William Sheldon (1898-1977) created an ingenious constitutional psychology based on a careful examination of normal bodily and temperamental differences which he expressed in terms of endomorphy, mesomorphy and ectomorphy.
This video explores his life and work. It takes us back to his boyhood in Rhode Island which holds the key to understanding his distinctive psychological approach, and the controversies that later surrounded him. We see Sheldon, himself, explaining his basic ideas, and visit his friends and colleagues: Louise Ames, who discusses some of the practical applications of Sheldon's psychology, Roland Elderkin, Emil Hartl, Ashton Tenney, Edward Humphreys, and Edward Monnelly, who gives a demonstration of Sheldon's final method of objectively determining somatotypes.

The words endomorph, mesomorph and ectomorph have entered into our language as ways to describe different kinds of human bodies, but we dont realize that they are the fragments of one of the greatest adventures in the history of American psychology and were coined by one of its giants, who less than twenty years after his death is almost completely forgotten.
Our story beings here in Pawtuxet, Rhode Island where William Sheldon was born in 1898 in a house that dated back to the 1740s. His grandmothers diary reads: "Saturday, November 19th Heavy rain. Will and Mame have a baby boy born at 25 minutes of six in the afternoon."
His mother and father came from old New England stock and though the family wealth was gone, their poverty did not weigh heavily upon them, for they could draw on a bounteous nature, a love of learning, and a sense of their place in the scheme of things.
Sheldon had an archetypal American boyhood. The family had a half acre garden of corn and tomatoes, carrots, peas and potatoes, and his father was an avid fisherman and hunter who supplemented his income by shooting game birds for market. Sheldon later called him "a lover of the wild and a reader of books," and watched him raise Irish setters and fine poultry. He was a shooting champion of national stature, and a founder of the Pawtuxet Gun Club. And little William grew up hunting rabbits and squirrels for the pot, gathering black walnuts and chestnuts, and fishing and claming.
Sheldon was on intimate terms with the inhabitants of the woods and marshes. He would play with the earth worms in his garden and look at the great moths who were a special love of his mother as almost part of the family. He would watch sympathetically and protectively as the great blue crab molted and entered into its vulnerable soft-shelled stage. It was a life attuned to the rhythms of nature, but for all that it did not lack a sense of culture and refinement, and a deep sense of belonging. There was his oldest brother Israel and his sister Kate, and his friends at the local school, and the world of the little village of Pawtuxet with its summer afternoon picnics, and the snows of winter. As a child of 5 or 6, during an excursion to the Boston Marathon, William had been taken by his Aunt Mary to visit her old friend, William James.
And all over the pre-revolutionary war homestead where he grew up he saw the evidence of where he had come from.
On the night of June 10th, 1772 Christopher Sheldon had joined 8 rowboats full of Providence men who made their way with muffled oars to his majestys ship Gaspee, sent to enforce the stamp act, and burned her.
Pardon Sheldon had commanded the ship Hanover out of Providence on a voyage through the Baltic Sea.
And his grandfather Israel Remington Sheldon had served as an officer in the war between the states. His commanding officer in the Rhode Island Artillery wrote commending him: "Campe near Falmouth, Virginia, February 7, 1863. Lieutenant Israel R. Sheldon has been engaged in many battles, always in command of a section, and by earnest endeavor through the whole time of his service fairly entitled himself to promotion."
Sheldons visual gifts and powers of observation were honed from his earliest years. He grew up in a world where observation was not a form of idle curiosity, but the means of putting food on the table or money in the pocket. It was a world where men prided themselves on their ability to shoot a duck flashing overhead, and to judge a fine hen or dog. And William took it for granted that it was possible for trained observers to come to virtually identical conclusions, for he saw it happen over and over again at dog and poultry and cattle shows. Sheldon became a fine shot and amateur ornithologist, and early on had a growing reputation as an appraiser of early American cents. All these things were to serve him well when he found his life work in trying to scientifically describe the differences among human bodies and temperaments and how the two were interrelated.
