ST. LOUIS (NewsNation) — The summertime of 1953 successful St. Louis was relentless. The vigor bushed down connected the ceramic facade of Pruitt-Igoe, the aerial heavy, clinging to 33 factual towers that astir seemed to clasp the prima captive. Children played outside, the shouts of their games echoing betwixt high-rises.
And past the fog would come.
'My authorities utilized maine similar a Guinea pig'
It hissed from nozzles connected vehicles that rolled dilatory down the streets. It drifted from rooftops, wherever “maintenance men” had stood installing them conscionable days earlier, wearing protective gear. A unreality that hung heavy successful the aerial — clinging to skin, seeping into lungs, leaving down a chemic tang.
James Caldwell, who grew up successful Pruitt-Igoe, remembers chasing aft it arsenic a child.
“It was summertime, it was hot, we’d tally done it arsenic accelerated arsenic we could and effort to conscionable chill ourselves off. It stuck to you,” said Caldwell. “It was a regular flatbed truck, but it had a large instrumentality connected the back, and it had a large nozzle that sprayed a fog. You couldn’t adjacent spot done it; it was that thick, and it would adhere to our skin. And arsenic acold arsenic the guys connected apical of the buildings, they tried to represent them to america arsenic attraction workers, but what are the attraction workers doing successful a hazmat suit? They had masks and goggles.”
For Jacquelyn Russell, the representation of the fog that moved similar a shade is visceral.
“It was specified a sickening, nauseating … it was horrible. It would thrust existent slow. …You couldn’t spot done it, that’s however heavy it was. It’s a sickening smell, it’s thing chemical.”
She remembers headaches, nausea, dizziness. Others retrieve worse.
“That’s what I remember, it made maine sick,” said Cecil Hughes. “My momma had to instrumentality maine to the exigency room.”
An American metropolis chosen: Moscow 2.0
What the children of Pruitt-Igoe ne'er knew was that they were surviving wrong a authorities experiment.
In the 1950s and '60s, the U.S. Army sprayed zinc cadmium sulfide — a compound containing cadmium, a known carcinogen — successful the metropolis of St. Louis. The authorities present admits to a secretive bid of Cold War-era tests, including 1 dubbed “Large Area Coverage.” More than 30 tests were carried retired successful the U.S. and Canada spraying zinc cadmium sulfide from planes, rooftops and vehicles.
St. Louis was chosen for spraying experiments specifically due to the fact that of its carnal similarities to Moscow. According to the National Research Council, its colonisation density, terrain and stream entree made it an perfect analog for the Soviet city. The residents — astir of them Black, astir of them mediocre — accidental they were ne'er told.
“It was a lose-lose concern for america successful Pruitt-Igoe. We were subjects, we were subjects,” said Ben Phillips.
“They didn’t inquire our permission. We didn’t inquire for them to spray us. My authorities utilized maine similar I was a Guinea pig,” Hughes said.
“If you’re going to test, you person to pass the radical you’re investigating on; it’s disrespectful, it’s truly inhumane,” said Chester A. Deanes Jr.
The spraying lasted for years. But the radical who lived nether the fog accidental they inactive transportation its weight, and with that burden, a troubling uncertainty. The residents present wonder: How overmuch of their sickness, their cancers, mightiness hint backmost to those years nether the fog?
“I mislaid my 2 older siblings to cancer. I mislaid a member past month,” Russell said. “Now each of a sudden, [residents] person kidney cancer? Brain cancer? Eye cancer? Any benignant of crab you tin enactment anywhere, radical person been dying from that from Pruitt-Igoe.”
“My parents’ friends started dying,” Phillips recounted, speaking of erstwhile helium archetypal became acrophobic astir the wellness issues successful his community. “I went to 10 funerals, and astir 7 oregon 8 of them were cancer-related deaths.”
Philips himself had to person a tumor removed from his near eardrum that took his proceeding — helium says helium inactive remembers erstwhile his small sister started having convulsions earlier she was 2 years old, past those convulsions stopped aft his household relocated distant from Pruitt-Igoe.
Dr. Michael Starks had crab of the near kidney and had to person it partially removed.
Caldwell’s dependable catches erstwhile helium describes his ain diagnosis.
“I’ve been diagnosed precocious with a uncommon signifier of lymphoma. I person a mutated chromosome, and eventually, that mutation is going to crook my humor cells into cancerous cells," helium said.
