On October 31, 1955, doctors at Elgin State Hospital in Illinois conducted another series of X-rays on a woman who had already spent nearly 25 years inside the institution. In the surviving research records, her name does not appear. She is identified only as Patient 03109. By this point, doctors had been monitoring changes in her skeleton for several years.
Earlier scans had already shown small areas of damage in some of her bones, but this time the findings were markedly worse. There were more lesions than before, and many that doctors were already tracking had grown more severe. For most patients, that would have been alarming. But in her case, doctors already knew something highly unusual was inside those bones.
Twenty-four years earlier, when she was 27, doctors at the same psychiatric hospital had injected radium chloride directly into her bloodstream. It was not a single injection either. Her medical record describes repeated intravenous treatments between March and July of 1931. What makes this so strange is what they were trying to treat.
She did not have cancer, and the radium was not being used against a tumor. Doctors were giving it to her because they believed it might help with her mental illness. Today, that is almost impossible to understand. Radium-226 is radioactive and has a half-life of about 1,600 years.
Once inside the body, some of it can behave similarly to calcium, which means it can be incorporated into bone. We now know that sufficient exposure can cause serious damage, especially in and around the skeleton. But Patient 03109 was not the only psychiatric patient at Elgin to receive it. State records describe research conducted at the hospital during the early 1930s in which patients were given radium as an experimental treatment for mental disorders.
Even the exact number of people involved is hard to pin down. When researchers reviewed hospital records years later, they found patients who did not appear to be in the original published study. The radium treatment did not simply disappear into an old medical journal after doctors stopped believing it could help psychiatric patients. Almost 20 years later, scientists returned to look for the same people because they wanted to know how much radium was still inside their bodies.
By 1950, 14 surviving Elgin patients who had received radium were still living at the hospital. What began as an attempt to treat mental health had made them useful for a completely different kind of research. Scientists suddenly had a group of people who had been carrying radioactive material inside their bodies for nearly two decades. Elgin was also used for another unusual experiment involving long-term vitamin deficiency while the hospital itself continued to expand.
It opened in the 19th century with only 183 patients, but by the mid-1950s, more than 7,600 people were living there on an ordinary day. The strange part is that Elgin was not created to be a deliberately cruel institution. It actually began with ideas that were considered progressive at the time. The people who designed hospitals like this believed psychiatric patients needed fresh air, sunlight, open grounds, and enough personal attention for doctors to understand the individual they were treating.
So the interesting part of Elgin’s history is not simply that bad things happened there. It is how a hospital built around relatively humane ideas became large enough to hold thousands of people at once, while some of those patients were used in medical experiments involving treatments doctors were still trying to understand. To understand how Elgin ended up in that situation, it is necessary to go back to the 19th century, when building a large psychiatric hospital could honestly be presented as reform. Before specialized mental institutions became common, a person suffering from serious mental illness did not necessarily have a place designed for their treatment.
Families could try to care for someone at home, but when that became impossible, the alternatives might include poorhouses, jails, or other places never intended to provide psychiatric care. One of the most influential figures behind the reform movement was a doctor named Thomas Story Kirkbride. He believed that the environment surrounding a patient could be part of the treatment itself. That is why many hospitals built during this period were based on vast tracts of land and had those long, distinctive wings.
Patients were supposed to get fresh air, sunlight, and pleasant views. They were to have space to walk, work, read, and follow a daily routine while doctors were supposed to have enough time to observe them properly. But Kirkbride also believed these hospitals needed to remain relatively small. Around 200 patients was considered preferable, and roughly 250 was about the maximum he thought a single hospital building should hold, because the entire system depended on individual attention.
That becomes important when you realize Elgin eventually held more than 30 times that number of patients. Illinois established the Northern Illinois Hospital and Asylum for the Insane in Elgin. On April 16, 1869, the city of Elgin donated 155 acres of the Chisholm farm along with access to a nearby spring, and the state acquired hundreds of additional acres around it. Farming soon became part of the hospital.
The farm helped feed patients and reduce costs, while doctors also believed that regular work gave some patients a useful structure to their day. The main hospital was designed by Stephen Vaughan Shipman, and his plan followed the general approach associated with Kirkbride. There was a central section with long wings extending outward, allowing patients to be divided into different wards while providing more ventilation and natural light to the building. When you look at pictures of these hospitals now, you might feel immediate dread because we already know what many of them eventually became.