But the warmth of this New England world which was soon to be swallowed up in an increasingly urbanized America became his benchmark against which to measure his feelings for everything else, and most everything else failed to measure up. Later he would dream of the long winter evenings about the open fire when chores were done and there were chestnuts, apples and sweet potatoes for roasting, and the popping corn and parching corn and cider. "All these," he writes, "were part of the regular harvest of the countryside and so were taken for granted, like the logs in the fireplace and ones parents. There was one thing, however, which retained at all time such a halo of mystery and enchantment that it never came to be taken for granted. This was the cigar box of old copper cents which my father kept locked up in the grandfather sea chest On evenings when he was feeling especially well disposed, the kitchen lamp would be meticulously trimmed, the red kitchen tablecloth would be cleared of debris and brushed, and out would come the magnifying glass, four or five well-thumbed coin books, and the cigar box with the big cents."
Sheldon graduated from Warwick High School in 1915 and entered Brown University. With the American entrance into World War I he was commissioned a 2nd lieutenant in a machine gun company, and in 1919 received his degree in absentia. After the war he wandered westward, and it was sometime during these early years that Sheldon discovered the age-old riddle of the relationship between physique and temperament. He took a Ph.D. in psychology at the University of Chicago, writing a dissertation under the direction of L.L. Thurstone on the correlations between bodily measurements and mental traits.
In a series of studies Sheldon did, indeed, find a relationship, as others had done before him, but it was a small one and he could find no way to bring it out more strongly. He was 30 years old and had the makings of a good academic career. All he had to do was reconcile himself to the limits of the methods he was using. But he sensed there was a deeper dimension to this body and temperament riddle if only he could find a way to get at it. It was at this point that he made a fateful decision that was to bear enormously interesting results and embroil him in bitter controversy. What would happen, he asked himself, if he really looked at these bodily and temperamental differences? Could a carefully cultivated sense of clinical observation give him a way to break the impasse? Sheldon decided to fit himself for such an experiment by going to medical school and carefully studying the work of one of the worlds leading typologists, Ernst Kretschmer.
Sheldon took thousands of standardized photos of college men, but instead of letting measurement dominate the hunt, he scrutinized them, looking for basic factors that could be found in different degrees in all human bodies. Toward the end of his life he was interviewed on public television and described the basic elements that he discovered.
Dorothy Paschal: Dr. Sheldon, can you explain why we have to have a somatotype photograph?
Sheldon: Well, Ill try. A photograph is necessary if you want to really observe the proportions and shape of a structure and have that all before you, not just depend upon simple measurements. Actually, a human somatotype is really a way of describing he shape of a body Somatotype simply means body type, or the shape and form of the body. Now, if you really want to visualize the shape and form of something, a picture is a little better than words. It picks it up a little faster. So we base the whole early work of somatotyping on the process of photographing many thousands of different growing boys and girls, and college students and adults, and later in various patterns of physical variation as seen in medical school, in several hospitals where I have worked, and finally standardized the somatotyping procedure on the photographic process.
Dr. Paschal: Would you tell us a little bit about the first component and its derivation biologically speaking of endomorphy?
Dr. Sheldon: Ill try. There are, of course, three biological payers in a living organism. There is the inside basic layer which is called endomorphy, or lowest component, inside component. And then there is the middle layer of mesomorphy, or middle component, and then the outer layer called ectomorphy, which simply means outside. Thats all ecto means. Now from the endomorphy, called inside, component there develop the most vital organs of the body, at least the most fundamentally vital, namely the digestive tract, and the inside, or endomorphic part of any living body of any species is really that set of structures with which the individual of that species is digesting. And without digesting, it is a little difficult to live.
Dr. Paschal: Now how about the mesomorph?
Dr. Sheldon: The mesomorphic part of a living organism is the hard part. Its the middle part, that part which is strong and firm and hard. First, the skeletal system, of course, and then attached to the skeletal system, the muscles, and then attached to the muscles, all of the rest of the outside ectomorphic part of the body. So first you have the endo, the inner basic foundation of the body, and then the meso, the bone, muscle and connective tissue which holds everything together and gives it shape and form. Otherwise, you couldnt tell whether I am a buffalo or a bed but or a mud turtle, you see, but if you know the human structure and know what its meso looks like, you can look at a person and by standard measurements and by estimates, if you have had some experience, you can state what the degree of meso is. Not ecto is the higher and later elaboration of what originally had to have spread out from these inner layers. The ectomorphy is simply the outside surface of the body, and the outside surface of the body, of course, is developed into skin, and into the nervous system, including the brain, of course. If you didnt have any ecto you wouldnt have any brain, you see.
Dr. Paschal: Well, it looks like this on the chart stretched out, tall, usually, and lean.
