Asbestos: A Conspiracy 4,500 Years in the Making
They knew. They always knew.
Nearly 2,000 years ago, Roman historian Pliny the Elder documented asbestos workers dying from "sickness of the lungs"—watching slaves fashion crude respirators from animal bladders while weaving what he called "funeral dress for kings." The people closest to the dust understood the danger. The people farthest away admired the spectacle, collected the profits, and buried the evidence. That pattern never changed.
Asbestos: A Conspiracy 4,500 Years in the Making traces humanity's 4,500-year relationship with the mineral the ancient Greeks named "asbestos"—meaning indestructible. From Stone Age Finnish pottery (2500 BCE) to the $70+ billion in legal damages paid by modern corporations, we uncover how a material praised for safety became a source of sickness, litigation, and grief.
Each episode explores:
- Ancient origins: The salamander myth that persisted for 2,000 years, the Roman tablecloths that cleaned themselves in fire, the sacred flames kept burning with asbestos wicks
- The industrial cover-up: Internal documents proving companies knew asbestos caused cancer since the 1930s—and suppressed the evidence for 40 years
- Modern consequences: Why mesothelioma claims 3,000 American lives annually, and why $30+ billion sits in asbestos trust funds waiting for victims who never file
- The science of denial: How manufactured doubt delayed regulation for decades, using the same tactics as the tobacco industry—sometimes with the same scientists
Whether you're a history enthusiast, legal professional, medical researcher, or someone seeking answers after asbestos exposure, this podcast reveals the uncomfortable truth: the longest-running industrial cover-up in human history isn't ancient history. It's still happening.

Episode 22: The Saranac Coverup
In 1936, nine asbestos companies funded research at Saranac Laboratory with a contract clause making all results their "property" — publication only "if deemed desirable." When Dr. LeRoy Upson Gardner discovered an 81.8% tumor rate in asbestos-exposed mice, he couldn't publish. His own scientific integrity — recommending the cancer data be omitted until controlled experiments could confirm it — gave the industry exactly the cover it needed. Gardner applied for independent funding to escape the trap. The NCI rejected him. Six months after writing "I hope, before I die, the opportunity may be afforded us," he was dead at 57. The companies met, voted to delete all cancer references, and buried the findings for 52 years.
Key Takeaways
- November 20, 1936: Nine companies — Johns-Manville, Raybestos-Manhattan, Keasbey & Mattison, U.S. Gypsum, and five others — signed a contract owning Gardner's research before he conducted it.
- February 1943: Gardner documented 8/11 mice with lung tumors, 9/11 total with cancer (81.8%) — 16x higher than controls. He also found 11 human lung cancer cases in Quebec miners, including 2 mesotheliomas.
- Gardner himself recommended omitting cancer from the report pending controlled experiments. After his death, his own words became the industry's "permission slip" for permanent suppression.
- January 1947: Sponsor companies voted that publications "would not include any objectionable material" — defined as "any relation between asbestos and cancer."
- 1995: Dr. Gerrit Schepers finally published the suppressed findings — 52 years after Gardner's discovery (PMID: 7793430).

EPISODE TRANSCRIPT
COLD OPEN - THE CURE COTTAGE
HOST 1: Picture the Adirondack Mountains. 1917. A man arrives at Saranac Lake for the fresh air. And to die.
HOST 2: Not one for the tourism brochure.
HOST 1: Tuberculosis. In 1917, it was essentially a death sentence. But Saranac Lake had something special — a sanatorium founded by a doctor named Edward Livingston Trudeau who believed fresh mountain air and rest could cure the incurable.
HOST 2: "Cure cottages." For people who came there to die.
HOST 1: And some of them didn't die. The man who arrived in 1917 was named LeRoy Upson Gardner. He was 28 years old. An assistant professor of pathology at Yale. And he was dying of tuberculosis.
HOST 2: Let me guess — he recovered.
HOST 1: He recovered. Whatever combination of mountain air and luck and medical care — he beat it. And then he stayed.
HOST 2: Stayed to do what?
HOST 1: He started working at the Saranac Laboratory — the research facility connected to the sanatorium. By 1927, he was director. By 1936, he had a problem: the laboratory was running out of money. And that's when nine asbestos companies made him an offer.
HOST 2: Nine companies. Offering money to a struggling laboratory. I'm sure there were no strings attached.
