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.

Asbestos: A Conspiracy 4,500 Years in the Making
Episode 24: The Paper Trail
Use Left/Right to seek, Home/End to jump to start or end. Hold shift to jump forward or backward.
In a locked safe at Raybestos-Manhattan Corporation headquarters in Stratford, Connecticut, approximately 6,000 documents sat undisturbed for forty-four years. They were filed alphabetically under a single label: DUST.
Episodes 20 through 23 documented what the asbestos industry did. Episode 24 — the Arc Five finale — proves it. Not through reconstruction or inference. Through the actual letters, internal memos, scientific studies, and federal court testimony that these companies wrote, signed, carbon-copied, and filed — believing no one outside the boardroom would ever read them. They used standard 1930s business practices. That’s what preserved the evidence of their own conspiracy.
Key Takeaways
- 1933 — The first asbestos lawsuit is settled and silenced. Eleven workers sue Johns-Manville Corporation in New Jersey for failing to provide ventilation and safety equipment. Settlement: $30,000 total — $2,700 per worker. Conditions: their attorney agrees never to file another asbestos case, and the terms stay confidential. Internal Johns-Manville meeting minutes the same year: “Our past policy of keeping this matter confidential is to be pursued.”
- 11 human lung cancer cases from Quebec asbestos miners — including 2 mesotheliomas. Gardner dies in 1946 before publishing. At a January 1947 industry meeting, companies agree that “the reference to cancer and tumors should be deleted.” Brown documents his own instructions: “All references to cancers and tumors deleted.”
- 1949 — The Smith memo: don’t tell the workers. Dr. Kenneth Smith, a Johns-Manville physician, recommends that workers with early asbestosis visible on chest X-rays “should not be told of his condition so that he can live and work in peace, and the company can benefit by his many years of experience.”
- April 25, 1984 — The federal court testimony. Johns-Manville Corporation v. The United States of America. Former Unarco employee Charles Roemer testifies that at a c. 1942–1943 meeting, he asked Vandiver Brown whether the company would really let sick workers keep working until they died. Brown’s response: “Yes. We save a lot of money that way.”

Episode 24: The Paper Trail
Asbestos: A Conspiracy 4,500 Years in the Making — Arc 5 Finale: The Conspiracy Begins
Hosts: Host 1 (narrator) and Host 2 (co-host). This episode covers the period 1933–1943 and focuses on internal corporate documents — letters, memos, scientific studies, and suppression strategies — preserved in a corporate vault and later used as evidence of conspiracy.
The Vault
Host 1: Stratford, Connecticut. Raybestos-Manhattan Corporation headquarters. Somewhere in the executive offices, there's a personal safe.
Host 2: What's in it?
Host 1: Heavy combination lock. Access limited to a handful of people. Inside: approximately six thousand documents.
Host 2: How long had they been accumulating?
Host 1: Two decades of correspondence. Internal memos. Meeting notes. Scientific reports. All filed together under a single label.
Host 2: What's the label?
Host 1: DUST.
Host 2: They labeled it "DUST."
Host 1: D-U-S-T. Filed alphabetically. Right there with "Development" and "Distribution."
Host 2: That's not subtle.
Host 1: It's not meant to be subtle. It's meant to be accurate. The vault belonged to Sumner Simpson, President of Raybestos-Manhattan since its founding in 1929. And between 1933 and 1943, Simpson and his counterparts at other companies created a paper trail.
Host 2: What kind of paper trail?
Host 1: Letters. Memos. Study results. Suppression strategies. All preserved using standard 1930s business practices.
Host 2: Why does the medium matter? What's significant about paper documentation specifically?
Host 1: Carbon copies. Heavyweight bond paper. Corporate letterhead. Signed in ink. Because they used standard 1930s practices, every letter made at least one duplicate. Every memo was preserved for filing. Everything a businessman was supposed to keep — they kept. Including the evidence of their own conspiracy.
Host 2: They thought it was all just routine business correspondence.
Host 1: For forty-four years, they were right. But eventually the vault opens. And what's inside becomes evidence. This is Episode 24: The Paper Trail.
The 1933 Settlements and the Lanza Study
Host 1: 1933. Eleven asbestos workers file a negligence lawsuit against Johns-Manville Corporation in New Jersey.
Host 2: What are they claiming?
Host 1: The company failed to provide adequate safety equipment. Proper ventilation. Working masks.
Host 2: How does it resolve?
