Carbon Black & Oilfield Crayons

Crayola — a 1903 petroleum product named for the French word for chalk, craie, and English adjective oily, oleaginous.


Petroleum has provided products worldwide, with some hiding in plain sight. For Pennsylvania’s Benny & Smith Company, common oilfield paraffin changed the company’s future by coloring children’s imaginations. Before inventing Crayola crayons, the partners patented a “dustless chalk” popular with teachers, a red oxide for paints, and Staonal — “stay-on-all” — the blackest of all markers. 

Three decades after America’s first oil well at Titusville, Pennsylvania, Crayola crayons began with an 1881 refining patent by Edwin Binney to make carbon black, an intensely black pigment. Binney and partner C. Harold Smith had launched their company in Easton to sell inks, black polishes, and a chalk for schoolroom blackboards.

Binney & Smith Company received an 1891 patent for an “Apparatus for the Manufacture of Carbon Black,” which produced a fine, soot-like black pigment — far better than any other in use.

Pennsylvania’s booming oilfields would prove key to success, beginning with using natural gas in a patented “Apparatus for the Manufacture of Carbon Black.” Binney & Smith Company later would add oilfield paraffin — the bane of oil producers since it clogged wells — and mix in colors to create a petroleum product named Crayola.

Manufacturing Carbon Black

On May 28, 1891, Binney received a patent for the company’s method to efficiently produce a fine, soot-like substance  more intensely black than any other pigment in use at the time.

“The objects of my invention are to manufacture lamp-black from oil in an improved and economical manner, whereby waste of the product and unnecessary expenditure of labor are avoided,” Binney noted in his patent application.

His patent (No. 453,140) proclaimed a process to “manufacture carbon-black from gas in such a manner as to obtain improved quality of black which shall have the soft flaky texture of lamp-black made in ordinary ways.”

The young U.S. petroleum industry, rapidly expanding its refineries to fuel kerosene for lamps, supplied Binney & Smith Company the oil and natural gas feedstock for the company’s carbon black. The heat and smoke resulting from the burning gas was directed to cool in revolving metal drums.

The company refining process produced a fine, soot-like substance of incredible blackness — a better pigment than any other then used. Binney & Smith’s carbon black received an award at the 1900 Paris Exposition, a world’s fair of the century’s achievements.

It was not long before the inventors mixed their carbon black product with oilfield paraffin and other waxes to introduce a paper-wrapped black crayon marker for crates and barrels. The marker was promoted as being able to “stay on all” and accordingly named “Staonal.”

Resulting from an 1891 carbon black patent, Binney & Smith added oilfield paraffin to produce a black marker. Staonal is still sold.

Staonal became a highly successful company product, but was too laden with carbon black to be safe for use by children. Earlier, the company had found success manufacturing “dustless chalk” for schoolrooms and a red iron oxide for a red paint farmers used on barns.  

Classroom Chalk

Although they longed for color, students in Alice Stead Binney’s classroom had to settle for dustless chalk. In fact, An-Du-Septic dustless chalk was so popular among turn-of-the-century teachers that it won a Gold Medal at the 1904 World’s Fair in St. Louis.

Teachers like Alice loved the tidy new product, but their choices were limited. Pencils of the day were primitive, with square “leads” made from a variety of clays, slates, and graphite. Color writing implements were the toxic and expensive imports of artists, best kept away from schoolchildren.

Alice’s husband Edwin, and his cousin, C. Harold Smith, created An-Du-Septic chalk as a consequence of expanding their pigment business into the sideline production of slate pencils for schools.

In Easton, the Binney & Smith Company, formerly the Peekskill Chemical Works, was best known for its production of red iron oxide and carbon black for paints, inks, and stove and shoe polishes. That would change.

Slate pencils and the very successful An-Du-Septic dustless chalk nonetheless put Binney & Smith salesmen into America’s classrooms. The company’s sales force listened to teachers and learned there would be a ready market for inexpensive, non-toxic, brightly colored crayons.