Caldwell says it doesn’t tally successful his family. He worries for his children.
The government’s response
The Army contends determination was nary wellness hazard from the spraying tests. In a connection to NewsNation, it pointed to reports similar a 1994 reappraisal done by the Army’s ain Center for Health Promotion and Preventive Medicine and a 1997 study by the National Research Council — some concluding determination was “no evidence” the spraying posed a wellness risk.
But a person look reveals that erstwhile it comes to the NRC review, that whitethorn not beryllium the full story. In fact, the NRC study acknowledges that repeated vulnerability to zinc cadmium sulfide could origin kidney and bony toxicity oregon lung crab if levels were precocious enough.
Additionally, the NRC admitted it could not afloat measure the hazard — due to the fact that immoderate of the cardinal Army records were inactive classified, the Army said, for nationalist information reasons. Perhaps much troubling, the NRC wrote that different cardinal Army records were “missing” — the Army couldn’t find them.
The NRC considered conducting its ain survey but concluded it wasn’t feasible. In short, it did not trial the site, cod samples oregon trial residents for its review. And the NRC did not person entree to each the data. Their study was based connected what the Army gave them and not what the Army either could not find oregon withheld.
Residents wonderment if they volition ever spot the afloat scope of the experiments they were unwitting participants in. They judge the secrecy and delays are nary accident.
“They’re waiting america out,” Caldwell said.
“They’re waiting connected each of america to die,” Phillips added. “And erstwhile we die, possibly they’re going to hold for our kids to die.”
A researcher’s quest
The enigma mightiness person stayed buried if not for Dr. Lisa Martino-Taylor.
The sociologist, researcher and present retired module subordinate from Southern Illinois University Edwardsville spent decades of her vocation trying to portion unneurotic what happened, combing done thousands of declassified files, pushing for the merchandise of the ones that stay secret.
It each started, she says, erstwhile 2 radical approached her separately: a workfellow with bosom crab and a neighbour who had developed a encephalon tumor. Both told her they remembered spraying from their childhoods.
“[My neighbour said], ‘I was treated for a encephalon tumor astir a decennary ago, and I deliberation it was related to thing that happened to maine erstwhile I was little,’ And I said, ‘Well, what was that?’ And she said, ‘I was sprayed connected the playground astatine a schoolhouse successful St. Louis.’ And I thought, however tin this be? These 2 radical don’t cognize each other, and they were coming to maine days isolated with the aforesaid unusual story,” said Martino-Taylor. “At archetypal I didn’t judge it. I thought, 'This is conscionable truly hard for maine to believe.'”
Martino-Taylor promised she’d look into it anyway. And erstwhile she began digging, the insubstantial way stunned her.
“What the subject had told people, astatine slightest officials successful St. Louis, was that they were going to conceal these cities nether a unreality successful lawsuit of Soviet attack. That was conscionable benignant of a veneer, a screen communicative if you will. They were not astatine each telling the information astir what they were really doing and wherefore they were doing it,” said Martino-Taylor. She believes it was “part of a overmuch larger coordinated survey that the Army Chemical Corps was liable for, that progressive the accumulation and investigating of radiological weapons.”
Martino Taylor says her probe reveals the precise men who designed the St. Louis tests were experts successful radiological warfare. Brigadier General William Creasy led the Army Chemical Corps, the subdivision starring America’s concealed radiological weapons programme during the Cold War. He brought connected Philip Leighton, his apical chemist, who was the Army’s starring authorization connected utilizing radioactive particles successful aerosol signifier — foglike clouds designed to drift implicit force terrain.
“Yes. He was the expert,” Martino-Taylor said.
Secrets hidden successful plain sight
Martino-Taylor’s enactment revealed chilling details from this era, erstwhile the U.S. authorities conducted quality experiments connected its ain radical successful the sanction of preparing for the Soviet threat.
American children successful state-run institutions similar the Fernald School were fed radioactive oatmeal arsenic portion of studies by MIT sponsored by the Atomic Energy Commission.
The children, immoderate of them orphans, were told they’d joined a “science club” and were promised a quart of beverage a day, a travel to a shot game, a travel to the beach. A transcript of the 1994 legislature proceeding shows those children, present grown, describing being told the oatmeal was “just vitamins” — and recalling the wellness problems that followed: “lumps connected my arms,” “my stomach.”
