one time long ago while I was down at the institute, I could have gone in for an MD, but I didn't. I went in for a PhD and I'm free to confess I did it because it was easy. I mean, was offered a PhD for my work at the Rockville Institute, so I took it. Needless to say, this was during the war when everybody was interested in giving things away in order to get to stay with them and help them. And that's the way that happened. This was during that first war. And things were in pretty much of a turmoil."
Asked by Johnson whether an MD would have helped her later work, Rolf explains why she did not pursue one:
It is worth pausing on what the Rockefeller environment was actually like for a young woman with a fresh doctorate in 1916. Heidelberger and Jacobs were running an organic chemistry program that produced not only Salvarsan-related work but also the foundational papers on emetine, alkaloid chemistry, and what would become immunochemistry. The laboratory culture was European in style — long hours at the bench, careful synthesis, an obsession with purity of preparation. Rolf would have spent her days isolating intermediates, running crystallizations, taking melting points, comparing American batches to German reference samples. The work was tedious, exacting, and conceptually rich. She did it for several years.
The journey to Europe and the speculation on the train
In the late 1920s Rolf was sent to Europe by the Rockefeller Institute. The pretext was professional: to see what European laboratories were doing, to attend lectures, to keep American chemistry current with continental developments. She used the trip to attend lectures by Erwin Schrödinger and the physical chemist Peter Debye at Zurich. Schrödinger would publish his wave equation in 1926; Debye had already won the Nobel Prize for his work on dipole moments. Rolf was sitting in on lectures by two of the foundational figures of twentieth-century physical chemistry. She told Johnson that she learned less from Schrödinger directly than from Debye, but that Schrödinger taught her how to read the language of the physicists. It was somewhere on a train during this European trip that she had the thought that would, decades later, become structural integration.
"I don't know. I don't know, but I remember speculating as I was traveling on a train in Europe as to what was going to happen in terms of behavior if you change chemistry. I remember speculating on that. What was going to happen if you change chemistry? How would you change chemistry? The first way to change chemistry would be to change physics."
Asked by Johnson for the first seed-idea of what became her work, she answers:
The intellectual lineage here is worth tracing. Debye's work on dipole moments and X-ray crystallography was precisely about how the spatial arrangement of atoms in molecules determined their behavior in fields. Schrödinger's wave mechanics was a reframing of chemistry as a special case of physics — the chemistry of an atom, in the new view, was the consequence of its underlying physics. For a chemist who had spent a decade puzzling over why one arrangement of arsenic atoms healed and another arrangement poisoned, the new continental physics provided the deeper frame: chemistry was not the bottom of the explanation; physics was. The train ride was the moment Rolf saw how to apply that hierarchy to the body. If you wanted to change how a person behaved, you would not begin with chemistry. You would begin with physics — with the spatial arrangement of the parts.
"And I studied in Europe, but that wasn't my elementary study. My elementary studying was all here in The States. Well, know very little about the man Schrodinger? Schrodinger, yeah. Tell me what did you learn from Schrodinger? Schrodinger was a mathematician. And actually I probably learned less from Schrodinger than I did from Dubai who was a physicist. And what I learned from Schrodinger was how to understand the physicist of Bayes. I see. And Dubai was teaching at that time in Zurich, and I was on a leave of absence from the institute. And, you know, seeing that all cowboys have to go out and get steak dinners, Yeah."
Rolf describes what she learned from Schrödinger and Debye in Zurich:
Chemistry, then physics, then a body
The chain Rolf described on that train — physics modifies chemistry, chemistry modifies behavior — appears throughout her later teaching, often without acknowledgment of its origin. When she defined her work in the 1974 Healing Arts conference, she was explicit about the layer beneath chemistry. She defined the body as a plastic medium and grounded that plasticity in the chemistry of collagen, and grounded the chemistry of collagen in the physics of colloids. Each layer rests on the one below. This is exactly the hierarchy she had glimpsed on the European train forty years earlier.