“Crayola” from Oilfield Paraffin

By 1903, Binney & Smith was ready to launch a new product that would change childhood forever. Alice Binney provided the historic name by combining the French word for chalk, craie, with an English adjective meaning oily, oleaginous, creating Crayola.

Manufacturing was based on small batches of carefully measured and hand-mixed pigments, paraffin, talc and other waxes. Paper labels were individually rolled by hand and pasted onto each crayon.

The finished products were hand packed into individual boxes and shipped in wooden crates. Sixteen Crayola crayons sold for 10 cents; eight for 5 cents: red, yellow, orange, green, blue, violet, black, and brown. Crayola was an instant hit.

Binney and Smith produced the first box of eight Crayola crayons in 1903 — red, orange, yellow, green, blue, violet, brown, and black.

The company’s proprietary formulas remain a closely guarded secret as demand for its crayons has continued to grow around the world. Production capacity reportedly is more than four million crayons every day, thanks to oilfield paraffin from distant petroleum refineries delivered to Crayola’s Easton factory in railroad tank cars.

In January 2007, Binney & Smith became Crayola LLC in recognition of the company’s number one brand. The company is now known as Crayola. Crayola has grown to become a $500 million dollar a year business — a successful union of the petroleum industry to the colorful world of children’s imaginations. 

“This organizational and name change showcases the company’s Crayola brand, sold by Binney & Smith since 1903,” explained the company, which also opened a museum in Easton. Crayola is sold in more than 80 countries, “and represents innovation, fun, kids and quality.”

As paraffin continued to find its way into more products (see The Crude History of Mabel’s Eyelashes), in 1912, Binney & Smith’s carbon black was used for the first time to make black tires.

Carbon Black Hits the Road

Until carbon black was added to improve durability, auto tires were white. In 1839, bankrupt Philadelphia hardware merchant and erstwhile inventor Charles Goodyear accidentally dropped rubber and sulfur on a hot stove top. The rubber charred like leather yet remained elastic, a discovery that led to “vulcanization.”

With the new process, natural rubber could be transformed into an industrial product with innumerable uses. Goodyear’s famous lawyer, Daniel Webster, praised his client’s invention. “It introduces quite a new material into the manufacture of the arts, that material being nothing less than elastic metal,” Webster proclaimed.

Automobile tires were the ideal application for this new product. Between 1895 and 1905, more than 77,000 new automobiles were registered in the United States (See Cantankerous Combustion — First U.S. Auto Show).

The tires of this 1904 Oldsmobile Model N Touring Runabout were not chosen for their color. Until B.F. Goodrich introduced “carbon black” into the vulcanizing process in 1910, auto tires were white.

The nation’s maximum speed limit in most cities was 10 mph, and automobile tires were white. Natural rubber pigments and zinc oxide used in the manufacturing process gave tires their color.

In 1910, the B.F. Goodrich Company found that adding carbon black to the vulcanizing process dramatically improved strength and durability. The material came from controlled combustion of both oil and natural gas. Its use in tires created an immense market — initially consuming one pound of carbon black for each two pounds of rubber.

As America’s automobile industry grew, so did demand for tires and for carbon black. By 1931, Texas was producing more than 200 million pounds of carbon black annually from just 31 plants — 75 percent of America’s total.

Today, most of America’s carbon black is still produced in Texas and Louisiana. Demand remains closely associated with auto tires. Cabot Corporation — founded in Pennsylvania in 1882 — is the largest U.S. producer of the intensely black petroleum product. By 2024, the company operated 43 manufacturing facilities in more than 20 countries.

Standard Oil Whiting Refinery

Standard Oil scientists patented the “thermal cracking” process.


Beginning in the 1890s, the Whiting refinery of Standard Oil Company of Indiana first produced kerosene for lamps and later gasoline for autos to meet growing consumer demand.

Seventeen miles east of Chicago, Standard Oil Company of New Jersey began construction on a massive refinery complex in early May 1889. Using advanced refining processes introduced by John D. Rockefeller, it would become the largest in the United States.