Dr. Sheldon: Ectomorphs dont have to be tall, but with reference to their mass they have great surface. The surface area of an ectomorph is much greater with respect to his mass than that of a meso or an endo. An endo approaches spherical form.
Jim: Sheldon carried out a similar project to determine the basic factors of temperament, and found temperamental components corresponding to these basic elements of physique.
Louise Ames, the noted child psychologist, who later worked with Sheldon at Gesell Institute in New Haven (Connecticut) describes the practical use to which these temperament traits can be put.
Louise Ames: In relation to the parents questions, the parents who fret so: they have a child who cant get to sleep, the family is upset, they use disciplinary measures about the whole thing, the child is upset, and many parents apparently find it extremely useful to know that the child with an ectomorphic physique finds transitions difficult, for instance, from waking to sleeping, and from sleep to waking, and that such a child quite normally lies awake for an hour or more at night, and therefore if they appreciate that it is just the childs body, hes not being tiresome and bothersome, they are willing to provide a night light, if necessary, let a child road later than they think is desirable, or have music available, or even allow the child to play with a pet. And similarly, in the morning it bugs some of them that it is so hard to get the child out of bed, and they think he is just being resistant, but if they can understand that, just as some adults with an alarm clock need an extra ten minutes, I think that they are willing to plan to give the child extra warning in the morning. Thats one useful thing.
Parents of endomorphs dont seem to need much support from the Sheldon concepts. They are pleased to know that their child fits with what Sheldon says, but they dont seem to have that many problems. The parents of ectomorphs seem to have the most problems. Sleeping is a real problem. Eating is a real problem. The child, they will say on the phone, "My child doesnt eat enough to keep himself alive. He hasnt eaten anything for 3 or 4 weeks!" and in comes the parents with a good healthy, normal, skinny ectomorphic child. I think we have probably helped more ectomorphic children about eating than anything else. Weve tried to assure their parents they dont need three good solid meals a day. They dont necessarily need or want to eat a great deal.
Another place where many parents, especially as the children get older and into the teens, where parents find the Sheldon work useful is the friendship bit. They worry terribly if their children arent popular. I think parents worry a lot if their boys arent popular, and they worry even worse if their girls arent popular. If their girls arent popular, how are they ever going to get married and lead a normal life, they seem to think, and so if a teenage girl isnt popular, its very useful to explain to the parents that if she manages one good friend, she does real well, and that many ectomorphic children are comfortable at home by themselves, and so the parents dont add to the childs problem by a lot of nagging.
At any rate, I do think the ectomorph has the most problems, and has the most difficulty in just the ordinary things of life, and I think for parents to understand the appreciate that, it helps a lot of them to lay off. Especially often an ectomorphic child has at least one ectomorphic parent, and then when the parent clues in and say, "Thats exactly the way I was, but I didnt want him or her to have the same difficulty," you explain this child with the same body is going to have the same difficulties.
The other kind of child whom I think we can help, and I think parents are helped, by understanding Sheldon is the mesomorph. Just a week ago a little boy came in just over 6 years old, and the parents problem is he is so loud, and he is so noisy, and has so much trouble in school doing what the teacher says he should, he is so rebellious. We had the time to play down the fact that this very mesomorphic little boy may have lots of disciplinary problems in school, but at least I think the parents were helped to know that mesomorphy has its good side. Mesomorphs can be leaders and can be very, very effective in life, popular, and children like them, and especially when they get into athletics the school is going to appreciate them, but that they are going to be loud and noisy and aggressive, and that they do need acceptable outlets for this sort of thing. And when a mesomorphic child in kindergarten, first and second grade gets in trouble with the teacher, this is the time to realize he needs help rather than punishment. All of these things I find extremely interesting for parents, and it is a great regret to me that this kind of thing isnt spread around more and isnt more popular, and people dont talk about it.
Jim: Sheldon completed medical school, and went on a tour of Europe to visit the great psychologists, and then returned to Chicago to give a course. Roland Elderkin, one of his students, was so struck by his words that he was to devote many years to working with him.
Roland Elderkin: Well, the first time I ever heard of the man was in the fall of 1936 when I was in Chicago Theological Seminary. He taught a course called "Psychological Approach to Religion," and I took his course. He wasnt a person of physical accomplishments, but his wit was sparkling. Every meeting we had there was a sparkle of wit. Sheldon delighted in poking holes into the holy. He loved to tease and needle people in a rapier sort of way, not realizing most of the time they took it as an offense rather than something humorous.