"The mesodermal system of the embryo develops into bones and myofascia. All the tissues of the body which are collagen based derive from the embryonic mesoderm. And collagen has a unique characteristic. This is what makes Rolving possible. Like all body proteins, collagen is a colloid. It has a very high molecular weight. It is very complex. And it consists basically of three chains, protein chains, interlinked by mineral and hydrogen atoms. It is characteristic of all colloids that their physical state alters drastically by the addition of energy. You have experience of that right in the kitchen. You heat the colloidal aqueous suspension of jello, and it becomes clear what you think of as a solution, and it takes a chemist to see that it is a naceous sort of a thing that you realize, if you're a chemist, that it's not a true solution. It's a suspension. But at any rate, it flows, and it flows easily, And the chemist would say, it is in a sol state. And then you take it off the fire, and you put it into the refrigerator, and lo and behold, in very few minutes, you begin to get solids in the bottom. You begin to get a solid bottom, and presently it is solid throughout. And the chemist says, it is now in the gel state."
In her 1974 Open Universe lecture, Rolf explains the collagen-colloid chain that her chemistry training had given her:
The kitchen analogy is disarmingly simple, but the underlying claim is large. Rolf is asserting that human soft tissue obeys colloid chemistry — that fascia is governed by the same physics that governs jellies, gels, and protein suspensions. This is not metaphorical. She means it literally. Her authority for the claim comes from her years at Rockefeller, where she watched proteins move between sol and gel states daily at the bench. The body, in her view, is a chemistry laboratory whose colloids happen to be arranged in a particular three-dimensional pattern. Disorder that pattern and the colloids stiffen; add energy in the right direction and they re-fluidize. The whole doctrine of plasticity is colloid chemistry applied to a human shape.
"Collagen is a colloid and as are all large molecules of protein molecules of protein. Colloids have certain qualities in common. An outstanding one is that by the addition of energy, they become more fluid, more resilient. You remember that half set pan of gelatin in water? And water, it's gelled. You set it back on the stove, you turn up the light, and lo and behold, it liquefies. You take it off the stove, you set it in the fridge, and lo and behold, it solidifies. These this is a generalized quality of colloids and it is a generalized quality of the connected connective tissue of the body. Add energy to it and it becomes more fluid, more sol. Subtract energy and it becomes more dense, more solid, a gel. And as I said before, what do we mean by energy? In the case of the jello, we're talking about heat. In the case of the body, we may be talking about heat. Remember how different your flesh feels to your fingers in the very hot weather?"
Rolf restates the colloid principle and applies it to the practitioner's pressure:
Disorder, gravity, and the body's chemistry
Johnson, who had a philosopher's instinct for connecting Rolf's doctrines to broader scientific frameworks, asked her in the 1974 interview whether the law of entropy fit into her conception. The question seems to have caught Rolf off guard — she said she had to think about it. But after a moment of hesitation, she gave an answer that revealed how thoroughly her chemistry training had become second nature to her: she did not need physics or thermodynamics to know that a disordered body, carried in a way it was never designed for, would fail to function. The Rockefeller experiment had been about exactly this — a slightly disordered molecule fails to perform as the well-ordered molecule does. The body was simply the molecule writ large.
"I don't see how anybody with eyes on their heads can expect that a very disordered body carried in a fashion which it never was designed for can fail to be disorganized and not be able to perform as it was designed to perform."
Pressed by Johnson on the entropy framing, Rolf gives her own version:
There is a particular intellectual move happening here that is worth naming. Rolf is treating the body as a chemical system whose macroscopic behavior — pain, fatigue, irritability — reflects the microscopic disorder of its protein architecture. This is not a vague analogy. She means that the same principle that made one batch of Salvarsan toxic and another therapeutic governs why one person feels well and another feels ill. The atoms are in different arrangements. In the drug, the rearrangement happens during synthesis; in the body, it happens through injury, accident, habit, gravity. The intervention is the same in both cases: rearrange the structure, recover the function.
"You understand that gravity is, biologically at least, gravity is accepted as a positive force by living bodies. Is that As a positive force in As a positive thing to be used if the body is in structural alignment. Oh, I think there's no question about that, and I think that we show the evidence of this day by day in our work. This happens over and over and over and over again. People come back to us and say, I don't know what you did to me last year. I can't last time. I can't imagine what you did to me. I feel so much better. I sleep so much better. I behave so much better, I'm so much more calm, I'm more tolerant. What on earth did you do to me? We haven't done a thing except to make them make it possible for them to live in a friendly instead of an unfriendly environment."