Once operated by Amoco, the refinery in Whiting, Indiana, was acquired by the British Petroleum Company in 1998. After the acquisition, British Petroleum became BP Amoco, a name shorted to BP in 2001 after mergers with ARCO and Castrol.

The BP brand also changed to lower-case bp, often with the tagline “beyond petroleum” and a stylized yellow and green sun.  By 2023, the 1,400-acre Whiting plant refined 435,000 barrels of oil per day.

Refining “Sour Crude”

About one month after construction of the then 235-acre refinery began, Rockefeller established a locally based subsidiary by incorporating Standard Oil Company of Indiana on June 18, 1889. The new company began processing oil at its Whiting refinery within a year.

In its early years, the Indiana refinery processed a sulfurous “sour crude” from the Lima, Ohio, oilfields — transported on Rockefeller controlled railroads. Most Americans, already putting out their tallow candles to buy lamps fueled with whale oil, lard, or the less costly but volatile camphene, embraced a new fuel — “rock oil” soon brought skyrocketing public demand.

Rockefeller had purchased considerable amounts of production from the Lima oilfield at bargain prices. Most experts in the new petroleum industry believed the thick oil virtually worthless. It could not be refined for a profit. The Whiting refinery, using a newly patented method, efficiently processed Ohio sour oil into high-quality kerosene.

Although gasoline was a minor by-product, two brothers in Massachusetts were building a gasoline-powered horseless carriage at about the time the refinery produced its first 125 railroad tank cars filled with kerosene. The gas-powered automobile helped relaunch the petroleum industry — see Cantankerous Combustion – 1st U.S. Auto Show.

The Standard Oil refinery in Whiting, Indiana, became the company’s most productive. Owned by BP since 1998, it has remained the largest U.S. refinery. Whiting has been home to the Northwest Indiana Oilmen since 2012.

“By the mid-1890s, the Whiting plant had become the largest refinery in the United States, handling 36,000 barrels of oil per day and accounting for nearly 20 percent of the total U.S. refining capacity” noted historian Mark R. Wilson in the Encyclopedia of ChicagoInitially it consisted of just a single facility, adds a company history on the Amoco website.

Support the American Oil & Gas Historical Society

Crude oil was processed into products that people and business needed: axle grease for industrial machinery, paraffin wax for candles, kerosene for home lighting.

“The company grew. By the early 1900s it was the leading provider of kerosene and gasoline in the Midwest” noted Wilson on the website. “Kerosene sales would eventually falter. But with car ownership booming across the United States, demand for gasoline would only go up and up.”

More Midwest Refineries

By 1910, the refinery was connected by pipeline to oilfields in Kansas and Oklahoma, as well as Ohio and Indiana. The Whiting facility employed 2,400 workers a year later when Rockefeller was forced to break up his petroleum empire. Standard Oil of Indiana, with offices in downtown Chicago, emerged as an independent company.

Rockefeller’s Whiting scientists earlier had patented the process they called “thermal cracking” that doubled the amount of gasoline made from a barrel of oil and also boosted the octane rating. Crude oil hydrocarbons were subjected to high heat, “breaking down long-chained, higher-boiling hydrocarbons into shorter-chained, lower-boiling hydrocarbons,” according to Science Direct.

Standard Oil’s revolutionary process, which became standard practice in the refining industry, helped avert a gasoline shortage during World War I. To find its own oil supplies, Standard Oil of Indiana began its own exploration and production business, Stanolind.

In 1922, Standard Oil absorbed the American Oil Company, founded in Baltimore in 1910, and began branding products as Amoco, which later would become its company name. By 1952, Amoco was ranked as the largest domestic oil company.

During the second half of the twentieth century, the U.S. refining industry became more concentrated in Texas, Louisiana, and California.

