In the annals of American corporate malfeasance, few cases rival the calculated destruction wrought by three businessmen who chose private profit over public welfare. Thomas Midgley Jr., Charles Kettering, and Frank Howard orchestrated one of history's most devastating environmental crimes, poisoning entire generations with leaded gasoline while systematically deceiving the public about its dangers. Their decisions would cost millions of lives, reduce global intelligence, increase crime rates, and contaminate the entire planet with a toxin they knew to be deadly (Muller, 2022).

The Culprits and Their Crimes

Thomas Midgley Jr.: The Architect of Mass Poisoning

Thomas Midgley Jr., a mechanical and chemical engineer at General Motors, stands as history's most destructive inventor. Despite knowing lead's ancient reputation as a deadly poison, Midgley deliberately chose to add tetraethyl lead to gasoline in 1921. His decision was not born of ignorance but of calculated greed. When ethanol proved effective as an anti-knock agent, Midgley rejected it because it offered little profit potential. Lead, however, was cheap, required only tiny amounts, and could be patented for enormous gain.

Midgley's moral bankruptcy reached its nadir in his systematic campaign of deception. After workers began dying from lead poisoning at production facilities, he staged fraudulent press conferences, pouring tetraethyl lead on his hands and inhaling its vapors for a full minute while claiming he could "do this daily without harm." Yet Midgley himself was secretly recovering from lead poisoning and avoided his own product whenever possible. He knew exactly what he was unleashing on the world (Kitman, 2022).

Charles Kettering: The Corporate Enabler

Charles Kettering, Midgley's boss and later president of the Ethyl Corporation, bears equal responsibility for this catastrophe. As the man who hired Midgley and directed the anti-knock research, Kettering had both the authority and responsibility to choose safer alternatives. Instead, he became lead's most powerful champion, co-patenting the process and establishing the corporate structure that would spread this poison globally.

Kettering's complicity deepened when worker deaths mounted. Rather than halt production, he partnered with DuPont and Standard Oil to form the Ethyl Corporation, creating a powerful corporate alliance dedicated to marketing mass destruction. His decision to continue operations despite mounting casualties reveals a man who valued profits over human lives (Kovarik, 2005).

Frank Howard: The Defender of Poison

Frank Howard, president of Standard Oil, perhaps displayed the most callous disregard for human welfare. When public health concerns grew, Howard dismissed them with chilling arrogance, declaring that his industry would not "give up what has come to the industry like a gift from heaven, on the possibility that a hazard may be involved in it." This statement, made while people were already dying from lead exposure, reveals a man who viewed human life as expendable in pursuit of corporate profits.

Howard's role extended beyond mere defense of the product. He actively participated in the cover-up, funding scientists who falsely claimed lead was "natural" and therefore harmless, while suppressing research that revealed the truth about lead's devastating effects (Alan & Hogan, 2003).

How Greed Trumped Safety

The path to this disaster began with a legitimate engineering problem. After the founder of the CarterCar Company died from a hand-crank accident in 1908, the automotive industry developed self-starting engines which required higher compression ratios. The technology proved convenient for drivers, but unfortunately these high-compression engines suffered from "knocking," premature combustion of the fuel-air mixture in the cylinder that reduced engine power and damaged components.

When Kettering tasked Midgley with solving this problem in 1916, the young engineer encountered a clear choice between public welfare and private profit. His experiments revealed that ethanol worked effectively as an anti-knock agent, requiring about 10% of the fuel mixture. However, ethanol could not be patented, offered limited profit margins, and was already widely available through existing distilling operations (Kovarik, 2003).

Lead presented a far better opportunity for those seeking riches. Tetraethyl lead worked in tiny concentrations (one part per thousand), was cheap to produce, and could be patented and controlled. Most crucially, it promised enormous profits—Midgley predicted they would make "$200 million, maybe even more," equivalent to over $3 billion today.

Kettering and Midgley knew they were choosing the dangerous path. Lead had been recognized as a deadly poison for thousands of years. Benjamin Franklin had warned in 1786 that lead had been used "far too long considering its known toxicity." Doctors and public health officials from MIT, Harvard, Yale, and the US Health Service explicitly warned against using lead in gasoline, calling it "a creeping and malicious poison" and "a serious menace to public health" (Rosner & Markowitz, 1985).

