Episode 29 — The Shipyard Generation

Veterans are 6 to 7 percent of the U.S. population. They account for 30 percent of all mesothelioma diagnoses. Navy veterans are 6.47 times more likely to die from mesothelioma than the general population. The average shipyard worker’s latency: 49.4 years. The reason isn’t bad luck. A factory worker goes home at night. A sailor lived inside his exposure — sleeping ten feet from the boiler room, eating in a mess hall surrounded by asbestos-insulated pipes, breathing ship air around the clock for years of service. Over 300 different asbestos-containing products on a single ship.

Episode 29 is the Arc 6 finale. It follows the human cost of five episodes of statistics and corporate memos: three survivors who beat the odds the industry created, the 1977 discovery of the Sumner Simpson Papers that finally proved the cover-up, and the most tragic timing in American medical history — Dr. Irving Selikoff presented definitive proof that asbestos causes mesothelioma in October 1964. Ten weeks after the Gulf of Tonkin Resolution sent 3.4 million more servicemembers toward the most heavily asbestos-insulated ships in the fleet.

Key Takeaways

• The 30 percent problem. Veterans are four times overrepresented in mesothelioma diagnoses because naval service meant continuous exposure — not intermittent. A sailor couldn’t go home at night. He slept, ate, and worked within feet of asbestos-insulated boilers and pipes, twenty-four hours a day, for years. The Navy used over 300 different asbestos-containing products on a single ship. Navy veterans are 6.47 times more likely to die from mesothelioma than the general population. About 1,000 are diagnosed every year.
• The latency math. Average latency for shipyard workers: 49.4 years. Range: 14 to 72 years documented. Only 4 percent of cases appear within 20 years. A third don’t appear until after 40 years. A man exposed at Brooklyn Navy Yard in 1943 at age 22 would not typically receive his diagnosis until the early 1990s — when the executives who made the decisions he worked under were retired or dead, and no one could connect a cough to a pipe he insulated half a century before. That is not a coincidence. That was the calculation.
• Three survivors. Michelle was four years old when she was exposed — just hugging her father when he came home from work, his clothes covered in dust. Diagnosed at ten with peritoneal mesothelioma. Given three to six months. She lived thirty-five years. She adopted four children. She counseled over two hundred families facing the same diagnosis. She never charged a penny. Lannie was a conservation officer in Virginia, exposed through brake linings and gaskets. Diagnosed at sixty-two, given eighteen months. Seventeen years later, he is still here. Icom was a Navy boilerman on USS Kearsarge and USS John A. Bole for ten years — the most dangerous job on any ship. Diagnosed in 2016, he became the first VA patient to receive pleurectomy with decortication surgery. Eight years later: “It’s a beautiful day.”
• The Sumner Simpson Papers, 1977. Litigation in South Carolina forced internal Johns-Manville documents into the open. A 1930 memo titled “Pulmonary Asbestosis.” A 1931 letter from Johns-Manville’s attorney detailing the deliberate four-year delay of a government study. And Sumner Simpson’s 1935 letter: “The less said about asbestos, the better off we are.” Within months, a California congressman featured them in congressional hearings. The Washington Post reported companies had “hid evidence” for more than thirty years. Johns-Manville filed for bankruptcy in August 1982 under 16,000 lawsuits and was removed from the Dow Jones Industrial Average.
• The Manville Trust. Established in 1988 with $2.5 billion. Has since paid out over $5 billion to victims and families. It became the template for the more than 60 asbestos trusts now holding an estimated $30 billion in total assets.
• Selikoff’s timing. August 7, 1964: Gulf of Tonkin Resolution. 88–2 in the Senate. 414–0 in the House. The Vietnam escalation begins. October 19, 1964 — ten weeks later — Selikoff presents at the New York Academy of Sciences: definitive proof that asbestos causes mesothelioma and lung cancer, even at low exposures, even brief exposures. Even wives who only washed their husbands’ work clothes. Peak U.S. asbestos consumption: 803,000 tons in 1973. Three and a half million Vietnam-era servicemembers deployed. Average latency: 49 years. Peak deployment: 1968. 1968 plus 49 years.
• The Vietnam window is now. The peak mortality window for Vietnam-era veterans is today. That’s Arc 7.