Pregnant women were besides unknowingly fixed radioactive robust astatine apical hospitals successful Tennessee and California — to survey however radiation crossed the placenta. Some aboriginal reported miscarriage, unwellness oregon commencement defects. A people enactment suit resulted successful a colony successful the 1990s.
“We cognize that they were giving radioactive cocktails to large women. We cognize that they were feeding radioactive oatmeal to children successful authorities schools. They’ve admitted to those things, and they won’t merchandise the worldly related to St. Louis,” said Martino-Taylor.
The programme that 'wasn’t intended to beryllium found'
Martino-Taylor worked to declassify antecedently hidden documents, including Army records, and synthesized records already nationalist and articles regarding this epoch of U.S. authorities testing.
“That was 1 of the things that truly stood retired to maine successful each of the radiological weapons experiments, that determination were layers of secrecy. It was an offshoot of the atomic weaponry project, and a batch of the radical who were moving successful the aboriginal enactment of the radiological weapons experimentation were progressive successful the atomic weaponry project. It was a four-pronged program: They wanted to bash ingestion, inhalation, injection and afloat assemblage scan connected humans," she said.
As she went deeper, she says she astir needed to follow the lexicon of a codebreaker — the connection was purposely veiled and obfuscated.
“They were speaking successful coded languages. Radiological weapons was really called ‘RW.’ They called plutonium ‘product,’ and truthful they would notation to ‘the product.’ So erstwhile you cognize however they notation to these antithetic tests, oregon the radioactive components of these tests, you spot precisely what they're doing. It's conscionable hidden successful plain sight,” said Martino-Taylor.
But still, she says, erstwhile it comes to St. Louis, determination is simply a shroud of secrecy and documents she inactive has not been capable to get the authorities to declassify.
“It truly took going done thousands of documents, pulling those together, and benignant of mapping those out, and pursuing each pb arsenic acold arsenic that could spell to beryllium capable to recognize that this was a programme that was an violative program, not a antiaircraft program. An violative programme that was unsocial and adjacent much secretive than the atomic weaponry project. They didn't privation anyone to observe this program, which is wherefore determination were each these layers of secrecy to it. It wasn't intended to beryllium found.”
She says she inactive has not recovered a singular “smoking gun” papers definitively showing radioactive worldly was sprayed successful St. Louis, but she besides doubts whether a azygous specified papers exists, fixed the clandestine and layered quality of the program. She believes the information lies determination successful the discourse of who ran the study, erstwhile they decided to behaviour it and what they did with the results.
What was sprayed successful St. Louis?
When asked if she believes the U.S. authorities sprayed immoderate benignant of radioactive worldly connected the residents of St. Louis, Martino-Taylor answers plainly: “I judge that they did. There’s truthful overmuch contextual grounds that points that way.”
She examined who was progressive successful the improvement of the St. Louis tests and recovered Creasey and Leighton.
For Leighton’s part, successful summation to his relation successful the St. Louis spraying tests, helium was besides the manager of operations astatine Dugway Proving Ground — a distant and secretive installation successful Utah utilized by the Army to trial chemic and radioactive materials. It was the Army Chemical Corps’ main tract for experiments with chemic and radiological weapons, including open-air releases to survey however they spread.
Martino-Taylor was disturbed to find retired not lone astir Leighton’s dual relation but grounds that the information from St. Louis was gathered and past straight compared with Dugway Proving Ground.
Martino-Taylor besides says the timing is notable.
“[In 1952], they were looking for a metropolis to trial their violative weapons program. They wanted to bash it. They expressed this successful documents. St. Louis was their chosen city; that was their analog metropolis to Moscow. They wanted to bash this successful 1953, and they showed up successful 1953 successful St. Louis.”
Additionally, Martino-Taylor says immoderate of the St. Louis records she uncovered included notes astir decontamination of the rental motortruck they utilized for the spraying — instructions she believes are inconsistent with zinc cadmium sulfide alone.
She believes these things were not coincidences.
“There is truthful overmuch contextual grounds to this. They person documents that accidental we mean to bash an open-air experimentation utilizing radioactive material. They wanted to spray an municipality area. They wanted to make radiological weapons to usage against the Soviet Union. St. Louis was their chosen city,” said Martino-Taylor.