Yet the promise of unprecedented profits proved irresistible. Kettering and Midgley first partnered with General Motors in 1923 to establish commercial production of tetraethyl lead. This subsidiary soon collaborated with Standard Oil of New Jersey and evolved the Ethyl Gasoline Corporation where they and Frank Howard all served as the chief executives.

Willful Ignorance and Deliberate Harm

These executives knew they were causing harm from the very beginning. Midgley personally experienced lead poisoning in 1923, forcing him to take extended leave for his health. Workers were dying in their factories by 1924. Public health officials were issuing explicit warnings about the dangers.

Yet rather than halt production, they focused upon deception:

Deliberate Mislabeling: They named their product "Ethyl" to disguise its lead content, hoping consumers would confuse it with ethyl alcohol (ethanol), a relatively harmless substance.

Fraudulent Safety Claims: Despite knowing lead's toxicity, they launched marketing campaigns claiming their product was safe and emphasized how it improved engine performance and fuel economy.

Cover-up of Worker Deaths: When factory workers began dying from lead poisoning—five deaths within two months at the New Jersey plant alone—the executives continued production and blamed the deaths on worker carelessness rather than product toxicity.

Personal Hypocrisy: Most damning, Midgley promoted his product as safe for daily public use while he himself was secretly recovering from lead poisoning caused by exposure to his invention. After recovering, he steadily reduced his contact with concentrated TEL as worker poisonings mounted at his company's production plants  (Kovarik, 2015; Markowitz & Rosner, 2013; Rosner, 2004).

The gap between their private knowledge and public statements reveals not ignorance but calculated malice. They chose to poison the public while knowing exactly what they were doing.

Suppression of Dissent and Corporate Influence

The Ethyl Gasoline Corporation (EGC) and its parent companies exerted extensive influence over scientific and regulatory processes around tetraethyl lead (TEL), including funding aligned experts, securing control over government studies' publication, and mounting legal and public-relations campaigns. Though their influence over politicians and regulatory bodies was indirect, it was pursued deliberately through research funding, publication controls, and institutional alignments (Kovarik, 2003).

A widely cited historical review notes that industry developed "hegemony over scientific evidence" via "professional ties in the medical establishment and the persuasive influence of lucrative grants," establishing a network that "successfully excluded from the scientific literature and professional reports any negative opinion" on public lead hazards, implicating organizations like the AMA, APHA, and U.S. Public Health Service in a web of obligations limiting independent analysis (Kovarik, 2005).

Other studies document that EGC negotiated the right to review and approve results of the 1925 U.S. Public Health Service investigation before release, ensuring "public anxiety would not be aroused," an explicit example of industry control over governmental science dissemination (Nriagu, 1990).

Study of the 1920s Ethyl controversy details how the industry succeeded at the 1925 Surgeon General's hearing in sidelining testimony on safer alternatives (like ethanol) and benefited from a burden-of-proof posture that favored continued TEL sales despite worker poisonings, reflecting coordinated corporate strategy rather than neutral scientific arbitration (Kovarik, 2003).

Secondary accounts describe a broader pattern of influence: the shaping of medical authority through figures such as Dr. Robert Kehoe, who was Ethyl's medical director and led the Kettering Laboratory at the University of Cincinnati. His influential position is credited with helping rescind bans and normalize TEL, illustrating how corporate-funded expertise influenced policy for decades (Nriagu, 1990).

Investigative syntheses recount that EGC and allies leveraged powerful connections in industry associations and government, marginalized critical scientists (e.g., after Clair Patterson challenged ambient lead), and used litigation to delay regulatory action—tactics consistent with purchasing or mobilizing influence even if it did not involve direct payments to specific politicians (Kovarik, 2011).

Journalism and retrospective analyses similarly emphasize the role of corporate wealth and control—GM, Standard Oil (New Jersey), and DuPont—over communications, legal strategy, and scientific framing during both the 1920s introduction and later regulatory challenges, reinforcing a pattern of influence rather than transparent, independent evaluation (Kitman, 2000).

Overall, there is clear documentation that EGC's contractual control over federal study publication, extensive funding of aligned medical expertise, strategic use of hearings and public demonstrations, and legal maneuvers to shape policy and delay restrictions.

Consequences: A Global Catastrophe

The human cost of these business decisions staggers the imagination. By the time leaded gasoline was finally banned globally (Algeria was last in 2021), the damage was irreversible:

Environmental Contamination: Present in the exhaust of innumerable engines, lead spread globally during the 20th century, contaminating air, water, soil, and even Antarctic snow. The poison reached literally every corner of the planet.