But families in the 1870s did not necessarily see Elgin that way. Compared to placing someone in a jail or poorhouse, a specialized hospital surrounded by open countryside could look like a major improvement. The first patients arrived on April 3, 1872. There were 183 of them.
At that point, Elgin was still close to the size its designers had imagined, so staff had a realistic chance of getting to know patients individually. The first superintendent, Dr. Edwin Kilbourne, pushed for the completion of the rest of the building, and by 1874 the main sections were finished. But the state almost immediately faced a problem that became common in the history of public psychiatric hospitals.
It paid for construction costs but did not provide enough money to care for everyone the new facility could hold. As a result, parts of the hospital remained empty until 1875. That sounds like a basic budget issue, but it points to something that kept happening. Building more beds was relatively easy.
Making sure there were enough doctors, nurses, attendants, and resources for everyone using those beds was far more difficult. As Elgin grew, some people stopped being short-term patients and became long-term residents. David Hiram Smith was one of the best-documented examples. David was the youngest son of Joseph Smith and Emma Hale Smith, born several months after his father’s death.
As an adult, he became a religious leader and missionary, but he was also a poet, painter, and singer. His mental health declined, and in 1877 he was admitted to Elgin. He remained there until his death in 1904, meaning he spent about 27 years inside the institution. Cases like David’s explain these places better than population statistics, because 27 years is not just a long course of treatment.
It is a huge portion of a human life. Doctors could retire, administrators could change, new buildings could appear, and entirely new treatments could be introduced while he was still there. David died at Elgin when he was 59 years old. With more people staying for years, the hospital had to do more than just treat psychiatric symptoms.
It needed to feed people, provide clothing, run kitchens, maintain hundreds of acres, and care for patients as they aged. By the beginning of the 20th century, Elgin was starting to operate like a small town, except that most people living there simply could not decide to leave. The numbers kept rising. In 1910, the hospital had about 1,450 patients.
By 1930, there were more than 3,450 patients. The campus expanded with them, and in 1928 Elgin added major hydrotherapy facilities. This type of treatment was used in many psychiatric hospitals and could involve baths, showers, different water temperatures, or keeping someone in water for extended periods. Doctors hoped it would calm severe agitation at a time when modern psychiatric medications did not exist.
That is important because it would not be fair to look at every old treatment and assume doctors knew it was useless. In many cases, they were working with very limited options. But that uncertainty also created room for experimentation. And it was during this period that one substance gained an almost unbelievable reputation in medicine: radium.
Marie and Pierre Curie discovered radium near the end of the 19th century, and over the following decades it became associated with both real medical advances and an enormous amount of exaggerated enthusiasm. Radiation had genuine medical uses; doctors discovered it could destroy tissue, making it useful for certain types of cancer. But because radium was new and seemed so powerful, people also began to assume it could help with all kinds of unrelated problems. It appeared in supposed health products and treatments.
Doctors even tried using it against mental illness. You might assume that doctors in 1931 simply had no idea radium could be dangerous, but that is not quite accurate. By the 1920s, the women known as the “Radium Girls” were already suffering devastating illnesses after exposure to radium while painting luminous watch dials. Several women eventually took legal action against their employer.
So medicine did not yet understand every detail of radiation exposure, but there was already evidence that radium could seriously damage the human body. That is the environment in which Elgin’s treatments began. Part of the reason appears to trace back to an earlier case recounted by Robert Rowland, a biophysicist who later spent years studying people exposed to radium. In a later oral history, Rowland described a doctor named Finley John who had tried radium during the 1920s.
According to Rowland’s recollection, John believed that one patient with symptoms related to schizophrenia had improved significantly after receiving repeated radium injections. An apparent improvement does not, of course, prove the treatment worked. But when doctors lacked reliable psychiatric treatments, something like that was enough to encourage further research. The scientist most associated with the Elgin work was Herman Schlundt, a chemistry professor from Missouri.