“The Chicago region became somewhat less important as an oil-processing center than it had been during the previous 60 years,” historian Mark Wilson concluded. “Still, the area remained home to some large refineries. The largest of these plants was the one at Whiting – the same facility that had brought refining to Chicago in 1890.” 

Across the border from Indiana, three major Illinois refineries also process oil in the Chicago area.  At the end of 2021, the Citgo refinery in Lemont processed 177,000 barrels of oil a day; the Joliet refinery owned by ExxonMobil processed 248,000 barrels of oil a day; and the Robinson refinery of Marathon Petroleum Company processed 192,000 barrels of oil a day (with a reported capacity for 253,000 barrels).

Wood River Refining Museum

A fourth refinery located in southern Illinois was constructed in 1918 by Shell. The Wood River Refinery has operated north of St. Louis along the Mississippi River. 

The refinery, owned since 2013 by ConocoPhillips, has remained that company’s largest, processing 380,000 barrels of oil daily into millions of gallons of gasoline/fuel — and thousands of barrels of asphalt. The refinery also has its own museum.

“The Wood River Refinery History Museum is located in front of the Conoco-Phillips Refinery on Highway 111 in Wood River, Illinois,” the museum notes on its website. “There are four buildings in our complex, so to see most of our collection, plan on spending some time.”

The Crude History of Mabel’s Eyelashes

How oilfield paraffin created Vaseline — and Maybelline.


Few associate 1860s oil wells with women’s eyes, but they are fashionably related. From paraffin to Vaseline, this is the story of how the goop that accumulated around the sucker rods of America’s earliest oil wells made its way to eyelashes.

In 1865, a 22-year-old Robert Chesebrough left the prolific oilfields of Pithole and Titusville, Pennsylvania, to return to his Brooklyn, New York, laboratory. He carried samples of a waxy substance that clogged wellheads. He already had dabbled in the “coal oil” business with experiments on refinery processes.

Chesebrough’s laboratory expertise included distilling cannel coal into kerosene (coal oil), a lamp fuel in high demand among consumers. He also knew of the process for refining crude oil into a kerosene.

So, when Edwin L. Drake completed the first U.S. oil well in August 1859, Chesebrough was among those who rushed to Pennsylvania oilfields to make his fortune. 

“Now commenced a scene of excitement beyond description,” reported Scientific American. “The Drake well was immediately thronged with visitors arriving from the surrounding country, and within two or three weeks thousands began to pour in from the neighboring States.”

Chesebrough was convinced he too could get rich from the “black gold” of Pennsylvania’s oilfields.

Oilfield Sucker Rod Wax

In the midst of the Venango County exploration and production chaos, the young chemist noted a waxy buildup often confounded drilling.  This paraffin-like substance clogged the wellhead and drew curses from riggers who had to stop drilling to scrape it away.

Robert Chesebrough consumed a spoonful of Vaseline each day and lived to be 96. This early bottle from the collection of the Drake Well Museum in Titusville, Pennsylvania.

The only virtue of this goopy oilfield “sucker rod wax” was as an immediately available first aid for the abrasions, burns, and other wounds routinely afflicting the crews.

Paraffin to Vaseline

Chesebrough abandoned his notion of drilling a gusher and returned to New York, where he worked in his laboratory to purify the troublesome sucker-rod wax, which he dubbed “petroleum jelly,” one of America’s earliest petroleum products

By August 1865, Chesebrough had filed the first of several patents “for purifying petroleum or coal oils by filtration.”

The chemist experimented with the analgesic effects of his extract by inflicting minor cuts and burns on himself, then applying the purified petroleum jelly. He also gave it to Brooklyn construction workers to treat their minor scratches and abrasions.

After refining oilfield wax, Chesebrough experimented by inflicting minor cuts and burns on himself, then applying his petroleum balm.

On June 4, 1872, Chesebrough patented a new product that would endure to this day – “Vaseline.” His paraffin to Vaseline patent extolled new balm’s virtues as a leather treatment, lubricator, pomade, and balm for chapped hands. Chesebrough soon had a dozen wagons distributing the product around New York. 