HOST 1: The cure cottage that saved his life —
HOST 2: — became the laboratory that buried his greatest discovery. This is Episode 22: The Saranac Coverup.

THE CONTRACT - NOVEMBER 20, 1936
HOST 1: November 20, 1936. A letter arrives at Saranac Laboratory. It authorizes Dr. Gardner to begin studies on asbestos dust. The funding: nine companies — Johns-Manville, Raybestos-Manhattan, Keasbey and Mattison, U.S. Gypsum, and five others.
HOST 2: Nine competitors. Working together. That's never good for the workers.
HOST 1: Just like we saw last episode with the trade associations. But this contract had something different. Something worse.
HOST 2: Worse than coordinated silence?
HOST 1: Buried in the letter was a clause — and I'm quoting now — that the results of Gardner's research would be the "property of those advancing the required funds."
HOST 2: So they owned whatever he found. Before he found it.
HOST 1: And here's the critical part: publication would only occur "if deemed desirable" by the sponsors.
HOST 2: "If deemed desirable." They put that in writing. In 1936.
HOST 1: They put that in writing. The industry had learned from Simpson — "the less said about asbestos, the better." Now they were institutionalizing it. Buying the right to silence science before the science even happened.
HOST 2: And Gardner signed it. A Yale pathologist signed away his right to publish.
HOST 1: Money. The Great Depression had gutted charitable giving. The laboratory was struggling. Gardner had been investigating silicosis — a lung disease from silica dust — and asbestos research was a natural extension. The companies offered five thousand dollars a year.
HOST 2: Five thousand a year. Split nine ways. That's what it cost to own a man's science.
THE MOUSE EXPERIMENTS - 1936-1943
HOST 1: He didn't know what he'd find yet. The experiments were supposed to answer basic questions about asbestosis. Nobody expected what Gardner would actually discover.
HOST 2: Cancer.
HOST 1: Cancer. From 1936 to 1943, Gardner and his team ran systematic experiments. Over 800 mice exposed to different dusts — silica, quartz, flint, and asbestos. The asbestos mice inhaled long chrysotile fibers for 15 to 24 months.
HOST 2: He wasn't even looking for cancer.
HOST 1: He was looking for lung disease. The cancer was an accident. In February 1943, Gardner wrote up his findings. Under the section on cancer, he documented what he'd found in 11 mice that had survived long-fiber asbestos exposure.
HOST 2: Eleven mice. How many got tumors?
HOST 1: Eight developed malignant tumors in their lungs. Eight had tumors in other organs. In total, nine of the eleven had cancer somewhere in their bodies. And then Gardner wrote this sentence: "The incidence rate 81.8% is excessive."
HOST 2: "Excessive." That's one word for it.
HOST 1: He compared it to mice exposed to other dusts for the same length of time. Average tumor rate? About 19%. The asbestos mice had tumors at rates sixteen times higher than average.
HOST 2: Sixteen times. And he couldn't tell anyone.
THE TRAP - SCIENTIFIC INTEGRITY AS COVER
HOST 1: He couldn't publish. And worse — he knew the experiments had a flaw. The mice weren't genetically controlled. He'd accidentally used a strain unusually susceptible to cancer.
HOST 2: So even if he could publish, the industry would attack the methodology.
HOST 1: Exactly. He needed to redo the experiment with proper controls. Five hundred mice, bred for cancer resistance. Two to three years of careful work. But that required money.
HOST 2: Money he couldn't ask the sponsors for. Because they'd know what he was looking for.
HOST 1: And here's the detail that makes this story more complicated than a simple coverup. In February 1943, Gardner wrote a cover letter to Vandiver Brown — the same Johns-Manville lawyer who held the contract. And in that letter, Gardner himself recommended leaving the cancer data out of the report.
HOST 2: Gardner recommended it?
HOST 1: His exact words: "The question of cancer susceptibility now seems more significant than I had previously imagined. I believe I can obtain support for repeating it from the cancer research group. As it will take two or three years to complete such a study, I believe it would better be omitted from the present report."
HOST 2: So his own scientific integrity —
HOST 1: Gave the industry exactly the cover it needed. Gardner was being honest. He knew the data was suggestive but not conclusive. He wanted to do the experiment properly before publishing. That's good science.
