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

Lead and dying
By the early Nineteen Twenties, the hazards of lead had been well-known – even Charles Dickens and Benjamin Franklin had written in regards to the risks of lead poisoning.
When GM started promoting leaded gasoline, public well being consultants questioned its determination. One known as lead a critical menace to public well being, and one other known as concentrated tetraethyl lead a “malicious and creeping” poison.
Common Motors and Commonplace Oil waved the warnings apart till catastrophe struck in October 1924. Two dozen employees 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 similar time, 11 extra employees died and a number of other dozen extra had been disabled at comparable GM and DuPont vegetation throughout the U.S.
The information media started to criticize Commonplace Oil and lift issues over Ethyl fuel with articles and cartoons.

Combating the media
The auto and fuel industries’ perspective towards the media was hostile from the start. At Commonplace Oil’s first press convention in regards to the 1924 Ethyl catastrophe, a spokesman claimed he had no thought what had occurred whereas advising the media that “Nothing should 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 look, framing the difficulty as public well being versus industrial progress. A New York World article requested Yale College fuel warfare skilled Yandell Henderson and GM’s tetraethyl lead researcher Thomas Midgley whether or not leaded gasoline would poison individuals. Midgley joked about public well being issues and falsely insisted that leaded gasoline was the one strategy to elevate gasoline energy. To display the adverse 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 known as the New York World’s protection “a marketing campaign of publicity in opposition to the general public sale of gasoline containing the corporate’s antiknock compound.” GM additionally claimed that the media labeled leaded fuel “loony fuel” when, in actual fact, it was the employees themselves who named it as such.
Leaded fuel was marketed as Ethyl, a joint model of Commonplace Oil and Common Motors.

Makes an attempt at regulation
In Could 1925, the U.S. Public Well being Service requested GM, Commonplace Oil and public well being scientists to attend an open listening to on leaded gasoline in Washington. The difficulty, based on GM and Commonplace, concerned refinery security, not public well being. Frank Howard of Commonplace 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 literally thousands 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 the right way to discover that info, and the Public Well being Service, below strain from the auto and oil industries, canceled a second day of public hearings that will have mentioned safer gasoline components like ethanol, iron carbonyl and catalytic reforming.
By 1926, the Public Well being Service introduced that they’d “no good purpose” to ban leaded gasoline, though inner memos complained that their analysis was “half baked.”
As leaded gasoline fell out of use, lead ranges in individuals’s blood fell as properly.

The rise and fall of leaded gasoline
Leaded gasoline went on to dominate gasoline markets worldwide. Researchers have estimated that many years of burning leaded gasoline brought on tens of millions of untimely deaths, monumental declines in IQ ranges and plenty of different related social issues.
Within the Nineteen Sixties and Nineteen Seventies, the general public well being case in opposition to leaded gasoline reemerged. A California Institute of Know-how geochemist, Clair Cameron Patterson, was discovering it tough to measure lead isotopes in his laboratory as a result of lead from gasoline was in every single place and his samples had been consistently 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 power lead insult.”
In parallel, by the Nineteen 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 issues continued to construct within the Nineteen Seventies and Eighties when College of Pittsburgh pediatrician Herbert Needleman ran research linking excessive ranges of lead in youngsters with low IQ and different developmental issues. Each Patterson and Needleman confronted robust partisan assaults from the lead business, 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 creating nations after that. In August 2021, the final nation on the planet to promote leaded fuel, Algeria, banned it.
A century of leaded gasoline has taken tens of millions of lives and to today leaves the soil in lots of cities from New Orleans to London poisonous.
The leaded gasoline story gives a sensible instance of how business’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 powerful media protection of well being and environmental points to counter these dangers.
