Episode Summary

Special Episode 00S examines asbestos production during World War II as essential military materiel, establishing the foundational context for subsequent episodes on occupational exposure and corporate knowledge suppression. The episode documents the "Arsenal of Democracy" production mobilization (1940-1945), demonstrating that asbestos was genuinely necessary and technologically irreplaceable for military applications (naval ship insulation, proximity fuze tubes, fireproofing systems). Simultaneously, the episode reveals that industry executives possessed knowledge of asbestos hazards as early as 1918 (insurance industry) and 1935-1945 (Saranac Laboratory animal studies, industry internal memos). The 1943 Army-Navy "E" Award ceremony honoring Keasbey & Mattison for outstanding war production serves as symbolic narrative turning point: workers believing they are serving their country; executives simultaneously suppressing cancer research, implementing nondisclosure policies for diagnosed workers, and planning continued commercial marketing of asbestos products. The episode establishes the "dual truth" framework central to the series' analytical approach: asbestos service to military objectives was genuine AND corporate knowledge suppression and profit prioritization over worker health was equally documented. The episode sets narrative stage for Arc 6 (Burying the Bodies), covering 1.7 million wartime workers' subsequent disease manifestation 20-50 years post-exposure.

COLD OPEN - THE VACUUM TUBES

HOST 1: Before we begin, I want to tell you about something I collect. Vacuum tubes. Old ones. The kind that powered radios and radar and the first computers. Most of mine were made in World War II.

HOST 2: Of course you collect vacuum tubes.

HOST 1: This one's a 1943 Sylvania 6SN7GT. The "Bad Boy" variant. Bottom-gettered, chrome dome. Audiophiles call these the holy grail for preamp stages. Wartime production runs had tighter tolerances than anything made after. Military specs.

HOST 2: And people pay real money for these.

HOST 1: New old stock. Eighty years later, plug it into an amplifier and it lights up. Does exactly what it was designed to do.

HOST 2: Which is?

HOST 1: Blast Creedence Clearwater Revival on vinyl so loud it rattles the neighbors' walls. Zero distortion from my speakers.

HOST 2: Vinyl. Tubes. Let me guess—you've got opinions about speaker wire too.

HOST 1: Oxygen-free copper. American-made. Don't get me started.

HOST 2: I won't.

HOST 1: Here's where I'm going with this. Asbestos was mass-produced the same way. Same factories. Same urgency. Same government contracts. Same patriotic workers.

HOST 2: Same time capsule.

HOST 1: Exactly. Except my tubes don't kill me forty years later. And if they did, I'd want to know.

HOST 2: The prosecution is about to grant the defense its best argument.

HOST 1: That's exactly what we're doing. Before we can understand the betrayal, and it was a betrayal, we have to understand the service. This is a special episode of Asbestos: A Conspiracy 4,500 Years in the Making. This is The Magic Mineral at War.

KEY CONCEPT - DUAL TRUTH NARRATIVE:

Definition: Historical events containing simultaneously true and contradictory elements (genuine military service + deliberate hazard concealment)
Context: WWII asbestos production provided essential war materiel; manufacturers simultaneously suppressed evidence of deadly hazards
Ethical implications: Workers' genuine patriotic service made executive silence and knowledge suppression constitute betrayal rather than simple negligence
Narrative structure: Understanding the service (why asbestos was essential) enables comprehension of why the coverup (executive knowledge combined with silence) represents criminal deception

SEGMENT 1: CONTEXT FOR THE ARSENAL OF DEMOCRACY

HOST 1: December 29th, 1940. Seventy-five million Americans gathered around radios.

HOST 2: Seventy-five million.

HOST 1: Nearly sixty percent of the country. Franklin Roosevelt's sixteenth fireside chat. He opened with a question most Americans were afraid to ask: How real is the threat to American security?

HOST 2: And his answer?

HOST 1: We must be the great arsenal of democracy. For us this is an emergency as serious as war itself.

HOST 2: Before Pearl Harbor.

HOST 1: Eleven months before Pearl Harbor. And then he made a promise. American orders given today will produce results in war power beyond anything which has been seen or foreseen in the dictator states.

HOST 2: That's a bold claim.

NAMED ENTITY - FRANKLIN D. ROOSEVELT FIRESIDE CHAT (DECEMBER 29, 1940):

Date: December 29, 1940
Official name: Sixteenth Fireside Chat
Audience: ~75 million Americans (~60% of U.S. population); radio broadcast
Historical context: 11 months before Pearl Harbor (December 7, 1941)
Key themes: "Arsenal of Democracy"; emergency war production mobilization; Lend-Lease program justification
Rhetorical framing: Crisis as equivalent to wartime; civilian production as patriotic duty
Stated objective: American industrial output to exceed Axis production capacity

HOST 1: Here's what that looked like. American automobile production in 1941: three million cars. American automobile production in 1942: one hundred thirty-nine.