HOST 2: And terrible strategy. Because once he was dead, those words — "omitted from the present report" — became the industry's permission slip.
THE NCI REJECTION
HOST 1: So in March 1943, he applied for a ten thousand dollar grant from the National Cancer Institute. Independent funding. A way out of the contract.
HOST 2: The one escape hatch.
HOST 1: January 8, 1944. A committee chaired by Dr. Ludvig Hektoen — the "grand old man of American medicine" — reviewed Gardner's application. They rejected it. Unanimously.
HOST 2: On what grounds?
HOST 1: The critique was scientifically sound — without genetic controls, the 81.8% figure "doesn't mean anything." Some mouse strains naturally develop cancer at high rates.
HOST 2: So they were technically right.
HOST 1: About the flaw? Yes. But here's the tragedy: Gardner wasn't asking the NCI to accept his flawed results. He was asking for ten thousand dollars to conduct proper experiments that would answer the question definitively. They said no.
HOST 2: And that meant Gardner stayed trapped. Owned by nine companies who didn't want answers.
"BEFORE I DIE"
HOST 1: The one door that could have freed him —
HOST 2: — closed in his face. And then?
HOST 1: April 8, 1946. Six months before his death. Gardner writes a letter to J.P. Woodard at Johns-Manville. He wants to review chest X-rays from Johns-Manville workers — to see if the patterns in human lungs match what he's seeing in mice. And then he writes this sentence: "I hope, before I die, the opportunity may be afforded us."
HOST 2: Before I die.
HOST 1: Before I die. Was he sick? We don't know for certain. What we know is this: on October 24, 1946, LeRoy Upson Gardner died suddenly of a heart attack. He was 57 years old.
HOST 2: Six months after writing "before I die."
HOST 1: The experiment notes? Filed away. The microscope slides. The handwritten observations. The 81.8% figure. All of it — property of the nine companies that had funded the research.
THE HUMAN EVIDENCE
HOST 2: And it wasn't just mice.
HOST 1: No. By 1943, Gardner had documented eleven cases of human lung cancer in Quebec asbestos miners and millers — including two mesotheliomas.
HOST 2: Mesothelioma. In 1943. Seventeen years before the "official" discovery.
HOST 1: Those workers' lungs had been shipped across the border from Johns-Manville facilities in Quebec to Saranac Laboratory.
HOST 2: Shipped. Across the border. By whom?
HOST 1: A lawyer named Ivan Sabourin. General counsel for the Quebec Asbestos Mining Association. According to court documents, Sabourin made repeated trips across the border transporting lung samples and X-rays in the trunk of his car.
HOST 2: A lawyer. Driving dead men's lungs across international borders. In his trunk.
HOST 1: The results went directly to Sabourin. The company doctors who treated the workers were never informed. The families were told their loved ones died from smoking.
HOST 2: And eleven became seventy.
HOST 1: By 1958, the files at Saranac contained over seventy unreported lung cancer cases from Quebec miners. None of the families were ever told the truth.
SPONSOR BREAK 2
HOST 2: When corporations control the science, families never get the truth. Danziger and De Llano has spent thirty years finding the documentation that companies tried to hide — the internal memos, the suppressed studies, the evidence that was never supposed to surface. Dandell.com.
THE SUPPRESSION VOTE - 1947
HOST 1: So Gardner dies in October 1946. Within months, the sponsor companies have a problem: Arthur Vorwald, Gardner's successor, is preparing to publish the research.
HOST 2: The research with the 81.8% cancer rate.
HOST 1: The cancer finding they now owned. So in early 1947 — most sources say January — representatives of the nine funding companies meet. And they make a decision.
HOST 2: Let me guess. They voted.
HOST 1: They voted. The decision, documented in court records from the Sumner Simpson Papers: publication "would not include any objectionable material."
HOST 2: "Objectionable." That's doing a lot of work in that sentence.
HOST 1: Defined as — and I'm quoting — "any relation between asbestos and cancer."
HOST 2: They defined cancer as objectionable. And put it in the minutes.
HOST 1: Vandiver Brown — the same Johns-Manville lawyer who'd received the "less said about asbestos" letter from Sumner Simpson back in 1935 — sent instructions. All references to "cancers and tumors" should be deleted. And Brown asked the sponsors to return their copies of the draft report.