Jim: From Chicago Sheldon moved on to Harvard where he gave some courses, and he soon met up again with Roland Elderkin and made a new friend in Emil Hartl who was running the Hayden Goodwill Inn for troubled boys.
Emil Hartl: I met him with Roland Elderkin when we looked him up because we learned he was across the river at Harvard University with Ernest Hooten. We were interested in looking him up because I was interested as the director of the Hayden Goodwill Inn School in securing him as our potential diagnostician in our clinical approach to working with our teenage boys. He agreed to give us quite a time, so he came Thursday evening, would immediately go up to his quarters, and we would have laid out for him all the clinical background of a given boy. We usually tried to have about three that he would see. There would be a clinical conference the next morning. He was already beginning to be, I would say, a celebrity in his field.
He had a high interest in adding the somatotypes in the clinical perspective, very creative and upbeat. There was enthusiasm on a wide basis. Life magazine had an article, a rather interesting one. Harpers magazine had an article. So these were Sheldons upbeat days.
Jim: Sheldon served in the Army in World War II and became seriously ill with a lymphatic cancer. After the war he moved to New York as director of Columbia Universitys Constitution Clinic, and it seemed like his daring gamble to mount a new attack on the problem of body and temperament was going to succeed. His work was spreading widely. It was taken up, for example, by the physical anthropologists C. Wesley and Helen Dupertuis who were to travel all over the world in their quest for a structural profile based on bodily measurements that could serve as a kind of morphological fingerprint and correlate with Sheldons somatotypes.
Their work, as well as Sheldons, benefited from the support and advice of Eugene McDermott, one of the founders of Texas Instruments. Ashton Tenney, a New York psychologist, recalls the years he worked with Sheldon and the impact Sheldon had made on him.
Ashton Tenney: Well, if we dont come to grips with the whole problem and question of human individual differences, we are really not going to get a handle on psychotherapy, on health, or any of these things, because everybody, in my opinion, like a snowflake, is different from everybody else, and he realized that everybody was different, but that there were certain limits that nature tolerates to allow a difference, and somebody has to come along and solve the problem of defining and describing and explaining and correlating the nature of individual differences with the very facts of life.
Well, back in the 60s and 70s there used to be a lot of talk about people wanting to find out who they were, "Who am I?", and when you raise that question, what are you talking about? Are you talking about who ma I culturally, who am I ethnically, or who am I physically, or who am I intellectually, and if you are going to get your act together, you better know who you are in a great variety of circumstances.
When I was a young man I would very much have liked to have been an athlete as thats what most young men appear to want to be. I would have liked to have gone to West Point. But I realized I was not a mesomorph, and no way could I reach that port of achievement. I had to find out who I was. The way I found out who I was was to become associated with William Sheldon. He gave me a lot of insight into what my potential and limitations were, and when I gave up what he would have called somatoerotic aspirations, well, then I could function a little bit better. I didnt try to be some big football player, or some big basketball player, and some other successful athlete.
I think in a certain sense Sheldon was interested in finding out who he was in terms of his career and what he did with his career because he looked like an adventurer who really explored his universe, and tried to come up with some answers as to who he was and what other people were, what his relationship was to the universe that he found himself in, and I admired what he was endeavoring to do, and felt that he gave me more understanding of myself than anybody else has ever done in my life, and I appreciated it.
Jim: Throughout these years Sheldon was preoccupied with the objections that were raised about his earlier work which claimed that his somatotyping was too subjective, and he devoted himself to the immensely complicated task of trying to find a completely objective way in which to determine a persons somatotype.
But these later years were a personal and professional turning point for him, as well. His health had been severely damaged during the war, and the criticisms of his earlier work rode the rising tide of a neo-Freudian environmentalism which had little sympathy with Sheldons biological approach. But Sheldon took all these things personally. He found himself more and more out of step with the hustle of a new urban America in the making, and his feelings, so much bound up with his New England boyhood, rebelled. He railed against city life and what he called urban wasters, and turned his sarcasm even against his coworkers and colleagues, the very people he needed so that his work would grow and have a future when he was gone. Dr. Edward Humphreys, a New Jersey psychiatrist, recalls the positive impact Sheldon could have on people.
Edward Humphreys: Well, I looked on him really as the king of the constitutionalists if you want to sum it up that way. At that time I felt he was a great man. There are certainly many people who disagreed with me on that point, but I still think he made a tremendous contribution to the field, and I think it is urgently in need for a restudy, a re-analysis, and development of new orientations so that the whole field is brought together in more explicit fashion.