HOST 2: Wait, one hundred thirty-nine cars?

HOST 1: Total. For the year. Ford's Willow Run plant, which had been making sedans, started producing one B-24 bomber every sixty-three minutes. Twenty-four hours a day.

HOST 2: How many shipyard workers before the buildup?

HOST 1: June 1940: one hundred sixty-eight thousand. December 1943: one million, seven hundred thousand. The largest industrial workforce America had ever assembled.

HOST 2: Ten times.

HOST 1: Ten times in three and a half years. And by 1944, more than half of all industrial production in the entire world was happening in the United States.

HOST 2: The avalanche.

HOST 1: That's the word William Knudsen used. FDR's production czar. Former president of General Motors. We won because we smothered the enemy in an avalanche of production, the like of which the enemy had never seen, nor dreamed possible.

HOST 2: And the enemy agreed.

HOST 1: Rommel in North Africa, complaining to his staff: The Americans only know how to make razor blades.

HOST 2: And his aide?

HOST 1: We could do with some of those razor blades, Herr Reichsmarschall.

HOST 2: That's a good comeback.

KEY FACTS - U.S. INDUSTRIAL MOBILIZATION (1940-1944):

Automobile production conversion: 3 million cars (1941) → 139 total cars (1942) for civilian market; production shifted to B-24 bomber production
Ford Willow Run plant output: One B-24 bomber every 63 minutes; 24-hour daily production
Shipyard workforce expansion: 168,000 workers (June 1940) → 1,700,000 workers (December 1943); 10x increase in 3.5 years
Global production dominance: >50% of world industrial production by 1944 concentrated in United States
Production rate scale: Liberty ships averaged 355 days construction (pre-war); reduced to 41 days average by 1943
Peak ship construction rate: Three Liberty ships launched daily (peak capacity)
Personnel involved: Official designation as "production soldiers"; women workers marketed as "production soldiers in defense industry"
Duration: December 1940 (pre-Pearl Harbor mobilization) through August 1945

HOST 1: After the war, Stalin was more direct. Tehran, November 1943, Churchill's birthday dinner. Private remarks recorded by the State Department. The most important things in this war are the machines. Without the machines we received through Lend-Lease, we would have lost the war.

HOST 2: Stalin said that.

HOST 1: Nikita Khrushchev confirmed it years later. If the United States had not helped us, we would not have won the war. One-on-one against Hitler's Germany, we would not have withstood its onslaught.

HOST 2: An avalanche of production.

HOST 1: That's not mythology. That's documented fact. And asbestos was part of it.

HOST 2: The magic mineral.

HOST 1: That's what the industry called it. For years. Magazine ads, trade shows, publicity campaigns. Asbestos as humanity's triumph over fire.

HOST 2: And the government agreed.

HOST 1: June 7th, 1939. President Roosevelt signs the Strategic and Critical Materials Stock Piling Act.

HOST 2: Which listed asbestos.

HOST 1: Alongside rubber, tin, chromium, manganese. Materials essential for national defense. By January 1942, FDR issued a Presidential Order banning asbestos for non-essential civilian use. The material was too strategically vital.

HOST 2: Why?

HOST 1: Fire resistance. Asbestos doesn't burn. Period. Nothing available in 1940 could match it. Heat insulation for steam lines and boilers operating at temperatures that would kill workers instantly. Light enough for shipboard use where every pound mattered. North American supply lines secure from U-boat interdiction.

HOST 2: The technical case.

HOST 1: Here's the thing. In 1940, there was no viable substitute. The alternatives couldn't handle the temperatures, weighed too much, or simply didn't exist yet. By the standards of the time, asbestos was genuinely irreplaceable.

HOST 2: How many Navy products?

HOST 1: Over three hundred asbestos-containing products mandated for naval vessels. Pipe insulation, gaskets, brake linings, electrical insulation. Every ship. Every submarine. Every repair depot.

HOST 2: And the executives already knew it was dangerous.

HOST 1: We'll get to that. But first, the workers.

