On the frosty morning of Dec. 9, 1921, in Dayton, Ohio, researchers at a Normal Motors lab poured a brand new gasoline mix into one in all their check engines. Instantly, the engine started working extra quietly and placing out extra energy.
The brand new gasoline was tetraethyl lead. With huge earnings in sight – and only a few public well being rules on the time – Normal Motors Co. rushed gasoline diluted with tetraethyl result in market regardless of the identified well being dangers of lead. They named it “Ethyl” gasoline.
It has been 100 years since that pivotal day within the improvement of leaded gasoline. As a historian of media and the atmosphere, I see this anniversary as a time to mirror on the function of public well being advocates and environmental journalists in stopping profit-driven tragedy.

Lead and dying
By the early Twenties, the hazards of lead had been well-known – even Charles Dickens and Benjamin Franklin had written concerning the risks of lead poisoning.
When GM started promoting leaded gasoline, public well being consultants questioned its choice. One referred to as lead a critical menace to public well being, and one other referred to as concentrated tetraethyl lead a “malicious and creeping” poison.
Normal Motors and Normal Oil waved the warnings apart till catastrophe struck in October 1924. Two dozen staff at a refinery in Bayway, New Jersey, got here down with extreme lead poisoning from a poorly designed GM course of. At first they grew to become disoriented, then burst into insane fury and collapsed into hysterical laughter. Many needed to be wrestled into straitjackets. Six died, and the remaining had been hospitalized. Across the identical time, 11 extra staff died and several other dozen extra had been disabled at related GM and DuPont crops throughout the U.S.

Preventing the media
The auto and gasoline industries’ angle towards the media was hostile from the start. At Normal Oil’s first press convention concerning the 1924 Ethyl catastrophe, a spokesman claimed he had no thought what had occurred whereas advising the media that “Nothing must be mentioned about this matter within the public curiosity.”
Extra information emerged within the months after the occasion, and by the spring of 1925, in-depth newspaper protection began to seem, framing the difficulty as public well being versus industrial progress. A New York World article requested Yale College gasoline warfare professional Yandell Henderson and GM’s tetraethyl lead researcher Thomas Midgley whether or not leaded gasoline would poison individuals. Midgley joked about public well being considerations and falsely insisted that leaded gasoline was the one technique to elevate gasoline energy. To show the unfavorable impacts of leaded gasoline, Henderson estimated that 30 tons of lead would fall in a dusty rain on New York’s Fifth Avenue yearly.
Trade officers had been outraged over the protection. A GM public relations historical past from 1948 referred to as the New York World’s protection “a marketing campaign of publicity towards the general public sale of gasoline containing the corporate’s antiknock compound.” GM additionally claimed that the media labeled leaded gasoline “loony gasoline” when, actually, it was the employees themselves who named it as such.

Makes an attempt at regulation
In Might 1925, the U.S. Public Well being Service requested GM, Normal Oil and public well being scientists to attend an open listening to on leaded gasoline in Washington. The problem, in accordance with GM and Normal, concerned refinery security, not public well being. Frank Howard of Normal Oil argued that tetraethyl lead was diluted at over 1,000 to 1 in gasoline and subsequently posed no threat to the common individual.
Public well being scientists challenged the necessity for leaded gasoline. Alice Hamilton, a doctor at Harvard, mentioned, “There are millions of issues higher than result in put in gasoline.” And she or he was proper. There have been loads of well-known options on the time, and a few had been even patented by GM. However nobody within the press knew methods to discover that data, and the Public Well being Service, underneath stress from the auto and oil industries, canceled a second day of public hearings that might have mentioned safer gasoline components like ethanol, iron carbonyl and catalytic reforming.
By 1926, the Public Well being Service introduced that that they had “no good cause” to ban leaded gasoline, although inside memos complained that their analysis was “half baked.”
The rise and fall of leaded gasoline
Leaded gasoline went on to dominate gasoline markets worldwide. Researchers have estimated that a long time of burning leaded gasoline brought about tens of millions of untimely deaths, huge declines in IQ ranges and plenty of different related social issues.
Within the Nineteen Sixties and Seventies, the general public well being case towards leaded gasoline reemerged. A California Institute of Expertise geochemist, Clair Cameron Patterson, was discovering it troublesome to measure lead isotopes in his laboratory as a result of lead from gasoline was in all places and his samples had been continually being contaminated. Patterson created the primary “clear room” to hold on his isotope work, however he additionally revealed a 1965 paper, “Contaminated and Pure Lead Environments of Man,” and mentioned that “the common resident of the U.S. is being subjected to extreme persistent lead insult.”
In parallel, by the Seventies, the U.S. Environmental Safety Company determined that leaded gasoline needed to be phased out finally as a result of it clogged catalytic converters on vehicles and led to extra air air pollution. Leaded gasoline producers objected, however the objections had been overruled by an appeals court docket.
The general public well being considerations continued to construct within the Seventies and Nineteen Eighties when College of Pittsburgh pediatrician Herbert Needleman ran research linking excessive ranges of lead in kids with low IQ and different developmental issues. Each Patterson and Needleman confronted sturdy partisan assaults from the lead trade, which claimed that their analysis was fraudulent.
Each had been finally vindicated when, in 1996, the U.S. formally banned the sale of leaded gasoline for public well being causes. Europe was subsequent within the 2000s, adopted by growing nations after that. In August 2021, the final nation on the earth to promote leaded gasoline, Algeria, banned it.
A century of leaded gasoline has taken tens of millions of lives and to this present day leaves the soil in lots of cities from New Orleans to London poisonous.
The leaded gasoline story supplies a sensible instance of how trade’s profit-driven selections – when unsuccessfully challenged and controlled – may cause critical and long-term hurt. It takes particular person public well being leaders and robust media protection of well being and environmental points to counter these dangers.