Full Transcript

Cold Open: September 1972

Host 1: September 1972. A man sits in a doctor’s office in New York City. He’s 52 years old. He’s got a cough that won’t go away. Shortness of breath. He’s worked thirty years since the war. Raised a family. Bought a house. Watched his kids graduate.

Host 2: Normal life.

Host 1: Normal American life. The doctor shows him the X-ray. There’s something on his lung. It’s called mesothelioma.

Host 2: Had he ever heard of it?

Host 1: Almost no one had. It was so rare that some pathologists doubted it existed. But this doctor, Dr. Irving Selikoff at Mount Sinai, he’d been seeing cases like this for years. And he had a question: Where did you work during the war?

Host 2: Shipyard.

Host 1: Brooklyn Navy Yard. 1943 to 1945. Electrician. The doctor nods. He’s heard this story before. Because in the last year, several cases of mesothelioma linked to World War II have come to his attention.

Host 2: 1943 to 1972. That’s…

Host 1: Almost thirty years.

Host 2: Thirty years of normal life.

Host 1: Thirty years of living with microscopic fibers embedded in his lungs. Waiting.

[Sponsor break]

The 30 Percent

Host 1: Here’s a number you’ve probably heard before. Thirty percent.

Host 2: One in three mesothelioma patients. From a group that’s one in fifteen of the country.

Host 1: Thirty percent. But veterans are only 6 or 7 percent of the U.S. population.

Host 2: That’s a four-fold overrepresentation.

Host 1: About a thousand veterans diagnosed every year. Out of roughly 3,000 total cases. Let me explain why.

Host 2: And nobody in command thought to ask why.

Host 1: Here’s the thing everyone misses about shipyard exposure. A factory worker goes home at night. He breathes clean air for sixteen hours. The fibers in his lungs have time to… not clear, exactly, but his exposure is intermittent.

Host 2: But a sailor…

Host 1: A sailor sleeps ten feet from the boiler room. A sailor eats in a mess hall surrounded by asbestos-insulated pipes. A sailor breathes ship air twenty-four hours a day, seven days a week, for years.

Host 2: So it’s not just that they were exposed. It’s that they were never not exposed.

Host 1: For the entire duration of their service. And the Navy used more asbestos than any other branch. Every pipe. Every boiler. Every turbine. Over 300 different asbestos-containing products on a single ship.

Host 2: That’s not bad luck. That’s engineering.

Host 1: It was engineering. It was the most efficient insulation available. Navy veterans are 6.47 times more likely to die from mesothelioma than the general population. 6.47 times.

Host 2: And the latency?

Host 1: Average latency for shipyard workers: 49.4 years. Range: 14 to 72 years documented. Only 4 percent of cases show up within 20 years. A third of cases don’t appear until after 40 years.

Host 2: So the WWII generation…

Host 1: Their peak mortality window was the 1990s and 2000s. Most of those workers have already died. But with latency stretching up to 72 years, cases are still appearing today. And the Vietnam generation? They’re just hitting their peak now.

Host 2: So when we say veterans are 30 percent of mesothelioma cases…

Host 1: We’re not describing bad luck. We’re describing the predictable outcome of decisions made in the 1930s and 40s. They knew it was dangerous. They exposed millions anyway. And forty, fifty, sixty years later, those decisions are still killing people.

Host 2: Is there an end date to this?

Host 1: Today. Right now. Let me introduce you to some of them.

[Sponsor break — Beating the Odds book]

The Survivors: Michelle, Lannie, Icom

Host 1: For the next few minutes, I want to set aside the statistics. The corporate memos. The suppression. I want to tell you about three people who were supposed to die… and didn’t.

Host 2: What did surviving actually look like for them?

Host 1: Michelle was four years old when she was exposed. Her father worked with asbestos. Every day, he came home and she ran to hug him. His work clothes covered in dust. Microscopic fibers.

Host 2: She never worked with asbestos. She just hugged her father.

Host 1: She was diagnosed at ten. 1980. Peritoneal mesothelioma — that’s the abdomen, not the lungs. Doctors gave her three to six months.

Host 2: At ten years old.

Host 1: She lived thirty-five years. She raised a son. She adopted four children. She counseled over two hundred families who’d just gotten the same diagnosis she got. For thirty-five years, she was living proof that survival was possible.