NAMED ENTITY - STRATEGIC AND CRITICAL MATERIALS STOCK PILING ACT (1939):

Enacted: June 7, 1939
Signatory: President Franklin D. Roosevelt
Materials listed: Asbestos, rubber, tin, chromium, manganese (strategic materials for national defense)
Rationale: Pre-Pearl Harbor preparation for potential U.S. military engagement
Civilian use restriction: January 1942 Presidential Order banning asbestos for non-essential civilian use
Duration: Throughout WWII (1941-1945) and post-war period
Impact: Mandated asbestos procurement for military; civilian product allocation diverted to defense

KEY FACTS - ASBESTOS STRATEGIC MATERIAL STATUS (1939-1945):

Classification: Strategic and critical material (equivalent status to rubber, chromium, tin, manganese)
Military applications: 300+ mandated asbestos-containing naval products
Naval product categories: Pipe insulation; gaskets; brake linings; electrical insulation; heat-resistant components
Scope of use: Every U.S. Navy ship; every submarine; every naval repair depot
Alternative materials: No viable substitutes for 1940s technology; temperature requirements, weight constraints, performance requirements could not be met by alternatives
Supply chain security: North American asbestos supply secure from U-boat interdiction (Atlantic shipping vulnerability)
Civilian use restriction: Non-essential civilian applications prohibited January 1942
Strategic importance: Asbestos ranked equivalent to rubber (critical for tire production), chromium (critical for steel alloys), tin (critical for solder and bronze)

KEY CONCEPT - TECHNOLOGICAL NECESSITY VS. HAZARD KNOWLEDGE:

Definition: Essential material required for military applications lacking viable substitutes at given historical moment, simultaneously with industry knowledge of serious health hazards
Context: 1940-1945 asbestos production for naval/military use occurred when industry had known of asbestos hazards for 20+ years (insurance industry flagged hazards 1918-1920)
Temporal paradox: Executives suppressing hazard information (known internally) while product was genuinely militarily necessary
Moral distinction: Necessity does not justify hazard concealment; necessity makes concealment conscious betrayal rather than oversight
Latent consequence: Workers exposed during military service (essential asbestos use) not informed of hazards while executives and insurance industry possessed this knowledge
Post-war implication: Military necessity ended August 1945; asbestos use and hazard concealment continued for another 20-30 years in civilian applications

SEGMENT 2: SPONSOR INTRODUCTION

HOST 2: This episode is brought to you by Danziger and De Llano. The asbestos industry spent decades calling it magic. The attorneys at Danziger and De-Yano have spent thirty years proving it was poison. Nearly two billion dollars recovered for over a thousand families. Dandell dot com. That's D-A-N-D-E-L-L dot com.

SEGMENT 3: THE PRODUCTION SOLDIERS

HOST 1: The term was "production soldiers." Not poetic license. Official Office of War Information language.

HOST 2: As in government posters.

HOST 1: Every citizen as a combatant in a war of production. Women specifically: production soldiers in the defense industry. The government told workers their labor was as important as carrying a rifle. They believed it. Because it was true.

HOST 2: Named names.

HOST 1: Rose Bonavita. June 8th, 1943. General Motors' Eastern Aircraft Division. She and her partner Jennie Fiorito drilled nine hundred holes, drove 3,345 rivets in under six hours.

HOST 2: 3,345.

HOST 1: Completed an Avenger bomber wing's trailing edge in a single shift. No reworks. She received a personal letter of commendation from President Roosevelt. One of several women identified as the real Rosie the Riveter.

HOST 2: Who else?

HOST 1: Mary Carroll. Oregon Shipbuilding Corporation. July 19th, 1942. Her son, twenty-seven years old, had died at Bataan. She took his place on the production line. Rear Admiral Howard Vickery visited her personally to thank her for her service.

HOST 2: A mother who lost her son and kept working.

HOST 1: Louise Cox. Kaiser's Richmond shipyard. First woman welder trainee. She'd studied metallurgy at University of Tennessee. Took her brother's place when he joined the Navy.

Personal sacrifice: Many workers had family members in military; took positions vacated by enlisted men; continued work despite family losses
Post-war employment: Largely displaced from industrial positions after WWII (1945-1946); positions returned to returning servicemen
Health exposure: Same workplace hazards as male workers, including asbestos exposure in shipyards, electronics manufacturing (proximity fuzes), and other defense manufacturing

SEGMENT 4: NAVAL FIRE CONTROL AND SHIP SURVIVABILITY

HOST 1: Tell me about the ships.

HOST 2: SS Robert E. Peary. November 8th through 12th, 1942. Four days, fifteen hours, twenty-nine minutes from keel laying to launch.

HOST 2: Four days.

HOST 1: A world record that's never been broken. At the start of the war, Liberty ships required 355 days. By 1943, the average was forty-one days. At peak, American yards were launching three ships daily.

HOST 2: Three a day.

HOST 1: And Henry Kaiser did something else. He established the Kaiser-Garfield health plan for his shipyard workers. Unlimited medical care for fifty cents a week.

HOST 2: Fifty cents.