Mass Poisoning: More than half the current US population—170 million people—were exposed to dangerous lead levels in childhood. Those born between 1951 and 1980 suffered disproportionate harm.

Intellectual Devastation: Lead caused the loss of more than 800 million IQ points globally. The world became measurably less intelligent because of these businessmen's decisions.

Criminal Behavior: The correlation between childhood lead exposure and later criminal behavior is well-established. The rise in crime from the 1970s to 1990s mirrors childhood lead exposure patterns offset by 20 years, suggesting these executives contributed to decades of increased violence and social disorder (Reyes, 2007).

Mass Death: The United Nations has repeatedly estimated that eliminating leaded gasoline prevents on the order of more than 1.2 million premature deaths per year worldwide. Conservative estimates suggest that before it was banned, TEL lead killed 25 million Americans and potentially 100 million people worldwide (United Nations Environment Programme, 2011, 2021).

What They Gained: Profit Over People

The financial rewards were enormous. The Ethyl Corporation generated billions in revenue over decades. Midgley received prestigious scientific awards, including the Nichols Award from the American Chemical Society. The three men achieved wealth, recognition, and corporate power.

Their decisions revealed their core values: profit mattered more than human life, corporate success justified any level of deception, and short-term gains trumped long-term consequences. They viewed public's wellbeing as expendable in pursuit of private enrichment.

The Road Not Taken

Safer alternatives existed at every step throughout this saga:

Ethanol: Midgley's own research proved ethanol worked effectively. While requiring higher concentrations, it was non-toxic, renewable, and already being produced commercially.

Engine Redesign: Lower-compression engines that didn't knock were entirely feasible and were already in widespread use.

Other Anti-knock Compounds: Various non-toxic additives could have been developed with proper research investment.

Market Acceptance: Consumers would likely have accepted slightly higher fuel costs or modest performance trade-offs to avoid poisoning their families.

The executives chose the most dangerous path not because others didn't exist, but because it offered the highest profits and tightest corporate control.

Why No One Stopped Them: System Failures

Multiple institutional failures enabled this catastrophe:

Weak Regulatory Structures: No EPA existed, environmental protection laws were non-existent, and government agencies lacked authority to ban dangerous products. The regulatory state was too weak to challenge powerful corporations.

Corporate Capture: The executives used their vast wealth to "buy enough doctors, scientists, and politicians to remove all restrictions." They funded sympathetic researchers, lobbied government officials, and created an ecosystem of financial dependence that silenced opposition.

Market Failures: The economic system provided no mechanism to account for environmental and health costs. The price of gasoline never reflected its true social cost, creating perverse incentives that rewarded the most harmful products.

Information Asymmetry: Corporations controlled research and data, enabling systematic misinformation campaigns. The public had no way to assess long-term risks, while industry insiders hoarded crucial safety information.

Political Powerlessness: Public health advocates lacked the political influence and financial resources to challenge corporate power. Academic warnings were dismissed while industry propaganda shaped public opinion.

Legal Inadequacies: Existing laws couldn't address the novel challenges of industrial-scale environmental poisoning. The legal system was unprepared for the scope and complexity of corporate malfeasance.

Conclusion: A Blueprint for Corporate Crime

The leaded gasoline catastrophe reveals how the desire for profit, personal advancement, and public status can drive American businesses to deliberately sacrifice public welfare for private gain when institutional safeguards fail. Thomas Midgley Jr., Charles Kettering, and Frank Howard didn't stumble into this disaster through poor judgment—they engineered it through calculated deception, systematic fraud, and callous disregard for human life.

Their success in poisoning the world for decades demonstrates the vulnerability of democratic societies to concentrated corporate power. When businesses control research, capture regulators, and manipulate public opinion, they can literally get away with mass murder while receiving awards and recognition.

The legacy of these three businessmen serves as a warning: without strong regulatory structures, transparent information systems, and mechanisms to hold corporations accountable, the pursuit of private profit will continue to devastate public welfare. Their crimes were not aberrations but the predictable result of a system that prioritizes corporate interests over human survival.

Today, as we face new environmental and health challenges, the story of leaded gasoline reminds us that businesses will poison the world if we let them. The only question is whether we will learn from this catastrophe or allow history to repeat itself with different toxins, different executives, and the same tragic results.