Host 2: What happened?

Host 1: She passed in 2015. Age forty-four. After three and a half decades of a life she was never supposed to have.

Host 2: [Quietly] Thirty-five years after a three-month prognosis.

Host 1: Lannie wasn’t a shipyard worker. He wasn’t a boilerman or a pipefitter. He was a conservation officer in Virginia.

Host 2: Wait, how does a conservation officer get exposed?

Host 1: Brake linings. Gaskets. Insulation in vehicles and equipment. The asbestos got everywhere, into jobs nobody thought of as asbestos occupations.

Host 2: So he didn’t even know he’d been exposed.

Host 1: Not until the diagnosis. 2007. Age sixty-two. They gave him eighteen months without surgery.

Host 2: What did he do?

Host 1: As of our research… seventeen years later… he’s still here. His wife Linda, a nurse for thirty years, wrote a book about their journey. They’ve spent nearly two decades doing what doctors said was impossible.

Host 2: Seventeen years.

Host 1: And then there’s Icom. Navy boilerman for ten years. USS Kearsarge. USS John A. Bole. The job we just talked about — the most dangerous job on any ship.

Host 2: The most dangerous job on the ship. And he volunteered for it for ten years.

Host 1: He was diagnosed in 2016. And here’s what makes his story remarkable: he became the first VA patient to receive a cutting-edge surgical protocol called pleurectomy with decortication. P/D. The VA was pioneering treatment, and Icom was the first through the door.

Host 2: Eight years later?

Host 1: Still here. Still greeting everyone he meets with the same phrase: “It’s a beautiful day.”

Host 2: It is.

Host 1: Michelle. Lannie. Icom. Three survivors out of thousands who didn’t survive. Three people who beat the odds that the asbestos industry created.

Host 2: The industry that knew.

Arc 6: The Verdict

Host 1: Let’s remember what they knew. Let’s bind together everything we’ve covered in Arc 6.

Host 2: Five episodes. 1939 to 1960.

Host 1: Here’s the story in one sentence…

Host 2: They knew.

Host 1: They knew it was killing people. They exposed 4.5 million shipyard workers anyway. And when the war ended, they didn’t stop. They expanded.

Host 2: Episode 25. The Navy’s demand.

Host 1: June 1940: 168,000 shipyard workers. December 1943: 1.7 million. The Stephenson memo: “Health inspections would disturb labor element.”

Host 2: Episode 26. The conditions.

Host 1: Twenty-four hour production. Three shifts. Dust so thick workers couldn’t see across the room. Howard Zinn, the historian, started as an apprentice at Brooklyn Navy Yard. Before he became one of America’s most famous historians, he was a nineteen-year-old kid breathing asbestos dust.

Host 2: Episode 27. The women.

Host 1: 6.48 percent of the workforce in 1942. By war’s end: 13.3 percent. Lucille Kolkin. Tack welder. Brooklyn Navy Yard. And the wives, exposed just from washing their husbands’ clothes.

Host 2: Episode 28. The betrayal.

Host 1: September 1945: war ends. Asbestos production should decline. Instead: 343,000 tons in 1945. 709,000 tons in 1955. A 107 percent increase. In peacetime. The 1947 ATI vote: six to two against studying the cancer link. “Stir up a hornet’s nest.” Forty million homes. Floor tiles, joint compound, popcorn ceilings. Three thousand products by 1958.

Host 2: They knew. They suppressed. They expanded. They waited.

Host 1: And here’s the math. They knew by 1930 that asbestos caused disease. By 1943, they knew it caused cancer. They had animal studies showing 81.8 percent tumor rates. They had the Sumner Simpson Papers. They had the Saranac suppression. And they looked at 4.5 million shipyard workers and they did the math…

Host 2: How long until anyone connects the dots?

Host 1: Thirty years. Forty years. Fifty years. By the time workers started dying, the executives who made those decisions would be retired. Or dead. The workers would be grandfathers. And no one could connect a cough in 1972 to a pipe insulated in 1943.

Host 2: The perfect crime.

Host 1: Almost. Because in 1977, someone found the documents.

[Sponsor break — document discovery context]

The Sumner Simpson Papers

Host 1: 1977. Litigation in South Carolina forces something into the open. Internal Johns-Manville documents going back to the 1930s.