Host 1: Johns-Manville settles. Thirty thousand dollars total.
Host 2: For eleven people.
Host 1: Twenty-seven hundred dollars per worker. Two conditions. One: the lawyer who brought the cases agrees not to file any more. Condition two: the terms stay confidential.
Host 2: Totally normal settlement behavior.
Host 1: And Johns-Manville's internal meeting minutes from 1933 confirm the strategy.
"Our past policy of keeping this matter confidential is to be pursued."
— Johns-Manville Corporation internal meeting minutes, 1933
Host 1: Same year — 1933 — Johns-Manville and Raybestos-Manhattan fund a study by Doctor Anthony Lanza.
Host 2: Lanza. MetLife's man. The one who struck "result fatally" from his own study.
Host 1: The same. And in 1931, his preliminary findings showed that eighty-seven percent of workers with more than fifteen years of asbestos exposure had radiographic evidence of lung disease.
Host 2: That's nine out of every ten long-term workers.
Host 1: Right. Vandiver Brown — Johns-Manville's general counsel, vice president, corporate secretary — writes to Lanza in late 1933. Requests changes. The published version needs to minimize the danger. And it works. Lanza's original draft said:
"It is possible for uncomplicated asbestosis to result fatally."
— Dr. Anthony Lanza, original draft (suppressed)
Host 2: And the published version?
Host 1: February 1936. Journal of the American Medical Association.
Asbestosis "did not result in any marked disability."
— Published version, JAMA, February 1936
Host 2: Four-year delay between completion and publication. Why hold it that long?
Host 1: Johns-Manville plans to use the altered study as a lobbying tool to prevent asbestosis from being added to New Jersey's workers' compensation law.
Host 2: Did it work?
Host 1: New Jersey didn't recognize asbestosis as compensable until 1945. Ten-year delay.
Host 2: And he wrote all of this down.
Host 1: In company memos. Filed for reference. Also 1933: Lanza writes to a Johns-Manville doctor in Waukegan — tells him not to post warning signs for workers.
"Because of the extraordinary legal situation."
— Dr. Anthony Lanza, letter to Johns-Manville doctor, 1933
Host 1: And in 1936, Lanza assures Sumner Simpson that Doctor R.R. Sayers can be
"Relied upon not to disclose findings of asbestosis to the workers."
— Dr. Anthony Lanza, letter to Sumner Simpson, 1936
Host 2: Who's Sayers?
Host 1: Lanza's former colleague at the U.S. Public Health Service.
The British Report and the Systematic Suppression of American Reprints
Host 2: How organized is this? A few letters — or something more systematic?
Host 1: Systematic. Companies, insurance providers, government agencies — all coordinating. All documenting the coordination in writing. By 1935, the American asbestos industry has a specific problem.
Host 2: What kind of problem?
Host 1: The British have gone public. The Merewether and Price Report. 1930. British government study of three hundred sixty-three asbestos workers. Twenty-five percent had asbestosis.
Host 2: And eighty percent of workers with more than twenty years exposure?
Host 1: Were affected. The report was published simultaneously in American industrial medical journals. American doctors, regulators, workers' compensation boards could read it. The British weren't hiding anything. In March 1932, the UK implemented the first asbestos-specific regulations in the world. Required dust control, ventilation, medical examinations.
Host 2: What could American companies do about a British government report?
Host 1: They couldn't stop British publications from crossing the Atlantic. All they could do was control American reprints.
The Rossiter Letter
Host 1: September 25th, 1935. Sumner Simpson receives a letter from A.F. Rossiter — editor and publisher of Asbestos magazine, the American trade publication.
"You may recall that we have written you on several occasions concerning the publishing of information, or discussion of, asbestosis. Always you have requested that for certain obvious reasons we publish nothing, and, naturally your wishes have been respected."
— A.F. Rossiter, editor of Asbestos magazine, to Sumner Simpson, September 25, 1935
Host 2: Rossiter just states it. Flat out.
Host 1: Flat out. On letterhead. Signed. Filed under "DUST." Then Rossiter makes a suggestion: maybe publish a positive article about the industry's dust reduction efforts? Counter the "undesirable publicity" appearing in newspapers?
Host 2: What does having Simpson's reply in writing add to what we already know he believed?
Host 1: A document isn't testimony. It doesn't depend on anyone's memory. Six days later — October 1st, 1935 — Simpson writes to Vandiver Brown at Johns-Manville.