Schlundt was particularly interested in radium itself, including how much was given, how much remained inside the body, and how quickly it was eliminated. According to Rowland’s later account, patients generally received repeated doses of radium-226, often about a week apart, and some continued receiving injections for months. A research paper on the Elgin patients was published in 1933, but there was no convincing evidence that radium was useful for the mental illnesses it was supposed to treat. The exact number of patients who received the treatment also remains surprisingly unclear.
State records indicate the treatments occurred roughly between 1931 and 1933. When researchers later went through Elgin’s files, Rowland recalled identifying about 41 possible people who received treatment, although he also said the exact number remained uncertain. So there is no single perfect document showing every patient and every injection given. What is known is that psychiatric patients at Elgin received radium.
Individual medical records remained, and scientists returned to study some of those same people decades later. The question of consent is more difficult. The remaining public records do not allow us to reconstruct exactly what each patient was told or what kind of permission was obtained. It would not be accurate to invent a scene in which patients were secretly forced to receive injections, but describing them as ordinary research volunteers would not make sense either.
They were psychiatric patients already living inside a state institution, and that institution controlled their medical care, their routine, and in many cases, their ability to leave. Patient 03109 provides one of the clearest remaining examples of what happened to a specific individual. She was born on January 27, 1904, and on November 15, 1930, at age 26, she was admitted to Elgin. Her diagnosis was recorded using the outdated term “dementia praecox of the hebephrenic type,” historical psychiatric language associated with what would later be understood differently as schizophrenia.
Just a few months after her admission, the radium treatment began. Her record states that radium chloride was given intravenously between March and July of 1931. She was 27 years old. There are many things we do not know about what happened in that treatment room.
We do not know exactly how doctors explained the procedure, what she thought the injections would do, or how much she understood about the substance being put into her body. What we know is that she was living inside a psychiatric hospital and depended on the medical professionals around her for treatment. Her life after the injections did not suddenly turn into a recovery story. In 1932, she developed a serious lung infection complicated by empyema, meaning a collection of infected fluid around her lung.
She needed a surgical procedure to drain that fluid. Later records indicate she worked in an office for several years. That is a small detail, but it gives us something beyond just a diagnosis or an X-ray image. At least for part of her time at Elgin, she had a routine and some kind of work.
Her mental condition later deteriorated, and by 1941 her record described her as inactive. Then, about 20 years after the radium injections, scientists began examining her bones more closely. A scan in 1951 showed changes doctors considered consistent with radium deposits. They found small areas where bone had been lost in her right forearm, and changes in the internal structure of the bones in her lower legs.
She was scanned again in 1953. Then came October 31, 1955, where this story began. This time, doctors reported that some skeletal lesions had increased significantly in number and severity. Two years later, she developed bladder cancer.
The disease spread to her lungs, and she died on September 29, 1957, at age 53. An autopsy was performed, and her remains were cremated. It would be easy to say the radium caused her cancer and led to her death, but the surviving evidence does not confirm that link. The documented facts are already enough.
She received repeated intravenous radium treatments when she was 27. Two decades later, scientists could still study the radioactive material that remained inside her body. Doctors documented changes to her skeleton related to radium deposits. And after her death, samples of her bones and other tissues remained useful for research.
So even though the psychiatric treatment itself ended in 1931, her connection to the radium story continued for the rest of her life. When scientists returned to her in the 1950s, they were no longer really interested in treating mental illness. By that time, the world had completely changed. When the Elgin patients first received radium, there was no atomic bomb, no U.
S. Atomic Energy Commission, and no Argonne National Laboratory. The Elgin treatments came before the atomic age. What happened after World War II was different.
Scientists suddenly needed to understand what happens when radioactive materials remain inside the human body for years, especially because of growing concerns about plutonium in the nuclear industry. Radium was useful for comparison because both radium and plutonium produce alpha radiation and can be deposited in bone. And the Elgin patients already had something researchers could not quickly create. They had time.
By 1950, some had been carrying radium inside their bodies for nearly 20 years. If a new study began that year, you could not wait until 1970 to learn the results of 20 years of internal exposure. At Elgin, a group of people had already experienced that decades earlier. So researchers went back.