Host 2: The Sumner Simpson Papers.

Host 1: A 1930 memo titled “Pulmonary Asbestosis.” A 1931 letter from Johns-Manville’s attorney explaining changes that delayed a government study by four years. A 1935 letter from Sumner Simpson himself: “The less said about asbestos, the better off we are.”

Host 2: 1935.

Host 1: 1935. And the documents were discovered in 1977. No protective order stopped them from going public. Within months, a California congressman featured them in congressional hearings. The Washington Post reported: “Documents uncovered in a series of recent lawsuits indicate that for more than three decades the nation’s largest asbestos companies hid evidence.”

Host 2: Where had it been all that time?

Host 1: The truth was always there. Buried in filing cabinets. Waiting.

Host 2: And the impact?

Host 1: Johns-Manville filed for bankruptcy in August 1982. Sixteen thousand lawsuits. They were removed from the Dow Jones Industrial Average.

Host 2: What happened to the victims who’d been waiting on compensation?

Host 1: The Manville Trust was established in 1988 with two and a half billion dollars. To date, it’s paid out over five billion to victims and families.

Host 2: Five billion dollars in guilt.

Selikoff and the Terrible Timing

Host 1: The document discovery proved what we’ve been documenting in this series: they knew. They suppressed. They calculated. But there was one more piece of the story. The doctor who sounded the alarm.

Host 2: Selikoff.

Host 1: Irving Selikoff. And the timing of his discovery is one of the cruelest ironies in American medical history.

Host 2: What do you mean?

Host 1: August 7, 1964. The Gulf of Tonkin Resolution passes Congress. 88 to 2 in the Senate. 414 to 0 in the House. President Johnson signs it into law three days later.

Host 2: The Vietnam escalation begins.

Host 1: October 19, 1964. Eight weeks later. Dr. Irving Selikoff organizes a conference at the New York Academy of Sciences. “The Biological Effects of Asbestos.”

Host 2: Wait… two months?

Host 1: Two months. The conference where Selikoff presented definitive proof that asbestos causes mesothelioma and lung cancer. Even brief exposure. Even low doses. The same conference where researchers presented evidence that wives could develop mesothelioma just from washing their husbands’ work clothes.

Host 2: So science proved the danger…

Host 1: Just as the largest military escalation since World War II began.

Host 2: Who was Selikoff?

Host 1: An unlikely crusader. Born in Brooklyn, 1915. Jewish kid who couldn’t get into American medical schools. Quotas kept him out. He had to study abroad, in Scotland and Australia. He came back, worked at Mount Sinai, co-discovered the tuberculosis treatment isoniazid, won the Lasker Award — the “American Nobel.” And then something changed. The Asbestos Workers Union asked him to add their membership to his clinic practice.

Host 2: And he started seeing patterns.

Host 1: Workers dying. Cancer at rates that made no sense. Of seventeen workers he initially identified with concerning cases, fifteen were dead within a few years. He started systematic examinations. His study examined 632 asbestos insulation workers who’d entered the trade before 1943.

Host 2: What did he find?

Host 1: Forty-five died of lung or pleural cancer. Expected number? 6.6. A 6.8-fold increase. Four mesotheliomas out of 255 deaths. An exceedingly high incidence for such a rare tumor.

Host 2: And this was 1964.

Host 1: And the Vietnam War was about to expose 3.4 million more servicemembers to asbestos on ships, in aircraft, on bases. Peak U.S. asbestos consumption: 1964 to 1975. Over 700,000 tons annually. All-time high: 803,000 tons in 1973.

Host 2: While the science was proving it killed people.

Host 1: While the science was proving it killed people.

Host 2: So what happened?

Host 1: The industry suppressed his findings. Tried to discredit him. Accused him of exaggeration. And while they were attacking him, another generation was being exposed.

Host 2: How many more people does that mean?

Host 1: 9 million total Vietnam-era veterans. 3.4 million in the Southeast Asia theater. Peak military asbestos use: 1964 to 1975. The Navy stopped using asbestos in the mid-1970s. But by then…

Host 2: The exposure had already happened.

Host 1: And those veterans are dying now. Average latency: 49 years. Peak deployment: 1968. Add 49 years.

Host 2: 2017.