Continuing her response to Johnson, Rolf describes what happens when the disorder is corrected:
Spirals and the arrangement of matter
The other figure who lectured alongside Rolf in 1974, Valerie Hunt, brought her own reading of the structure-determines-function principle and extended it to DNA. The choice of example was telling. Hunt was lecturing in the same room as Rolf, in front of the same students, and her examples — graphite versus diamond, sulfa drugs working by molecular mimicry, the helix of DNA encoding inheritance — were all variations on Rolf's Rockefeller theme. Hunt understood that the principle Rolf had derived from arsenic chemotherapy in 1917 was the same principle that twentieth-century molecular biology was discovering in DNA fifty years later.
"Sulfur drugs that we are all quite familiar with work, and they work basically because they simulate the arrangement of the substances of the human body the arrangement of the atoms. And as a result, bacteria misplaces the atoms of the sulfa drug for that of the human body and it is devoured. I think the most dramatic focus that we have on this type of approach comes from understanding the molecular structure of genetic mechanism of life And the spiral structure of DNA I'm talking frequently about spirals. On Wednesday I'll talk more about spirals, about the shape and the arrangement of materials. But the spiral structure of the DNA carries the ability to reproduce itself. It is not the basic elements it is the structure of it. And it carries also the program for growth and for development of the unfolding human organism or living tissue. Well, that's all I'm going to say about the century and about an approach to research, except to say that structure is not a thing in space. It cannot really be defined specifically as a thing in space. Rather, it is a series of ordered relationships, and those ordered relationships constitute the area of my particular study."
Hunt extends the structure-function principle to DNA and to the patterning of human energy:
What is striking about the Rolf-Hunt parallel is that two researchers from entirely different disciplines — one a chemist trained in 1916, the other a kinesiologist trained in the 1960s — converged on the same conviction: that the meaningful unit of biological study is not the substance but the arrangement of the substance. For Rolf this conviction came out of arsenic chemotherapy; for Hunt it came out of electromyography and information theory. The fact that they could lecture together at the same conference and reach the same conclusion from different starting points is itself evidence of how deep the principle ran in twentieth-century science. Rolf was an early observer of a shift that had not yet been named.
From chemotherapy to mechanical intervention
Rolf's later doctrine made an unusual decision about which kind of intervention belonged at the foundation of healing work. The dominant therapeutic tradition of her century was chemical — the medical school in which she had trained operated through pharmacology, and the Rockefeller Institute itself was largely a chemotherapy enterprise. Yet Rolf, having spent her formative years inside chemotherapy, walked away from it as her primary therapeutic mode. She did not reject chemistry; she retained its principles. But she chose pressure rather than pharmacology as her mechanism. The reasoning is implicit in her 1973 Big Sur lectures: chemistry, she says, came to dominate medicine because it provided a workable grammar a hundred and twenty-five years ago. But the deeper framework — structure determining function — could be approached more directly through mechanical means.
"Is a very basic consideration which I just offered you. It is the basic consideration that makes all manipulative techniques something to be considered. You see, our dominant school of healing is not manipulation, as you all know. It's medicine. It works through chemistry. And the reason this is so is because the chemical school of healing came to its own about one hundred and twenty five years ago. I'm not going into this at this moment, but I will discuss it at some later date with you people. The chemical school came in and everybody was so enamored of it that it spread out in all kinds of directions. The mechanical school of healing that I'm talking about, the structural school went out at that time. It had been in for several thousand years, I don't doubt."
In her 1973 Big Sur advanced class, Rolf situates her work in the history of healing modalities:
There is an autobiographical irony in this choice that Rolf herself never quite articulated but seems to have felt. She had worked, at the start of her career, on the most celebrated chemotherapy of the early twentieth century — the drug that finally made syphilis treatable and that Paul Ehrlich had called the magic bullet. She had watched, at the bench, how small structural variations made the difference between cure and poison. And the conclusion she drew from that experience was not that chemotherapy was the path forward, but that structure was the deeper principle, and that structure could be changed mechanically with less risk than it could be changed chemically. The American Salvarsan, after all, had killed people. Pressure on collagen would not.