Jim: In 1971 Sheldon moved to Scott St. in Cambridge, Massachusetts, just a few steps away from William James house, where he ended his life surrounded by some of his devoted friends like Dorothy Pascal and Edward Monnelly. Dr. Monnelly, now a staff psychiatrist for the Veterans Administration in Boston, and an expert on Sheldons psychology, was present during those last years.
Edward Monnelly: When I met Sheldon and had most of my contact with him was from 1973 on, and he would have been in his 70s living at Scott St. in Cambridge, he still kept very active with his projects. We worked with him fairly intensively several times a week on the follow-up of the book he had authored, Varieties of Delinquent Youth. We would review the materials that would come in on the 200 cases in that book, and updating the ratings that had been made in the first book. This was approximately a 30-year follow-up of some of these men. It was interesting to me how well Sheldon could, if you will, put his finger on what made these boys then, now men, tick, and some of the observations were very prognostic, and even prophetic, you might say. He would try to set up a procedure to be accurate and careful. He was not a quick or maybe even a sloppy worker in that regard, and I think many are. He didnt like to take short-cuts, and that, I think, has in a way held him back.
Jim: Ironically Sheldon finally did create an objective method of somatotyping, but it was unveiled to a world that by then was largely indifferent. Dr. Monnelly demonstrates how straight-forward it is.
Edward Monnelly: For many years the somatotype was criticized as being perhaps subjective, and even though Sheldon tried to develop tables to give some objectification to the somatotype, there was still this criticism, so he worked for many years on developing a set of indices that would function as an objective way of determining somatotype. The three indices that he came upon were maximal height, the so-called somatotyping ponderal index at maximal weight, and the trunk index. Now maximal height is very easy to determine. Somatotyping ponderal index is simply height over the cube root of weight, using the persons maximal weight, and that gives an index of a persons massiveness, you might say. But then, in order to be able to distinguish somebodys massiveness between how much of it is due to the endomorphic component, the fatty tissues, if you will, and the mesomorphic component, the more or less lean tissues, the bone and muscle, Sheldon developed what he calls the trunk index, and basically what that does is to measure the area of the chest over the lower abdominal area by means of using a planimeter which is simply a tool that measures areas, and it is fairly easy to do. You anchor the somatotype photograph, and you make a set of marks at the anatomical waist, and at the neckline. That will give you the upper trunk. And then at the gluteal fold you make another mark, and that will give you the abdominal area, and then you set up your planimeter, zero it out, and then carefully run around those edges, as I am doing here, take your reading, and that will give us the lower segment. Then do the upper segment, the upper trunk. You take your reading for that, and then the ratio of those two numbers will give you the so-called trunk index. With those three parameters, the maximal height, the somatotyping ponderal index, and the trunk index, you can enter the tables and find the persons somtatotype on a more objective basis.
Because the tables have been set up, you can do a less exacting procedure to determine a persons somatotype. You will have to take a persons height very accurately, and of course, you should try to get an accurate weight history, also, and then doing the computation for the somatotyping ponderal index is fairly simple. Everyone has a pocket computer, and it is just height over the cube root of weight. So if you have that information a persons maximal height and information on their maximal weight you can determine the somatotyping ponderal index, and then you can go to the tables, and a fairly easy way to do that would be to sort of make a guesstimation, perhaps, of one of the components maybe you would want to pick mesomorphy, the muscular and structural component. If it is a man you might think that the average is in the area of 4 to 4 ½. If they look very muscular you might go a little higher to 5. If they dont look quite as muscular you might go a little lower. So you might try out certain mesomorphic possibilities say 4 ½. If you go to that lever, then you can see in the table at a certain age that they should weigh a certain amount, and should also be a certain height, and if they are not that height, then you can go one step up or one step down. So it is possible to fit all the components together the three components I mentioned without actually doing the photograph, and taking all the measurements precisely. It wont be quite as precise, but it should be good enough, and it will give some very good information, I think, to a person.
Jim: Sheldon died on September 16, 1977 and is buried here in Pawtuxet not far from where he was born, and buried with him, largely because of his own doing, was interest in the work that he had devoted his life to. That work now lies fallow, waiting for someone to recognize it for what it was one of the first and most important fruits of American psychology.