Host 1: We’re in the peak mortality window. Right now. Today. That’s Arc 7.

[Closing sponsor break — veterans and shipyard workers]

Structured Q&A

Why do veterans make up 30% of all mesothelioma diagnoses?

Veterans are 6 to 7 percent of the U.S. population but account for 30 percent of all mesothelioma diagnoses — a four-fold overrepresentation driven by the continuous nature of military asbestos exposure, particularly in the Navy. A factory worker goes home at night and breathes clean air for sixteen hours. A sailor slept ten feet from the boiler room, ate in a mess hall surrounded by asbestos-insulated pipes, and breathed ship air around the clock, seven days a week, for years of service. The Navy used over 300 different asbestos-containing products on a single ship. Navy veterans are 6.47 times more likely to die from mesothelioma than the general population. Approximately 1,000 veterans are diagnosed each year.

What was the average latency period for shipyard workers with mesothelioma?

The average latency period for shipyard workers is 49.4 years, with a documented range from 14 to 72 years. Only 4 percent of cases appear within 20 years of exposure. One third of cases don’t appear until more than 40 years after exposure. A worker exposed at Brooklyn Navy Yard in 1943 at age 22 would not typically develop symptoms until around 1993. Vietnam-era veterans, exposed during peak U.S. asbestos consumption from 1964 to 1975, are entering their peak mortality window now.

Who were the three mesothelioma survivors profiled in this episode?

Michelle was diagnosed at age 10 with peritoneal mesothelioma after secondary exposure from hugging her father when he came home from work. Given 3 to 6 months to live in 1980, she survived 35 years — raising a son, adopting four children, and counseling over 200 families facing the same diagnosis before passing in 2015 at age 44. Lannie, a conservation officer in Virginia exposed through brake linings and vehicle gaskets, was diagnosed at 62 and given 18 months. He is more than 17 years past that prognosis. His wife Linda, a nurse for 30 years, wrote a book about their journey. Icom, a Navy boilerman on USS Kearsarge and USS John A. Bole, was diagnosed in 2016 and became the first VA patient to receive pleurectomy with decortication surgery. Eight years later, his daily greeting is still: “It’s a beautiful day.”

What did Irving Selikoff’s 1964 study find about asbestos workers?

Dr. Irving Selikoff examined 632 asbestos insulation workers who had entered the trade before 1943. Among 255 deaths in the group, 45 were from lung or pleural cancer — where only 6.6 were expected, a 6.8-fold excess. There were also 4 mesotheliomas, an exceedingly high rate for a tumor so rare that some pathologists doubted its existence. Selikoff presented these findings in October 1964 — just two months after the Gulf of Tonkin Resolution began the Vietnam escalation that would expose another 3.4 million servicemembers to asbestos. Peak U.S. asbestos consumption: 803,000 tons in 1973, at the height of military use.

What were the Sumner Simpson Papers and why did they matter?

The Sumner Simpson Papers are internal Johns-Manville documents spanning the 1930s through the 1950s, forced into the open by litigation in South Carolina in 1977. They included a 1930 memo titled “Pulmonary Asbestosis,” a 1931 letter from Johns-Manville’s attorney explaining the deliberate four-year delay of a government study, and Sumner Simpson’s 1935 letter stating “the less said about asbestos, the better off we are.” These documents proved the industry had known about asbestos’s lethal effects for decades before workers began dying. A California congressman featured them in congressional hearings within months. The Washington Post reported that companies had “hid evidence” for more than thirty years. Johns-Manville filed for bankruptcy in August 1982 under 16,000 lawsuits.

How did the Gulf of Tonkin timing make the Vietnam asbestos exposure worse?

On August 7, 1964, Congress passed the Gulf of Tonkin Resolution, authorizing the Vietnam military escalation. On October 19, 1964 — just ten weeks later — Dr. Irving Selikoff presented definitive proof at the New York Academy of Sciences that asbestos causes mesothelioma and lung cancer, even at low and brief exposures. Science proved the danger just as the largest military mobilization since WWII began. Peak U.S. asbestos consumption occurred from 1964 to 1975 — 803,000 tons in 1973 alone. The Navy stopped using asbestos in the mid-1970s, but by then 3.4 million Vietnam-era servicemembers had been exposed. With 49-year average latency, their peak mortality window is now.