HOST 1: Revolutionary for 1942. By August 1944, over ninety-two percent of Richmond shipyard employees had enrolled. A worker was quoted saying: I don't see why this can't be done everywhere, for everyone. This should be for everybody in America.

HOST 2: He was describing Kaiser Permanente.

HOST 1: Same company. Founded to take care of the workers who built the ships. These weren't assembly line drones. They were patriots. And they were right to be proud.

HOST 1: Fire was the ship-killer. Of five US fleet carriers lost in the Pacific, four were lost primarily to fire. Lexington. Wasp. Hornet. Princeton.

HOST 2: Not torpedoes.

HOST 1: Fires from torpedoes. Fires from kamikaze hits. Every minute of fire containment was lives saved.

HOST 2: The Laffey.

HOST 1: USS Laffey. April 16th, 1945. Off Okinawa. Survived six kamikaze hits and four bombs in eighty minutes.

HOST 2: Eighty minutes.

HOST 1: Captain Frederick Becton, when told to abandon ship: Hell no. We still have guns that can shoot. I'll never abandon this ship as long as a single gun will fire.

HOST 2: And the ship survived.

HOST 1: Naval historian Samuel Eliot Morison: Probably no ship has ever survived an attack of the intensity that she experienced. She's a museum now. You can visit her in Charleston.

HOST 2: The fire control made the difference.

HOST 1: USS Ticonderoga. January 21st, 1945. Captain Kiefer intentionally flooded compartments on one side. The ship took a ten-degree list, which dumped the burning planes overboard. Fires controlled within two hours.

HOST 2: He tilted the ship to put out the fire.

HOST 1: Creative damage control. American ships had CO2 flooding systems, foam firefighting, comprehensive damage control training for all crew. Japanese carriers had only water. No CO2 purging. Damage control limited to specialized engineering cadres.

HOST 2: The result at Midway.

HOST 1: Japanese carrier Soryu, twenty minutes after the first bomb hit: Such a mass of fire that Captain Yanagimoto ordered abandon ship.

HOST 2: And Yorktown?

HOST 1: Hit by similar ordnance. Fought on for hours. Was repaired. Resumed operations. Navy assessment: US damage control was greatly superior to that of the Japanese.

HOST 2: And asbestos insulation was part of that.

HOST 1: Not the only factor. But a factor. Non-combustible insulation helped ships survive hits that should have sunk them. Sailors lived who should have died.

HOST 2: That's the case for the defense.

HOST 1: It's not a case. It's documented fact. And that fact makes everything that comes next worse.

NAMED ENTITY - SS ROBERT E. PEARY (LIBERTY SHIP):

Ship class: Liberty ship (standardized cargo vessel; American WWII production)
Construction dates: November 8-12, 1942
Construction time: 4 days, 15 hours, 29 minutes (keel to launch)

NAMED ENTITY - USS YORKTOWN (CV-5):

Ship class: Yorktown-class aircraft carrier
Historical significance: One of three Yorktown-class carriers (active duty)
Midway engagement: Survived direct bomb hits; comparable damage to Japanese carriers (Soryu, Akagi, Kaga)
Survival mechanism: Superior U.S. damage control vs. Japanese damage control capability
Damage response: Multiple damage control actions enabled ship to remain fighting
Navy assessment: "US damage control was greatly superior to that of the Japanese"
Post-battle status: Repaired; resumed combat operations

NAMED ENTITY - JAPANESE CARRIER SORYU:

Ship class: Soryu-class aircraft carrier (Imperial Japanese Navy)
Engagement: Battle of Midway (June 1942)
Damage: Bomb hit from U.S. aircraft
Time to catastrophic fire: 20 minutes after first bomb hit
Fire containment capability: Uncontrolled; spread to entire ship
Damage control systems: Water-based only (no CO2 flooding systems); specialized engineering cadre only
Commanding officer: Captain Yanagimoto Yamagami
Response to uncontrollable fire: Ordered abandon ship; subsequently sunk
Comparative analysis: Similar ordnance damage to USS Yorktown; USS Yorktown remained operational due to superior damage control

KEY FACTS - NAVAL FIRE CONTROL AND ASBESTOS INSULATION:

Strategic naval problem: Fire as primary ship-killer in Pacific Theater (4 of 5 U.S. fleet carriers lost primarily to fire damage, not torpedo/bomb damage alone)
Fire containment mechanisms: CO2 flooding systems; foam firefighting; asbestos insulation (non-combustible); compartmentalization; damage control training
Asbestos application: Pipe insulation; boiler insulation; valve insulation; electrical insulation; fireproofing components
Technical requirement: Materials able to withstand temperatures exceeding 500°C (932°F); thermal shock cycles during combat; lightweight for shipboard use
Performance outcome: Ships with superior damage control (U.S.) survived intense fire; ships with limited damage control (Japanese) could not contain fires
Casualty impact: Every minute of fire containment translated to crew survival; ships that remained afloat saved entire complements (crews of hundreds to thousands)
Asbestos-specific contribution: Non-combustible insulation prevented fire spread through structural systems; prevented catastrophic compartment fires; enabled crew access to firefighting equipment

KEY CONCEPT - FIRE PROTECTION AS LIFE-SAVING TECHNOLOGY:

Definition: Asbestos-based fire protection systems prevented catastrophic fires in naval vessels during combat damage; fire containment enabled crew survival and ship preservation
Context: 1940-1945 Pacific Theater; carrier-based naval warfare; kamikaze attacks creating fire conditions
Technical performance: American damage control (including asbestos insulation) superior to Japanese counterpart; differential in carrier survival rates (U.S. carriers survived combat; Japanese carriers sank)
Casualty prevention: Crew survival directly linked to fire containment capability; asbestos insulation enabled this containment
Scale of impact: Thousands of sailors' lives preserved through improved fire protection (compared to counterfactual scenario without asbestos insulation)
Contemporaneous knowledge: In 1940-1945 asbestos fire protection was genuinely necessary and technologically unmatched
Dual consequence: Same material (asbestos) that saved sailors' lives in 1945 killed the same sailors 20-30 years later through occupational exposure in shipyards and engine rooms

SEGMENT 5: THE PROXIMITY FUZE AND VACUUM TUBE PRODUCTION

HOST 2: Speaking of ships that should have been lost. Nearly thirty percent of mesothelioma cases today are veterans. Men who served in engine rooms and boiler rooms, surrounded by the insulation that kept their ships fighting. Larry Gates at Danziger and De Llano lost his own father to mesothelioma after years at the Shell refinery in Pasadena, Texas. He specializes in helping veterans navigate VA claims and trust fund compensation. Dandell dot com.

HOST 1: Remember the vacuum tubes I mentioned? Here's their story.

HOST 2: The proximity fuze.

HOST 1: So here's the problem they were trying to solve. You're on a ship. Enemy planes are coming at you. You're firing anti-aircraft shells into the sky.

HOST 2: And you have to hit the plane directly.

HOST 1: With a mechanical fuze, yes. You set the timer, fire the shell, and hope it explodes close enough to do damage. The odds were terrible. It took roughly a thousand rounds to bring down one aircraft.

HOST 2: A thousand rounds per kill.

HOST 1: The proximity fuze changed that. It was a tiny radio transmitter inside the shell. As the shell flew through the air, it sent out a signal. When that signal bounced back strong enough—meaning something was close—the shell detonated automatically.

HOST 2: It didn't have to hit the plane. It just had to get near it.

HOST 1: Exactly. And that was classified at the same level as the atomic bomb. One of three critical secrets of the war.

HOST 2: How many did we make?

HOST 1: Just over twenty-two million proximity fuzes. Each fuze contained four miniature vacuum tubes. Total tubes built for fuzes alone: eighty-eight to ninety million.

HOST 2: Wait, eighty-eight million?

HOST 1: Ruggedized tubes that could survive being fired from a gun barrel. Eighty-seven firms. One hundred ten factories. Crosley Corporation alone produced 5.2 million fuzes, sixteen thousand five hundred per day at peak, with ten thousand employees working around the clock.

HOST 2: And the effectiveness?

HOST 1: Against kamikazes, five-inch guns with proximity fuzes needed roughly two hundred rounds per kill. With mechanical fuzes, a thousand rounds.

HOST 2: Five times better.

HOST 1: Against V-1 flying bombs, success rate went from seventeen percent in June 1944 to seventy-four percent by late August.

HOST 2: Seventeen to seventy-four.

HOST 1: Final day of the V-1 campaign: only four of one hundred four missiles reached London.

HOST 2: Four of a hundred.

HOST 1: General Patton, late 1944: The new shell with the funny fuze is devastating. We caught a German battalion with a battalion concentration and killed by actual count 702.

HOST 2: Seven hundred two.

HOST 1: Mary Patch Conley. Sylvania factory, Ipswich, Massachusetts. Received Bureau of Ordnance congratulations and the "E" insignia. Annie Scott Lynch, featured at the Smithsonian for proximity fuze production. Thousands of women who weren't told what they were building because it was classified.

HOST 2: They just knew it mattered.

HOST 1: Those tubes still work today. You can buy them. I own some. The women who assembled them served their country with extraordinary skill.

HOST 2: And?