HOST 2: Return the drafts. Because —
HOST 1: Because — and this is Brown's own language — it would be "unwise to have any copies of the draft report outstanding if the final report was to be different in any substantial respect."
HOST 2: They wanted no evidence of what they'd cut. Except they created evidence by writing that down.
THE SANITIZED RECORD
HOST 1: The 1948 report, published two years after Gardner's death, ran 42 pages. It discussed asbestosis in detail. It mentioned that tumors had been observed. And then it promised: "Rather than delay the entire report, further discussion will be reserved for a supplement to be issued later."
HOST 2: The supplement that was definitely coming.
HOST 1: Never published. In 1951, Vorwald and his colleagues published a journal article claiming to present "a complete survey of the entire experimental investigation." The 81.8% figure? Deleted entirely.
HOST 2: "A complete survey." Minus the cancer. That's not a survey. That's a press release.
HOST 1: The sanitized science entered the public record. The truth stayed in the archives.
FIFTY-TWO YEARS
HOST 2: How long did it stay buried?
HOST 1: Fifty-two years. From 1951 to 1995. During that time, workers kept dying. The 1957 meeting we talked about last episode — where the ATI voted not to fund cancer research because it would "stir up a hornet's nest" — that happened six years after the Saranac findings were buried.
HOST 2: They already had proof. They didn't need more research.
HOST 1: They needed silence. And here's a detail that makes it worse. In February 1949 — two years after the suppression decision — five thousand workers in Quebec went on strike.
HOST 2: The asbestos miners. What were they striking for?
HOST 1: One of their demands: elimination of asbestos dust. Another: action to check the spread of lung disease. They were fighting for dust control. They had no idea the companies already possessed proof that the dust caused cancer.
HOST 2: They went on strike two years after the evidence was buried. Fighting without their strongest weapon.
HOST 1: The companies suppressed the cancer evidence in 1947. Two years later, workers struck for better conditions. The strike was declared illegal. Provincial police were dispatched. The workers lost.
SCHEPERS AND THE 1995 REVELATION
HOST 2: So who eventually pulled this out of the filing cabinet?
HOST 1: In 1954, a South African researcher named Gerrit Schepers came to Saranac Laboratory as Director of Research. And he found the files.
HOST 2: Gardner's notes. The slides. The suppression.
HOST 1: All of it. And when Schepers raised what he'd found, he was told to stay quiet. Years later, he described what happened in five words: "I complied thereafter in the United States."
HOST 2: "I complied." That's it?
HOST 1: That's it. He became an expert witness in asbestos litigation. He testified about what the industry knew and when they knew it. But the full account didn't appear in a peer-reviewed journal until 1995.
HOST 2: 1995. Gardner's research finally published — fifty-two years after he wrote it.
HOST 1: The American Journal of Industrial Medicine. Gardner's 81.8% figure. The suppression. The promised supplement that never appeared. All of it, finally in the scientific record.
HOST 2: Fifty-two years. How many workers died in that gap?
HOST 1: Gardner died thinking his research would eventually be published. He wrote "I hope, before I die" — and the opportunity never came.
SPONSOR BREAK 3 — ANNA JACKSON SPOTLIGHT
HOST 2: If you're listening to this because someone you love was diagnosed with mesothelioma, you already know what that waiting feels like. The waiting for answers. The waiting for someone to tell you where the exposure happened and who's responsible.
HOST 1: Paul Danziger and Rod De Llano have spent over thirty years finding the documentation that companies tried to bury. Nearly two billion dollars recovered for asbestos victims. And their team knows this fight personally.
HOST 2: Anna Jackson is Director of Patient Support. Fifteen years ago, she lost her own husband to cancer. She walked away from a career in advertising and joined this fight — because she understood what families go through.
HOST 1: That's who answers when you call. Not a call center. A team where everyone has skin in the game.
HOST 2: Dandell.com. That's D-A-N-D-E-L-L dot com.
HOST 1: The documentation exists. The truth exists. Someone just has to find it.
THE BLUEPRINT
HOST 2: So what does the Saranac story prove?
HOST 1: It's the mechanism. The blueprint for how you purchase silence.
HOST 2: Step one: fund the research.
HOST 1: Step two: own the results.
HOST 2: Step three: bury what you find.