In the summer of 1950, a formal clinical study began involving 24 people who had previously received radium. Fourteen of them were Elgin patients who had received intravenous radium chloride and were still living at the hospital. Nearly 20 years had passed. The country had lived through the Great Depression and World War II.
Nuclear weapons had been invented, and the scientific world outside Elgin had changed enormously. But 14 of the people researchers wanted to find were still living in the same institution. Scientists went through old hospital files, trying to match names and patient records with the letters and codes used in earlier scientific papers. Once they identified the surviving patients, they conducted physical exams, blood tests, and skeletal X-rays while attempting to estimate how much radium remained inside each person’s body.
Of the fourteen psychiatric patients at Elgin, only one was considered able to provide researchers with a detailed and satisfactory medical history. So for all the others, investigators relied heavily on what the hospital had recorded. The institution remembered the injections even when the patient could not explain them. Researchers estimated that a relatively small percentage of the original radium remained after about two decades.
But radium-226 decays very slowly. It can also behave somewhat like calcium, so the body may deposit it in bone, where nearby tissue can continue receiving radiation from inside the skeleton. That is why researchers were so interested in X-rays and bone samples. Patient 03109 became part of that work as well.
After her death, her research file listed samples of femur, rib, vertebrae, and one of her teeth. In 1931, doctors introduced radium into her body because they hoped it would improve her mental condition. By the 1950s, that theory had almost disappeared from the story. Now researchers were interested because the radium was still there.
Elgin’s usefulness for research did not only involve radiation. During the 1940s, another group of psychiatric patients became part of a long-term study on vitamin deficiency. A report published in 1946 described research involving 36 male patients. Scientists wanted to understand what happens when people receive diets restricted in thiamine and riboflavin, both B vitamins.
The experiment was designed to last three years. Patients were divided into groups so researchers could compare those receiving restricted diets with others receiving supplements or the hospital’s regular diet. Their food was prepared in a controlled kitchen, making it possible to track what they ate over long periods. One reason institutional patients were useful was simply that researchers needed people likely to remain available.
A person living an ordinary life might move away or stop participating. At Elgin, patients were already living under the hospital’s supervision. The researchers said they took precautions to prevent serious harm and that the study was intended to answer legitimate questions about nutrition. But they were still deliberately restricting essential nutrients for psychiatric patients over long periods.
With relatively mild deficiency, researchers noted behavioral changes such as patients becoming less active and less interested in their surroundings. When severe thiamine deficiency was induced, physical and neurological effects became more pronounced, and afterward researchers studied what happened when patients were given thiamine again. Scientifically, that gave them useful information. But again, the research benefited from the fact that institutional patients were unusually easy to observe for years.
All of this was happening while Elgin itself was becoming larger than ever. In 1949, the hospital population reached 6,025. By 1955, the same year doctors found worsening skeletal changes in Patient 03109, Elgin reached its historical peak with an average daily population of 7,644 people. Compare that to the original idea that preferred only about 200 patients.
Of course, those thousands were not all in one building, because Elgin had expanded into a large campus. But more buildings did not automatically mean more personal attention. Every new ward needed doctors, nurses, attendants, food, and supervision. The larger the system became, the more energy it had to spend just keeping itself running.
This happened in state hospitals across the country. More people were admitted, more wards were built, and then those new beds could be filled too. Eventually, an institution could become very efficient at housing a huge population while becoming less able to provide the personal treatment it was originally created for. What makes Elgin interesting is that advanced research and overcrowding existed at the same time.
The hospital could host scientists doing sophisticated work while ordinary wards suffered enormous pressure. Medical progress in one part of the institution did not mean everyone living there was getting better care. During the 1950s, psychiatry began to change rapidly. New medications made it possible for some people to live outside hospitals where they would once have stayed for years, and legal and social attitudes toward large institutions were also shifting.
Elgin’s population gradually declined. By 1965, the average daily population had fallen to just over 5,100, and by 1970 it was about 3,300. This was part of the larger process known as deinstitutionalization. For many patients, medication and community treatment offered a better alternative to spending years in a state hospital, although that only worked properly when there was enough support outside the institution.