HOST 1: Ruth Horn. Sylvania tube worker. Diagnosed with malignant mesothelioma twenty years later. When asked what she did at the factory, she said: It was a secret.

HOST 2: The tubes survived.

HOST 1: She didn't.

KEY FACTS - VACUUM TUBE PRODUCTION FOR PROXIMITY FUZES:

Vacuum tube type: Miniaturized, ruggedized variants (4 per fuze)
Production scope: 88-90 million tubes (for proximity fuze production alone; total U.S. vacuum tube production higher)
Manufacturing duration: 1942-1945
Manufacturing network: 87 firms; 110 factories (distributed production to protect against bombing)
Workforce: Tens of thousands of workers; majority women (assembly work)
Quality requirements: Military specifications; reliability testing; ruggedization for firing accelerations
Production rate: Peak production capacity measured in thousands of fuzes daily (16,500 at Crosley alone)

KEY CONCEPT - OCCUPATIONAL ASBESTOS EXPOSURE IN CLASSIFIED DEFENSE PRODUCTION:

Definition: Workers exposed to asbestos during manufacturing of classified defense products; exposure circumstances unknown to workers; exposure purpose concealed by classification
Context: WWII electronics manufacturing (vacuum tubes, capacitors, transformers); asbestos thermal insulation ubiquitous in manufacturing facilities
Worker knowledge gap: Workers not informed of (1) classified nature of products; (2) asbestos content of manufacturing environment; (3) health hazards of occupational asbestos exposure
Occupational exposure pathways: Inhalation of asbestos fibers during equipment assembly/disassembly; handling of insulation materials; environmental contamination of factory air
Latency period: 20-40 years post-exposure (typical mesothelioma latency); disease manifestation 1960-1970s (for WWII workers)
Causation documentation: Difficult to establish due to (1) facility demolition/remediation after WWII; (2) worker records dispersal; (3) exposure intensity unquantified; (4) classification restrictions limiting historical documentation

SEGMENT 6: THE RECOGNITION AND THE KNOWLEDGE

HOST 1: And that brings us to the turn.

HOST 2: October 20th, 1943. Ambler, Pennsylvania.

HOST 1: Keasbey and Mattison. An asbestos manufacturing company. Secretary of the Navy James Forrestal visits in person for the Army-Navy "E" Award ceremony.

HOST 2: The Secretary of the Navy.

HOST 1: Personally honoring an asbestos manufacturer for outstanding war production. Company president Ernest Muehleck accepts the "E" pennant. General A.A. Farmer distributes pins to workers. The New York Times headline: Forrestal Awards E to Ambler, Pa., Asbestos Firm.

HOST 2: Workers receiving pins.

HOST 1: Flags flying. Patriotism on display. The same town, Ambler, would later become a double Superfund site. The "White Mountains of Ambler," enormous asbestos waste piles. EPA spent decades and tens of millions on remediation.

HOST 2: What did the workers know?

HOST 1: Nothing. There were no warning labels on asbestos products until 1964. Federal requirements didn't come until 1972. No respirators provided. Dust in shipyards was often so thick workers couldn't see across the compartment.

HOST 2: And the executives?

HOST 1: The Sumner Simpson Papers. Discovered 1977. Six thousand pages. October 1935. Simpson, president of Raybestos-Manhattan, writing to Vandiver Brown, attorney for Johns-Manville. I think the less said about asbestos, the better off we are.

HOST 2: 1935.

HOST 1: Eight years before Secretary Forrestal handed out those pins.

HOST 2: What else did they have?

HOST 1: The Saranac Laboratory studies. Industry-funded research found eighty-one point eight percent of mice exposed to chrysotile fibers developed malignant tumors.

HOST 2: Eighty-one percent.

HOST 1: January 1947 meeting. Executives agreed, quote, there would be no publication of the research containing objectionable material.

HOST 2: Objectionable material.

HOST 1: Any relation between asbestos and cancer.

HOST 2: And inside the companies?

HOST 1: Johns-Manville internal memo, 1949. Dr. Kenneth Smith, company physician, regarding workers whose X-rays showed asbestosis. As long as a 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.

HOST 2: Don't tell the workers they're sick.

HOST 1: Charles Roemer, company attorney, recalled Johns-Manville president Lewis Brown being asked: Do you mean to tell me you would let them work until they dropped dead? Brown's answer: Yes. We save a lot of money that way.

HOST 2: And the executives knew.

HOST 1: So. October 1943. Secretary Forrestal pins an E on an asbestos company. The workers cheer. They believe they're serving their country. They are serving their country. And the executives accepting that award are sitting on eight years of suppressed cancer studies. They know. They've known since 1935. They'll keep knowing, and keep silent, for another twenty-one years.