HOST 1: Gardner's scientific caution — his own recommendation to omit the cancer data until he could do it right — was appropriate given the experimental limitations. He wanted to do the work properly. He applied for independent funding to escape the trap.
HOST 2: He was denied. And then he died. And his own integrity became the excuse.
HOST 1: And the companies met. And they voted. And fifty-two years passed before anyone outside the litigation system knew the truth.
NEXT EPISODE TEASE
HOST 2: But there's more.
HOST 1: There's more. The animal studies weren't the only evidence they buried. Next episode, we're going to look at what the industry did with human data — the workers whose lungs ended up at Saranac, and the pattern that emerges when you trace their deaths.
HOST 2: The seventy workers nobody counted.
HOST 1: The seventy workers nobody counted. Episode 23: The Human Experiments.
HOST 2: We'll see you then.
KEY TAKEAWAYS
- The Saranac contract was a blueprint for purchasing scientific silence. Nine asbestos companies funded research at Saranac Laboratory with a clause making all results their "property" and publication contingent on sponsor approval.
- Gardner discovered an 81.8% cancer rate in asbestos-exposed mice in 1943 — 17 years before asbestos-cancer links were "officially" established — but could not publish under his contract.
- Gardner's own scientific integrity became the industry's cover. He recommended omitting cancer from the report pending controlled experiments. After his death, the industry used his caution to justify permanent suppression.
- The NCI denied Gardner's escape route. His $10,000 grant application for controlled experiments was rejected on methodological grounds — trapping him with industry-controlled funding.
- Eleven human mesothelioma and lung cancer cases were documented at Saranac by 1943. Workers' lungs were transported across the U.S.-Canada border by a corporate lawyer. Families were told deaths were from smoking.
- The 1947 suppression vote defined cancer as "objectionable material." Nine companies voted unanimously to delete all cancer references from the report. Brown ordered return of all draft copies.
- Five thousand Quebec miners struck in 1949 for dust control — unaware the companies already possessed proof the dust caused cancer, suppressed two years earlier.
- The full truth was not published until 1995 — 52 years after Gardner's discovery — when Dr. Gerrit Schepers finally published in the American Journal of Industrial Medicine.
FREQUENTLY ASKED QUESTIONS
What was the Saranac Laboratory asbestos coverup?
In 1936, nine asbestos companies funded research at Saranac Laboratory with a contract giving them ownership of all results and veto power over publication. When researcher LeRoy Upson Gardner discovered an 81.8% tumor rate in asbestos-exposed mice in 1943, the companies suppressed the findings. After Gardner's death in 1946, the sponsors voted to delete all cancer references from publications. The full data was not published until 1995 — a 52-year suppression.
Who was LeRoy Upson Gardner?
Dr. LeRoy Upson Gardner (1888-1946) was a Yale-trained pathologist who arrived at Saranac Lake, New York in 1917 as a tuberculosis patient. After recovering, he became director of the Saranac Laboratory. His asbestos experiments yielded critical cancer evidence that the industry suppressed. He died of a heart attack at age 57, six months after writing "I hope, before I die, the opportunity may be afforded us" in a letter requesting access to Johns-Manville worker X-rays.
How did the asbestos industry control scientific research?
The November 20, 1936 contract between nine companies and Saranac Laboratory stated that research results would be the "property of those advancing the required funds" and that publication would only occur "if deemed desirable" by the sponsors. This gave the industry contractual veto power over any findings — including the cancer evidence Gardner discovered.
What happened to Gardner's cancer findings?
After Gardner's death in October 1946, sponsor companies met in January 1947 and voted that publications "would not include any objectionable material" — defined as "any relation between asbestos and cancer." The 1948 report omitted the cancer data, and a 1951 journal article claiming to present "a complete survey" deleted the 81.8% figure entirely. The truth was published in 1995 by Dr. Gerrit Schepers.
What evidence did Gardner find of human asbestos cancer?
By 1943, Gardner had documented 11 cases of lung cancer in Quebec asbestos miners, including 2 mesotheliomas — 17 years before the asbestos-mesothelioma link was "officially" established. Lung samples were transported across the U.S.-Canada border by Ivan Sabourin, corporate counsel for the Quebec Asbestos Mining Association. By 1958, over 70 unreported cases had accumulated in Saranac files. Families were never informed.