Customers used the “wonder jelly” creatively: treating cuts and bruises, removing stains from furniture, polishing wood surfaces, restoring leather, and preventing rust. Within 10 years, Americans were buying it at the rate of a jar a minute

An 1886 issue of Manufacture and Builder even reported, “French bakers are making large use of vaseline in cake and other pastry. Its advantage over lard or butter lies in the fact that, however stale the pastry may be, it will not become rancid.”

Flavor notwithstanding, Chesebrough himself consumed a spoonful of Vaseline each day. He lived to be 96 years old. It was not long before thrifty young ladies found another use for Vaseline.

Mabel’s Eyelashes

As early as 1834, the popular book Toilette of Health, Beauty, and Fashion had suggested alternatives to the practice of darkening eyelashes with elderberry juice or a mixture of frankincense, resin, and mastic.

“By holding a saucer over the flame of a lamp or candle, enough ‘lamp black’ can be collected for applying to the lashes with a camel-hair brush,” the book advised.

Chesebrough’s female customers found that mixing lamp black with Vaseline using a toothpick made an impromptu mascara. Some sources claim that Miss Mabel Williams in 1913 employed just such a concoction preparing for a date. Williams was dating Chet Hewes.

Women were using Vaseline to make mascara by 1915. Cosmetic industry giant Maybelline traces its roots to the petroleum product. “What a Difference Maybelline Does Make” magazine ad from 1937.

Perhaps using coal dust or some other readily available darkening agent, she applied the mixture to her eyelashes for a date. Her brother, Thomas Lyle Williams, was intrigued by her method and decided to add Vaseline in the mixture, noted a Maybelline company historian.

A more reliable version of the story — told by Williams’ grandniece Sharrie Williams — has Mabel demonstrating “a secret of the harem” for her brother.

“In 1915, when a kitchen stove fire singed his sister Mabel’s lashes and brows, Tom Lyle Williams watched in fascination as she performed what she called ‘a secret of the harem’ mixing petroleum jelly with coal dust and ash from a burnt cork and applying it to her lashes and brows,” Sharrie Williams explained in her 2007 book, The Maybelline Story and the Spirited Family Dynasty Behind It.

“Mabel’s simple beauty trick ignited Tom’s imagination and he started what would become a billion-dollar business,” concluded Williams.

Silent screen stars like Theda Bara, right, helped glamorize Maybelline mascara. By the 1930s, the paraffin to Vaseline to mascara concoction was available at five-and-dime stores for 10 cents a cake.

Inspired by his sister’s example, he began selling the mixture by mail-order catalog, calling it “Lash-Brow-Ine” (an apparent concession to the mascara’s Vaseline content). Women loved it.

When it became clear that Lash-Brow-Ine had potential, Williams, doing business in Chicago as Maybell Laboratories, on April 24, 1917, trademarked the name as a “preparation for stimulating the growth of eyebrows and eyelashes.”

With sales exceeding $100,000 by 1920, Williams renamed the mascara Maybelline in honor of his sister, who worked with him in his Chicago office — and married Chet Hewes in 1926.

Theda Bara – an anagram for “Arab Death” – and Pola Negri, each with daring eye makeup, smoldered in packed theaters across the country.

Maybelline trumpeted its mail-order mascara in movie and confession magazines as well as Sunday newspaper supplements. Sales continued to climb. By the 1930s, Maybelline mascara was available at the local five-and-dime store for 10 cents a cake.

Crayola Crayons

Paraffin from early U.S. oilfields also proved key the phenomenal success of business partners Edwin Binney and C. Harold Smith, who in 1891 patented an “Apparatus for the Manufacture of Carbon Black.”

Binney and Smith mixed carbon black with oilfield paraffin and other waxes to introduce a paper-wrapped black crayon marker for crates and barrels.

By 1903, the Binney & Smith Company of Easton, Pennsylvania, was adding colors for a new product, “Crayola” crayons. Learn more about their petroleum products in Carbon Black & Oilfield Crayons.