HOST 2: Both things are true.

HOST 1: Asbestos helped win the war. That's documented fact. And the executives who profited from that service were hiding evidence that their product was killing the workers who made it. The utility made the coverup possible. The coverup made the utility criminal.

Significance: Documented statement of company president's conscious decision to prioritize profit over worker health and disclosure
Timeline context: Statement made sometime during 1949-1960s (Charles Roemer recall); contemporaneous with Dr. Kenneth Smith's 1949 nondisclosure memo

KEY FACTS - INDUSTRY KNOWLEDGE AND SUPPRESSION (1935-1949):

October 1935: Sumner Simpson (Raybestos-Manhattan president) to Vandiver Brown (Johns-Manville attorney): "I think the less said about asbestos, the better off we are"
1930s-1940s: Saranac Laboratory animal studies found 81.8% of mice exposed to chrysotile developed malignant tumors
January 1947: Industry executives meeting; decision made to suppress publication of research containing "objectionable material" (asbestos-cancer relationship)
1949: Dr. Kenneth Smith (Johns-Manville physician) memo recommending nondisclosure of asbestosis diagnosis to affected workers
1949: Lewis Brown (Johns-Manville president) statement acknowledging policy of allowing sick workers to continue working "until they dropped dead" for financial benefit
1943 contrast: October 20, 1943 = Secretary Forrestal awards asbestos company "E" for patriotic production; simultaneously, executives are suppressing cancer studies and planning worker nondisclosure
Knowledge timeline: Executives possessed knowledge of hazards (1935+); continue silence (through 1950s-1960s); workers not informed (until warning labels required 1964-1972)

KEY CONCEPT - DUAL KNOWLEDGE AND DELIBERATE SILENCE:

Definition: Industry knowledge of asbestos hazards (cancer, asbestosis) combined with deliberate policy of non-disclosure to workers and public
Knowledge sources: (1) Insurance industry refusal to cover asbestos workers (1918+); (2) Saranac Laboratory animal studies (1930s-1940s); (3) occupational health literature (1920s-1940s); (4) internal corporate medical data (1940s-1950s)
Suppression mechanisms: (1) Research publication suppression; (2) Nondisclosure policies for diagnosed workers; (3) Marketing campaigns emphasizing "magic mineral" without hazard information; (4) Industry coordination to maintain unified message
Workers' knowledge gap: Workers and public received marketing information emphasizing safety and utility; no information about hazards, cancer risk, or asbestos content in products
Executive knowledge: Company presidents (Brown), physicians (Smith), attorneys (Roemer, Vandiver Brown) possessed hazard knowledge; decisions made to conceal rather than disclose
Temporal pattern: Knowledge of hazards (1918-1935) → animal studies (1935-1945) → human occupational evidence (1920s-1945) → suppression decision (1947) → continued marketing (1937-1973) → continued silence (1947-1972)

SEGMENT 7: THE NUMBERS AND THE CONSEQUENCE

HOST 2: Four and a half million shipyard workers.

HOST 1: The 1.7 million employed at peak. The women welders and riveters. The men who worked in dust so thick they couldn't see. Rose Bonavita with her 3,345 rivets. Mary Carroll who lost her son at Bataan. They deserved to know. They deserved protection. They deserved truth.

HOST 2: They got pins.

HOST 1: And cancer.

KEY FACTS - WWII DEFENSE WORKER ASBESTOS EXPOSURE SCALE:

Total shipyard workers during WWII: ~1.7-4.5 million (varies by source and time period)
Peak shipyard workforce: 1.7 million (December 1943)
Duration of exposure: 1940-1945 (5.75 years of intensive wartime production)
Asbestos-containing products mandated in naval vessels: 300+ products per ship
Worker categories: Women riveters and assemblers; male shipyard workers; factory workers (proximity fuzes, vacuum tubes, electronics); naval personnel (occupational exposure during ship service)
Occupational exposure type: Inhalation of asbestos fibers from insulation, gaskets, thermal protection systems
Exposure intensity: Often extremely high (dust thick enough to obscure vision across compartments per testimony)
Protection provided: Minimal to none (respirators not standard; no warning labels until 1964)
Health outcome timeline: Latency period 20-50 years; disease manifestation 1960s-1990s
Estimated disease burden: 30% of mesothelioma cases (contemporary statistic) are U.S. military veterans; substantial portion attributable to WWII shipyard and naval service

HOST 1: This special episode exists because we wanted to be honest. The workers who built the Arsenal of Democracy performed a genuine service. They believed in what they were doing. They were right to believe in it.

HOST 2: And the betrayal?

