G.M. scientists discover the anti-knock properties of tetraethyl lead gasoline.
General Motors scientists in 1921 discovered the anti-knock properties of tetraethyl lead as an additive to gasoline. By 1923, many American motorists would be driving into service stations and saying, “Fill ‘er up with Ethyl.”
Early internal combustion engines often suffered from a severe “knocking,” the out-of-sequence detonation of the gasoline-air mixture in a cylinder. The constant shock added to exhaust valve wear and frequently damaged engines.
Automobiles powered with gasoline had been the least popular models at the November 1900 first U.S. auto Show in New York City’s Madison Square Garden.
General Motors chemists Thomas Midgely Jr. and Charles F. Kettering tested many gasoline additives, including arsenic.
On December 9, 1921, after five years of lab work to find an additive to eliminate pre-ignition “knock” problems of gasoline, General Motors researchers Thomas Midgely Jr. and Charles Kettering discovered the anti-knock properties of tetraethyl lead.
Early experiments at GM examined the properties of knock suppressors such as bromine, iodine and tin — comparing these to new additives such as arsenic, sulfur, silicon and lead.

When the two chemists synthesized tetraethyl lead and tried it in their one-cylinder laboratory engine, the knocking abruptly disappeared. Fuel economy also improved. “Ethyl” vastly improved gasoline performance.
“Ethylizers” debut in Dayton
Although being diluted to a ratio of one part per thousand, the lead additive yielded gasoline without the loud, power-robbing knock. With other automotive scientists watching, the first car tank filled with leaded gas took place on February 2, 1923, at the Refiners Oil Company service station in Dayton, Ohio.
In the beginning, GM provided Refiners Oil Company and other service stations special equipment, simple bolt on adapters called “Ethylizers” to meter the proper proportion of the new additive.
“By the middle of this summer you will be able to purchase at approximately 30,000 filling stations in various parts of the country, a fluid that will double the efficiency of your automobile, eliminate the troublesome motor knock, and give you 100 percent greater mileage,” Popular Science Monthly reported in 1924.
By the late 1970s, public health concerns resulted in the phase-out of tetraethyl lead in gasoline, except for aviation fuel.
Anti-knock gasoline containing a tetraethyl lead compound also proved vital for aviation engines during World War II, even as danger from the lead content increasingly became apparent.
Powering Victory in World War II
Aviation fuel technology was still in its infancy in the 1930s. The properties of tetraethyl lead proved vital to the Allies during World War II. Advances in aviation fuel increased power and efficiency, resulting in the production of 100-octane aviation gasoline shortly before the war.
Phillips Petroleum – later ConocoPhillips – was involved early in aviation fuel research and had already provided high gravity gasoline for some of the first mail-carrying airplanes after World War I.
Phillips Petroleum produced tetraethyl leaded aviation fuels from high-quality oil found in Osage County, Oklahoma, oilfields.
Phillips Petroleum produced aviation fuels before it produced automotive fuels. The company’s gasoline came from the high-quality oil produced from Oklahoma’s Seminole oilfields and the 1917 Osage County oil boom.
Although the additive’s danger to public health was underestimated for decades, tetraethyl lead has remained an ingredient of 100 octane “avgas” for piston-engine aircraft.
Tetraethyl lead’s Deadly Side
Leaded gasoline was extremely dangerous from the beginning, according Deborah Blum, a Pulitzer-Prize winning science writer. “GM and Standard Oil had formed a joint company to manufacture leaded gasoline, the Ethyl Gasoline Corporation,” she noted in a January 2013 article. Research focused solely on improving the formula, not on the danger of the lead additive.
A 1932 magazine advertisement promoted the Ethyl Gasoline Corporation fuel additive as a way to improve high-compression engine performance.
“The companies disliked and frankly avoided the lead issue,” Blum wrote in “Looney Gas and Lead Poisoning: A Short, Sad History” at Wire.com. “They’d deliberately left the word out of their new company name to avoid its negative image.”
In 1924, dozens were sickened and five employees of the Standard Oil Refinery in Bayway, New Jersey, died after they handled the new gasoline additive.
By May 1925, the U.S. Surgeon General called a national tetraethyl lead conference, Blum reported, and an investigative task force was formed. Researchers concluded there was ”no reason to prohibit the sale of leaded gasoline” as long as workers were well protected during the manufacturing process.
So great was the additive’s potential to improve engine performance, the author notes, by 1926 the federal government approved continued production and sale of leaded gasoline. “It was some fifty years later – in 1986 – that the United States formally banned lead as a gasoline additive,” Blum added.
By the early 1950s, American geochemist Clair Patterson discovered the toxicity of tetraethyl lead; phase-out of its use in gasoline began in 1976 and was completed by 1986. In 1996, EPA Administrator Carol Browner declared, “The elimination of lead from gasoline is one of the great environmental achievements of all time.”

Lucky life of John Steele and America’s earliest petroleum riches.
John Washington Steele’s good fortune began on December 10, 1844, when Culbertson and Sarah McClintock adopted him as an infant. The McClintocks also adopted his sister Permelia, bringing both home to the farm along Oil Creek in Venango County, Pennsylvania.
Fifteen years later, the U.S. petroleum industry began with an 69.5-foot-deep oil discovery at nearby Titusville, the first oil well drilled commercially for distilling into kerosene (also called coal oil).
The Pennsylvania oil regions that had been revealed at Oil Creek made the widow McClintock a fortune in royalties. When she died in a kitchen fire in 1864, Mrs. McClintock left her oil wealth to her only surviving child Johnny, who inherited $24,500 at age 20.
John Washington Steele of Venango County, Pennsylvania, inherited oil riches.
Johnny also inherited his mother’s 200-acre farm along Oil Creek between what is now Rynd Farm and Rouseville. The farm already included 20 producing oil wells yielding $2,800 in royalties every day.
“Coal Oil Johnny” Steele would earn his name in 1865 after such a legendary year of extravagance that years later, according to the New York Times.
“In his day, Steele was the greatest spender the world had ever known,” the newspaper proclaimed. “He threw away $3,000,000 in less than a year.”
Philadelphia journalists coined the name “Coal Oil Johnny” for him, reportedly because of his attachment to a custom carriage that had black oil derricks spouting dollar symbols painted on its red doors. He later confessed in his autobiography:
I spent my money foolishly, recklessly, wickedly, gave it away without excuse; threw dollars to street urchins to see them scramble; tipped waiters with five and ten dollar bills; was intoxicated most of the time, and kept the crowd surrounding me usually in the same condition.