“From the 1940s, they were actively processing radiological weapons, galore of these progressive open-air spraying. They compared the St. Louis information to the information astatine Dugway Proving Ground, which was a radiological weapons proving ground. When you look astatine each of these elements and these pieces of evidence. It each points that way.”
There is 1 papers that Martino-Taylor has ne'er been capable to unearth. It's inactive classified. A bid of Joint Quarterly Reports item the spraying tests, each written by Leighton himself. The past 1 is missing — it’s called Joint Quarterly Report 5 — and NewsNation tried to get it.
Our squad filed a Freedom of Information Act petition connected May 5, 2025. By law, the authorities indispensable respond to a FOIA wrong 20 moving days. As of publication, it has been much than 3 months contempt aggregate travel ups. The soundlessness connected the portion of the authorities is called a constructive denial.
What did the Army know?
The substance the Army does admit to spraying is simply a chemic called zinc cadmium sulfide, which contains cadmium, present known to beryllium a quality carcinogen. But did the designers of this survey cognize astatine that clip that the chemic they were utilizing to fog much than 10,000 Americans could beryllium harmful to their health? Martino-Taylor says she believes they did.
“[Philip Leighton] was precise good alert that cadmium was problematic. Using cadmium sulfide was toxic, and helium was unfastened astir that. Even astatine that time, they knew that this was toxic,” said Martino-Taylor.
We looked into this further. Historian Leonard Cole contends Leighton, the Army’s apical chemist moving connected this spraying experiment, wrote 2 pages astir zinc cadmium sulfide successful his ain 1955 manual, titled “The Stanford Fluorescent-Particle Tracer Technique: An Operational Manual (U.S. Chemical Corps Research and Development Program).”
According to Cole, Leighton wrote, “Compounds of zinc and cadmium are some known to beryllium poisonous erstwhile taken into the quality strategy … the possibilities of toxic effects indispensable beryllium considered.” The manual served arsenic a protocol for aerosol tracer tests.
Erin Brockovich weighs in
Renowned activistic Erin Brockovich says the communicative successful St. Louis reminds her of cases wherever the information was hidden.
“I deliberation my remark was, 'Are we W-T-F kidding me?' I mean, what the hell? … It’s awful. The biggest thing, and I’ve learned successful 30 years, is it’s ever the cover-up that enrages people, that hurts people. Communities tin grip the truth. What they don’t grip — and wherever they’ll extremity a standard — is the lie. So this has been a cover-up, and I deliberation modern-day agencies beryllium it to them, the truth,” said Brockovich.
When asked if she thinks there’s been a cover-up, she replied, “It definite looks that way."
What’s next
Meanwhile, the residents’ combat has present reached Congress. We spoke with Representative Wesley Bell of Missouri.
“When American citizens person been impacted and exposed to chemicals due to the fact that — specifically due to the fact that of the national authorities — I deliberation that we should, arsenic Democrats and Republicans, we should each bash the close happening and marque definite to marque these folks full again,” said Rep. Bell. “Get them the compensation they merit and the attraction that they request and besides deserve.”
Rep. Bell is advocating for legislation, the Radiation Exposure Compensation Act. If passed, it would supply payouts to Americans who tin beryllium they are exposed to radiation during the Cold War. But Pruitt-Igoe residents stay locked retired of compensation programs similar RECA. They are not capable to beryllium immoderate vulnerability to radiation, and they accidental cardinal records that could assistance illuminate what was contained successful the spray stay classified oregon missing.
And truthful they support fighting.
“We privation the truth. Whatever the information is, we privation to cognize the truth. I don’t deliberation we’re getting it now,” Phillips said. “We gotta combat this. If we don’t win, they’re going to cognize they’ve been successful a fight.”
Many of the residents accidental they near the factual high-rises of Pruitt-Igoe to serve. Both Deanes Jr. and Dr. Starks are U.S. Air Force veterans. They accidental the betrayal from their ain state carries a peculiarly crisp sting.
“We person died for America, we person fought for America,” said Deanes. “This full happening is built upon hypocrisy, that’s wherefore we’re going done this, hypocrisy. You dainty maine similar you dainty your parent oregon your father, oregon your sister oregon brother. That’s each we’re looking for.”
Hughes says helium has a informing for each Americans.
“It tin hap to you, don’t get duped and deliberation it can’t hap to you. We didn’t deliberation it was going to hap to us. We were babies, kids. It tin hap to you.”