"I think the less said about asbestos, the better off we are."
— Sumner Simpson, President of Raybestos-Manhattan, to Vandiver Brown, October 1, 1935
Host 2: There it is.
Host 1: Eight words. Typed on Raybestos-Manhattan letterhead. Carbon copy filed in Simpson's vault under "DUST." Simpson continues:
"The magazine 'Asbestos' is in business to publish articles affecting the trade and they have been very decent about not re-printing the English articles."
— Sumner Simpson to Vandiver Brown, October 1, 1935
Host 2: What does "very decent" tell us about the arrangement?
Host 1: That the magazine knew it was being managed. "Very decent" is the language you use when someone cooperates willingly. Two days later — October 3rd — Vandiver Brown replies.
Host 2: We have Brown's letter too.
"I quite agree with you that our interests are best served by having asbestosis receive the minimum of publicity."
— Vandiver Brown, Vice President and General Counsel, Johns-Manville, to Sumner Simpson, October 3, 1935
Host 2: Not accurate publicity. Not balanced publicity.
Host 1: Minimum. Brown goes on to suggest that if they do eventually allow publication, they should use American data rather than English data. Because American asbestos dust is, quote, "considerably milder" in North America.
Host 2: The patriotic asbestos.
Host 1: Totally baseless claim, but it's in writing. There's also a Brown letter about occupational disease legislation from this period — dated January 1935 in one source, placed later in others. Exact dating on some of these documents is contested. Forty-four years in a vault, referenced in later correspondence without clear timestamps — the record gets murky.
Host 2: The paper trail was never meant to be read.
Host 1: Which is part of why reconstructing it is a mess. What isn't contested is the content.
"The strongest bulwark against future disaster for the industry is the enactment of properly drawn occupational-disease legislation." It would "eliminate the jury and empower a Medical Board to pass upon existence of disease. It would eliminate the shyster lawyer and the quack doctor since fees would be strictly limited by law. It would permit correcting of initial mistakes in awards by providing hearings to reduce or eliminate awards if claimant not disabled."
— Vandiver Brown, Johns-Manville, letter on occupational disease legislation, c. 1935
Host 2: "Shyster." Worth pausing on that word. The origin is disputed — but for generations it's been used as a dog whistle against Jewish lawyers. Brown puts it in a corporate memo, without hesitation, to describe the people who might hold him accountable.
Host 1: The lawyer representing sick workers. That's the threat Brown is naming. And he puts it in writing.
Host 2: So: no juries, capped fees, company-controlled medical boards, and the ability to reduce payments later.
Host 1: That's the "strongest bulwark." And it's in writing.
The Gardner Coverup: Saranac Laboratory and Cancer Suppression
Host 1: 1936. Multiple asbestos companies jointly fund research at the Saranac Laboratory for Research on Tuberculosis in the Adirondack Mountains. The catch is in the contract.
"Research had to be vetted by company officials prior to publication."
— Saranac Laboratory research contract, 1936
Host 2: They're paying for the right to suppress.
Host 1: They're institutionalizing suppression. The lab's director, Doctor LeRoy Gardner, needs funding — the Great Depression has dried up non-profit money. Industry becomes the major donor. By 1942 to 1943, Gardner has induced malignant tumors in miceusing chrysotile asbestos fibers. He's also documented eleven human lung cancer cases from Quebec asbestos miners — including two mesotheliomas.
Host 2: What did Gardner do with those findings?
Host 1: In 1943, he provides detailed results to Johns-Manville Corporation. Vandiver Brown receives the findings. Gardner tries to obtain independent funding to break free of industry control. Fails. Dies in 1946 before publishing.
Host 2: What did the companies do once Gardner was dead?
Host 1: They hold a meeting. January 1947. They decide:
"There would be no publication of the research of experiments without the group's consent. Publications would not include any objectionable material." And: "any relation between asbestos and cancer." Final agreement: "the reference to cancer and tumors should be deleted."
— Industry meeting minutes, January 1947
Host 2: They're editing a dead man's research.
Host 1: And Vandiver Brown is orchestrating it.
"All references to cancers and tumors deleted."
— Vandiver Brown, Johns-Manville
Host 1: He feels it is
"Unwise to have any copies of the draft report outstanding if the final report was to be different in any substantial respect."
— Vandiver Brown, Johns-Manville
Host 1: He documented his own instructions to suppress.