Of course, such wealth could not last forever. The rise and fall of Coal Oil Johnny, who died in modest circumstances in 1920 at age 76, will linger in petroleum history.
In 2010, the Atlantic magazine published “The Legend of Coal Oil Johnny, America’s Great Forgotten Parable,” an article surprisingly sympathetic to his riches to rags story. It describes the country’s fascination with the earliest economic booms brought by “black gold” discoveries in Pennsylvania.
“Before J.R. Ewing, or the Beverly Hillbillies, or even John D. Rockefeller, there was Coal Oil Johnny,” noted the October 18 feature story.
“He was the first great cautionary tale of the oil age — and his name would resound in popular culture for more than half a century after he made and lost his fortune in the 1860s.”

For generations after the peak of his career, Johnny was still so famous that any major oil strike – especially the January 1901 gusher at Spindletop Hill in Beaumont, Texas, “brought his tales back to people’s lips,” noted the magazine article, citing Brian Black, a historian at Pennsylvania State University.
“It was wealth from nowhere,” Black explained. “Somebody like that was coming in without any opportunity or wealth and suddenly has a transforming moment. That’s the magic and it transfers right through to the Beverly Hillbillies and the rest of the mythology.”
“Coal Oil Johnny” was a legend and like all legends, “he became a stand-in for a constellation of people, things, ideas, feelings and morals – in this case, about oil wealth and how it works,” he added.
John Washington Steele died in Nebraska in 1920.
“He made and lost this huge fortune – and yet he didn’t go crazy or do anything terrible. Instead, he ended up living a regular, content life, mostly as a railroad agent in Nebraska,” the 2010 Atlantic article concluded. “Surely there’s a lesson in that for the millions who’ve lost everything in the housing boom and bust.”
John Washington Steele’s Venango County home, relocated and restored by Pennsylvania’s Oil Region Alliance of Business, Industry & Tourism, stands today in Oil Creek State Park, just off Route 8, north of Rouseville.
On Route 8 south of Rouseville is the still-producing McClintock No. 1 oil well. “This is the oldest well in the world that is still producing oil at its original depth,” proclaims the Alliance. “Souvenir bottles of crude oil from McClintock Well Number One are available at the Drake Well Museum, outside Titusville.”

Designed for different fuels, 19th-century lamps burned many fuels, including rapeseed oil, lard, whale oil, and camphene — the distilled spirits of turpentine. Another popular fuel was “burning fluid,” a volatile combination of distilled spirits of turpentine and alcohol with camphor oil added for aroma.
Until replaced by the safer lamp fuel kerosene, two-wicked burning-fluid lamps provided light for much of America.
The burning fluid mixture required a double burner but no chimney, according to Ron Miller, a self-taught tinsmith and “hands-on historian.” He became fascinated by the designs of these early illuminating lamps.
Jim Miller’s 19th century lamp tin recreations, left to right: a whale oil burner; an 1842 patented lard oil burner; a “Betty Lamp” fueled by fat; and a typical burning fluid two-spout lamp.
“This adventure has deepened my appreciation for past craftsmanship and the intelligence of common place things in early America,” explained Miller in his 2012 For the love of History blog. “Besides, now I have all this cool stuff to play (teach) with.”
The key to learning about early to mid-19th century oil lamps was to study their burners, Miller noted (seeCamphene to Kerosene Lamps), adding, “each type of fuel needed a specific style of burner to give the best light.”
Although most of the fuels have become obsolete, Miller “wanted to faithfully replicate the burners, in order to understand how they evolved,” he said, adding, “For the time being, substitute fuels would have to do.”
Miller fashioned tin into period lamp designs, including one fueled by fat — a “Betty Lamp” that “has an ancestry extending clear back to the Romans but had been improved on over time.” He also recreated a whale oil lamp, circa 1850, and a patented lard oil burner of 1842 (the lard needed to be warmed, to improve its fluidity).
Miller also created a lard oil lamp using a burner patent from 1842.
“These tubes never extend down past the mounting plate and never have slots for wick adjustment. Apparently, any heat added to the fuel caused an accumulation of gases,” he noted. Most surviving original burners have little covers to snuff out the flame and keep the fuel from evaporating. Newspapers also reported the danger of flash fires during refueling.
“The style of lamp I chose to replicate is sometimes called a petticoat lamp by collectors for the flared shape of the base. Such lamps are often mislabeled as Whale Oil lamps but the difference is obvious once you know your burners,” Miller concluded about his replica.
“In case you wondered, my lamp burns modern lamp oil as I don’t need to kill myself in the pursuit of history,” the tinsmith added.

The gas that would not burn — and the professor who in 1905 extracted helium from a natural gas well.
Drilling for natural gas in May 1903, an exploratory well drilled by Gas, Oil and Developing Company found natural gas beneath William Greenwell’s farm near Dexter, Kansas. The discovery came as the company drilled into a geologic formation that produced “a howling gasser” that would not burn.