The chemistry of collagen bonds
If the Rockefeller years gave Rolf a vocabulary for proteins as three-dimensional structures held together by specific bonds, that vocabulary stayed with her into the small-group teaching of her last decade. In a 1975 Boulder advanced class, a student asked her about the chemistry of arthritis and aging tissue. Rolf's answer was unmistakably a chemist's answer — she went straight to the atoms holding the collagen ladder together, named which atoms appear at which life stages, and noted that the substitution of hydrogen for calcium in those bonds is what one is actually working with at the molecular level. The transcript shows her cautioning the student that this is speculation without published data, but the framework is solid and laboratory-shaped: she was still thinking like a Rockefeller chemist about why young tissue is supple and old tissue is rigid.
"means? Yeah. Yeah. I think ten days or less. It's very simple. I mean, as you know, those collagen molecules have three strands going up, and the strands are like are held together like the rungs of a ladder. And in the middle of the rung is an atomic is an atom. Now what atom is it? Because if you get somebody who has a bad arthritis, for instance, you get a very heavy calcium. On the other hand, in the young, you get more hydrogen, etcetera, etcetera. And this is part of the difference. Now the chemistry of that body is determined by something else. And so you get a whole family of people who tend to arthritis, where they'll have a higher percentage of these higher valent atoms, these higher molecular connected. And that changes throughout the whole body too. Like, the biological age in the leg may be different than the biological age of the arm."
Asked about the chemistry of collagen, Rolf names the bonds directly:
What is unusual about this answer is the level of chemical specificity Rolf brings to a practical question about hands-on work. Most teachers of manual work explain stiffness in functional terms — short muscles, restricted joints, scar tissue. Rolf explains it at the level of which mineral atom occupies the cross-link in a triple-helical protein. This is not bedside chemistry. It is laboratory chemistry, brought to the body. And she is honest about its limits: she repeatedly tells the students that the specific story she is telling about calcium-for-hydrogen substitution is unpublished, that it is speculation, that there is no data. The intellectual habit of distinguishing what has been demonstrated from what has not been demonstrated is itself a Rockefeller habit.
The bench, the orange, the body
There is one more piece of evidence that Rolf's Rockefeller years stayed with her — the persistence of laboratory-style explanation in her teaching. When she described fascia to her students, she reached for a chemist's metaphor: an orange with its insides scooped out. The pulp is the chemistry; the rind is the structure; the structure is what gives the orange its shape, holds the chemistry in place, defines what the orange is. The same logic applies to a body. The metabolic processes — the chemistry — are housed inside a structural shell of fascia, and it is the structural shell, not the chemistry, that determines whether the body can function. This is the kind of metaphor a person makes only after years at a laboratory bench imagining proteins as physical objects with shapes.
"Visualize an orange as you cut it across through the equator. You have these cells, shown up by skin and inside the very soft tissue and sometimes little nuggets, nuts of flesh that are again in a skin. Those skins are what we call fascia, and they are they are purely collagen materials which derive from that original mild body that I was talking about earlier. We tend to think of them as muscles. Muscles is the soft stuff inside. Muscles is the stuff that makes the factory go, but fascia is the stuff that keeps it from falling in on itself, falling in on its face, keeps you from falling on your face."
Rolf reaches for a kitchen-and-chemistry image to teach what fascia is:
The orange metaphor would not occur to a clinician or a dancer or a yoga teacher. It is the metaphor of someone who has spent years thinking about protein structures at the laboratory bench — someone for whom the relationship between a molecule's pulp and its scaffold, its content and its arrangement, is the natural way to organize thought about matter. Fifty years after her Rockefeller hire, Rolf was still using the analytical habits the laboratory had given her. The chemotherapy project she worked on had ended; the doctrine it taught her had not.