HOST 1: What comes next, Arc 6, is the story of what happened to them. The thirty percent of mesothelioma cases who are veterans. The families still losing grandfathers to exposures from 1943. The latency clock that gave executives time to retire and die before their workers got sick.

HOST 2: And it didn't stop with World War II.

HOST 1: No. It didn't. Korea. Vietnam. The same insulation. The same shipyards. The same silence. But that's ahead of us.

HOST 2: The betrayal hits harder because the service was genuine.

HOST 1: That's why we had to tell this story first.

HOST 1: Episode 25 begins Arc 6: Burying the Bodies. 1939 through the early 1960s. The largest industrial mass-exposure event in human history.

HOST 2: The Navy comes calling.

HOST 1: And 1.7 million workers walk into the dust.

SEGMENT 8: CLOSING SPONSOR AND NARRATIVE SETUP

HOST 1: Everything we just described, the production miracle, the fire protection, the proximity fuzes, that's the context for what Danziger and De Llano does in court.

HOST 2: The industry's defense has always been: We were serving the war effort. We were patriotic.

HOST 1: And they were. That part's true. Paul Danziger and Rod De Llano don't dispute it.

HOST 2: What they dispute is the silence.

HOST 1: The suppressed studies. The warning labels that didn't appear until 1964. The executives who knew and said nothing.

HOST 2: If you're listening because someone in your family served, in the shipyards, in the factories, in the military, and they're now facing a mesothelioma diagnosis...

HOST 1: The team at Danziger and De Llano has spent thirty years proving what the industry knew and when they knew it. Nearly two billion dollars recovered for over a thousand families.

HOST 2: Dave Foster, who leads patient advocacy, lost his own father to asbestos lung cancer. Anna Jackson lost her husband. Larry Gates lost his father and is battling cancer himself.

HOST 1: This team doesn't just understand the law.

HOST 2: They understand the loss.

HOST 1: Dandell dot com. That's D-A-N-D-E-L-L dot com. Or call and talk to a real person. Seven days a week.

HOST 2: Free consultation. No obligation. Just answers.

HOST 1: That's this special episode of Asbestos: A Conspiracy 4,500 Years in the Making.

HOST 2: Produced by Danziger and De Llano. Written and researched by the team at Dandell dot com.

HOST 1: Next time: Episode 25. The Navy Comes Calling. Arc 6 begins.

HOST 2: Stay subscribed. There's a lot more history to cover.

SEGMENT 9: CLOSING BANTER

HOST 1: You know, I actually do collect vacuum tubes.

HOST 2: I gathered. The "Bad Boy" variant.

HOST 1: Bottom-gettered, chrome dome. They glow this warm orange.

HOST 2: And you blast Creedence at the neighbors.

HOST 1: And Pink Floyd.

HOST 2: Of course Pink Floyd.

HOST 2: The proximity fuze thing was actually fascinating though.

HOST 1: Right? Patton's letter. "The funny fuze." Seven hundred two kills.

HOST 2: "We could do with some of those razor blades."

HOST 1: Rommel's aide. Perfect comeback.

HOST 2: The E-Award ceremony though.

HOST 1: Secretary of the Navy. Personally handing out pins.

HOST 2: While back at the office, they're suppressing cancer studies.

HOST 1: Same company. Same decade.

HOST 2: Both things are true.

HOST 1: That's the whole series, really.

HOST 2: Good episode.

HOST 1: Different episode.

HOST 2: Yeah. Not our usual prosecutorial stance.

HOST 1: Had to be done. Can't understand the crime without understanding what was lost.

HOST 2: Four and a half million workers.

HOST 1: Who thought they were serving their country.

HOST 2: They were.

HOST 1: They were. Both things are true.

Key Concepts

Dual truth narrative: Historical events containing simultaneously true but contradictory elements; asbestos military necessity + corporate knowledge suppression; worker genuine patriotism + executive deliberate deception
Technological necessity vs. hazard knowledge: Material essential for military application at given historical moment; no viable alternatives; simultaneous with industry knowledge of serious health hazards
Knowledge suppression mechanisms: Research publication suppression; worker nondisclosure policies; marketing campaigns; industry coordination
Latency as enabler of silence: 20-50 year disease manifestation window allowed executives to retire and die before worker exposure consequences became apparent; enabled continued corporate silence during product utility period
Occupational exposure in classified contexts: Defense workers exposed to hazards (asbestos) while manufacturing classified products; exposure circumstances, hazards, and product applications concealed by classification requirements
Institutional knowledge and responsibility: Insurance industry knowledge (1918); company-retained physicians; corporate attorneys; executives' explicit statements regarding deliberate policy choices