Elgin did not disappear completely. In 1975, the hospital was renamed the Elgin Mental Health Center, while the original central building remained standing until it was eventually demolished in 1993. One of the clearest physical reminders of the old institution is elsewhere. Hilltop Cemetery was established in 1933, around the same time Elgin’s known radium treatments were winding down.
The first burial took place on October 27 of that year. Today, there are 974 marked grave sites, almost all belonging to former Elgin patients. Hospitals like this needed cemeteries because some people spent enormous portions of their lives inside the institution. Some remained close to their families and were moved home when they died.
Others had become separated from relatives for years, or no longer had anyone able to make those arrangements. For those people, the hospital was where they slept, ate, worked, received treatment, and were eventually buried. For some patients, admission was not a temporary medical event. It became the place where they spent the rest of their lives.
That brings us back to Patient 03109. She arrived at Elgin in November 1930 when she was 26. A few months later, doctors began giving her radium chloride. The injections continued between March and July 1931.
Whatever doctors hoped radium would do for mental illness, it never became an accepted psychiatric treatment. That theory faded. But some of the radium did not fade. Nearly 20 years later, researchers returned because the substance that failed as a psychiatric treatment had become scientifically useful for another reason.
They took new X-rays, studied changes in her skeleton, and compared what they saw with previous records. After her death, they studied samples taken from her bones and teeth. That research produced useful scientific knowledge about what happens when radium remains inside the human body for many years. But the opportunity to collect that information existed because psychiatric patients had been given radium decades earlier.
That is what makes Elgin more complicated than a simple story about one terrible doctor. You do not need a single person deliberately harming patients for the system to cause harm. A doctor could sincerely believe an experimental treatment might work. A scientist could sincerely want information that might protect other people.
A state could sincerely believe it was building a more humane psychiatric system. All of those things could be true while the people inside that system still bore the consequences. The important difference is power. A person living independently might be able to refuse treatment, leave a doctor’s office, or seek a second opinion.
A psychiatric patient living inside an institution might depend on that very system for food, shelter, medicine, treatment, and any possibility of eventually leaving. That does not prove every patient at Elgin was forced to participate in every experiment. But it makes questions about consent far more important. How much real freedom does a person have to refuse when the people providing treatment control almost every other aspect of their life?
Elgin still exists today as a mental health center, and it is important not to confuse the old state hospital’s history with the people receiving care there now. Psychiatric treatment has changed enormously. Research standards have changed, and the huge patient populations that marked the old asylum era are gone. The troubling part of this history was never that mentally ill people lived at Elgin.
What matters is what can happen when vulnerable people live inside a powerful institution during a period when doctors were experimenting with treatments they did not fully understand. More than 90 years after the radium injections began, state records still contain documents about the people who received them. And inside those records is the woman we started with, Patient 03109. She was born in 1904, entered Elgin in 1930, and received radium in 1931.
Years later, researchers examined her skeleton again and again because they wanted to understand what the substance had done after remaining inside her body for so long. She died in 1957. Her research records preserve her diagnosis, her treatment dates, her medical problems, the skeletal findings, the tissue samples, and the cause of death. What they do not provide, at least in the public version of that record, is her name.
There is a understandable reason for that in research archives. But after reading Elgin’s history, it is striking how fitting that is. Large institutions can collect enormous amounts of information about a person. They can record when someone arrived, what diagnosis they received, what treatment they got, and what happened to their body afterward.
The system could remember almost everything it needed while making it surprisingly easy for the real person to disappear behind a patient number. When Elgin opened in 1872, its philosophy was based on keeping the institution small enough for people to receive individual attention. By the 1950s, more than 7,600 patients were living there on an ordinary day. Some had already spent decades inside, and others became useful to researchers, partly because the institution made it possible to follow them for such long periods.
Not far from the modern facility, Hilltop Cemetery still holds 974 marked graves, almost entirely belonging to former Elgin patients. Each one of those graves represents a person who had a life before entering the hospital, even if very little of that life remains in the records now. Elgin kept a vast amount of medical information about some of these people, especially when their bodies became useful to science. But keeping information about someone is not the same as remembering who they were.
The old central building disappeared in 1993, but the case files, the X-rays, and the rows of graves remain, meaning the people who lived at Elgin left behind a long record long after the treatments that brought radium into their bodies were abandoned.