Host 1: 1941. Vandiver Brown writes to Sumner Simpson about a book review that links asbestos to pneumoconiosis. Brown expresses confidence that the editor of Asbestos magazine will "omit any review of the book in question." Then adds:
"I felt there was considerable likelihood that a number of subscribers would dislike an article on this subject in the trade magazine of the asbestos industry. I had in mind the ostrich-like attitude which has been evidenced from time to time by members of the industry."
— Vandiver Brown to Sumner Simpson, 1941
Host 2: Wait. He's criticizing the ostrich-like attitude?
Host 1: He's criticizing companies that aren't suppressing information effectively enough.
Host 2: The ostrich-like attitude isn't denying danger.
Host 1: It's not coordinating suppression well enough. And he writes it down. Typed. Carbon copied. Filed.
The Roemer Testimony: "We Save a Lot of Money That Way"
Host 1: 1942 or 1943. A meeting takes place between Johns-Manville executives and officials from Unarco — Union Asbestos and Rubber Company. We know from testimony. April 25th, 1984. Federal court. "Johns-Manville Corporation versus The United States of America." Charles Roemer, a Unarco employee who was present, testifies forty years later. Present: Lewis Brown, Johns-Manville's president. Vandiver Brown, the company's attorney and vice president. Not brothers, despite what some sources claim.
Host 2: Unarco was telling sick workers about their diagnoses.
Host 1: Which Johns-Manville saw as stupidity. And Roemer testified:
"I'll never forget, I turned to Mister Brown — and I said, Mister Brown, do you mean to tell me you would let them work until they dropped dead?"
— Charles Roemer, testifying about c. 1942–1943 meeting, federal court, April 25, 1984
Host 2: And we know what he said.
"Yes. We save a lot of money that way."
— Vandiver Brown, Johns-Manville Corporation, c. 1942–1943 (as testified by Charles Roemer, 1984)
Host 2: We save a lot of money that way.
Host 1: A decade of correspondence. Dozens of memos. Scientific studies. Lobbying strategies. And the oral admission — the thing Vandiver Brown said in a room, thinking it would never be repeated — distills it all.
Host 2: Let them work until they drop dead.
Host 1: Because it saves money. Same year — 1943 — Doctor Gardner provides his detailed cancer findings to Johns-Manville. Asbestos causes tumors in mice. Eleven human lung cancer cases, including two mesotheliomas, from asbestos workers.
Host 2: They had proof asbestos caused cancer in 1943.
Host 1: They had proof. They buried it. And they documented the burial.
The Smith Memos: Knowing and Not Telling
Host 1: 1949 — Doctor Kenneth Smith, a physician working with Johns-Manville, sends a memo to company headquarters. Seven mill workers have chest X-rays showing early asbestosis. His recommendation:
"As long as the man is not disabled, it is felt that he should not be told of his condition so that he can live and work in peace, and the company can benefit by his many years of experience."
— Dr. Kenneth Smith, memo to Johns-Manville headquarters, 1949
Host 2: And three years later — Smith recommends warning labels on the product itself?
Host 1: 1952. Smith is now medical director of all Johns-Manville companies. He recommends warning labels on asbestos products. Management rejects it. A "business decision." Warning labels would "cut into sales."
Host 2: Don't tell the workers. Don't label the product. Promote the man who said both.
Host 1: They hire Smith as medical director. They're institutionalizing it.
Arc Five Recap: Sumner Simpson and the Legacy of the Vault
Host 1: May 5th, 1927. Sumner Simpson co-founds the University of Bridgeport in Connecticut.
Host 2: Eight years before the "less said about asbestos" letter.
Host 1: Same man. One of three founding patrons — expanding educational access, building something meant to serve the community for generations.
Host 2: How do you hold both?
Host 1: I don't know. Simpson genuinely believed in spreading knowledge. He funded a university. But when it came to knowledge that threatened profits — knowledge that could save workers' lives — he coordinated suppression. He did good things. He also did this. And the vault — the six thousand documents he preserved — testament to both. The meticulous record-keeping of a businessman who took his work seriously. Including the work of hiding the truth.
Host 2: He filed it under "DUST." Right between Development and Distribution.
Host 1: The most accurate filing label in corporate history. He died in 1953, seventy-nine years old. The vault passed to his son. For twenty-four more years — 1953 to 1977 — those documents sat there while workers kept getting sick, kept dying, kept being told nothing. Perfectly preserved.
Host 2: They thought no one would ever read it.
Host 1: For forty-four years, they were right.