What the Salvarsan years gave her
Taking the transcripts together, the Rockefeller and Salvarsan period gave Rolf five things that recur throughout her later teaching. First, the principle that structure determines function at every scale, from molecules to bodies. Second, the conviction that two arrangements of the same materials can produce opposite biological effects — that small structural differences cascade into large functional differences. Third, the priority of physics over chemistry as the deeper explanatory layer, a conviction she sealed during her Zurich months with Debye and Schrödinger. Fourth, the ability to think colloidally about soft tissue — to see fascia as a protein medium that can shift between sol and gel states under appropriate energy input. Fifth, a working knowledge of laboratory standards of evidence that would later distance her from the more speculative wings of the human-potential movement even as she remained engaged with them. The five together are the substrate of what became structural integration.
What the Rockefeller years did not give her was a method. The leap from understanding protein chemistry to deciding that one should press on a human body with one's hands required something the laboratory could not supply: a population of bodies on which to work, and a willingness to lay hands on them. That second phase of Rolf's life — the yoga group at Nyack with Pierre Bernard, the early experiments with one client at a time, the gradual emergence of a ten-session sequence — belongs to the 1930s and 1940s, not to Rockefeller. But the conceptual frame she brought to that second phase was Rockefeller-shaped. She was a chemist looking for the mechanical equivalent of a synthesis: an intervention that would rearrange the body's architecture in the way one rearranges a molecule, with the same precision, the same attention to spatial relationships, the same expectation that getting the arrangement right would change everything that flowed from it.
"From the imagine it would be in the thirties. In the thirties? I early thirties. Anyway At that point, Rolfing, is still not born. No, no, no, not even it wasn't a gleam in anybody's eyes. I'm going creep up on it. Did you say When did I get the idea rolfing? Did you help someone in some kind of I guess that yes. I guess that was the idea. Actually, I worked, and this was in the late thirties. I worked with I used to visit a weekly yoga group that worked up in Nyack, New York. It might be that some of you would have known that group. It was under Pierre Bernard. Bernard, yeah."
Asked by Johnson when her work was first born, Rolf identifies her starting point in the late 1930s:
Valerie Hunt, looking back from her own scientific career at how she found her way to studying the body, described a similar arc of discovery — moving through psychology, then physical therapy, then teaching massage during the polio epidemic, before finally arriving at a research program that could ask the questions she actually wanted to ask. The parallel is not exact. Hunt was a generation younger and trained in different disciplines. But the shape of the search — moving through institutional categories that did not quite fit, looking for the framework that would make sense of how bodies actually behave — recurs in both careers. Rolf had walked that road decades earlier.
"I decided I didn't have enough information, you see, that, well, I did a little teaching. I had to earn a little money. But, that wasn't important. And I decided that I didn't have enough information. So I had to go somewhere to get some more information. And so I decided, well, surely if I knew how man behaved and how he developed his personality, then I would have the answer to experience. I would know about the body. I would know about all of the open universe. And so I took a degree in psychology. And I found out about aberrations and rats and traits and personality. And the more I learned Aristotelian, I said, but there's no Gestalt except a in a philosophical sense. So I ended up with more knowledge and very little insight and back in the same place I was before. And so then I had another attack and I thought, well, I know the answer. I'll become a physical therapist. And if I understand healing and if I understand illness, then I can certainly understand the opposite of that, which is health and sanity and all of those things."
Hunt describes how she moved through psychology and physical therapy before finding her actual research question — an arc that rhymes with Rolf's own move from chemistry to the body:
Coda: the chemist who chose the hands
Ida Rolf was a research chemist before she was anything else. She trained at one of the most rigorous laboratories in the United States, under colleagues who would shape the chemistry of the next half-century. She worked on a real and consequential problem — why an American synthesis of a syphilis drug was poisoning patients when its German parent worked — and she walked away from that problem with a set of intellectual habits that never left her. The decision she made in middle age to leave the laboratory and work on bodies with her hands was not a rejection of her chemistry training. It was a specific application of it. She had concluded, on a train in Europe in her thirties, that if you wanted to change behavior you should change chemistry, and that if you wanted to change chemistry you should change physics. The body offered a place where physics could be changed directly — where the practitioner's hands could be the energy input that shifted a colloidal medium back toward its functional arrangement. The chemistry would follow. The behavior would follow. This was the doctrine, and it had Rockefeller fingerprints on every part of it.