Camphene to Kerosene Lamps


In the early 19th century, lamp designs burned many different fuels, including rapeseed oil, lard, and whale oil rendered from whale blubber (and the more expensive spermaceti from the heads of sperm whales), but most Americans could only afford light emitted by animal-fat, tallow candles.

By 1850, the U.S. Patent Office recorded almost 250 different patents for all manner of lamps, wicks, burners, and fuels to meet growing consumer demand for illumination. At the time, most Americans still lived in almost complete darkness when the sun went down. (more…)

Nylon, a Petroleum Polymer

Revolutionary DuPont lab product first used commercially in 1938 for toothbrush bristles.


The world’s first synthetic fiber was the petroleum product “Nylon 6,” discovered in 1935 by a DuPont chemist who produced the polymer from chemicals found in oil.

DuPont Corporation foresaw the future of “strong as steel” artificial fibers. The chemical conglomerate had been founded in 1802 as a Wilmington, Delaware, manufacturer of gunpowder. The company would become a global giant after its scientists created durable and versatile products like nylon, rayon and lucite.

“Women show off their nylon pantyhose to a newspaper photographer, circa 1942,” noted historian Jennifer S. Li in “The Story of Nylon – From a Depressed Scientist to Essential Swimwear.” Photo by R. Dale Rooks (1917-1954).

The world’s first synthetic fiber — nylon — was discovered on February 28, 1935, by a former Harvard professor working at a DuPont research laboratory. Called Nylon 6 by scientists, the revolutionary carbon-based product came from chemicals found in petroleum.

Man-made fiber Nylon 6 illustration of its six carbon atoms per molecule.

Chemists called the man-made fiber Nylon 6 because chains of adipic acid and hexamethylene diamine each contained six carbon atoms per molecule.

Professor Wallace Carothers had experimented with artificial materials for more than six years. He previously discovered neoprene rubber (commonly used in wet suits) and made major contributions to understanding polymers — large molecules composed in long chains of repeating chemical structures.

Polymer Chains

Carothers, 32, created fibers when he combined the chemicals amine, hexamethylene diamine, and adipic acid. His experiments formed polymer chains using a process in which individual molecules joined together with water as a byproduct. But the fibers were weak.

A PBS series, A Science Odyssey: People and Discoveries, in 1998 noted Carothers’ breakthrough came when he realized, “the water produced by the reaction was dropping back into the mixture and getting in the way of more polymers forming. He adjusted his equipment so that the water was distilled and removed from the system. It worked!”

DuPont named the petroleum product nylon — although chemists called it Nylon 6 because the adipic acid and hexamethylene diamine each contain six carbon atoms per molecule.

1938 ad for petroleum product nylon bristles on toothbrushes.

“Until now, all good toothbrushes were made with animal bristles,” noted a 1938 ad.

Each man-made molecule consists of 100 or more repeating units of carbon, hydrogen, and oxygen atoms, strung in a chain. A single filament of nylon may have a million or more molecules, each taking some of the strain when the filament is stretched.

There’s disagreement about how the product name originated at DuPont.

“As to the word nylon, it’s actually quite arbitrary. DuPont itself has stated that originally the name was intended to be No-Run (that’s run as in the sense of the compound chain of the substance unravelling), but at the time there was no real justification for the claim, so it needed to be changed,” noted Chris Nickson in a 2017 website post, Where Does the Name Nylon Originate?

Toothbrush Bristles

The first commercial use of this revolutionary petroleum product was for toothbrushes.

On February 24, 1938, the Weco Products Company of Chicago, Illinois, began selling its new “Dr. West’s Miracle-Tuft” — the earliest toothbrush to use synthetic DuPont nylon bristles.

First used for toothbrush bristles, nylon women’s stockings were promoted in a DuPont 1948 ad.

Americans will soon brush their teeth with nylon — instead of hog bristles, declared an article in the New York Times. “Until now, all good toothbrushes were made with animal bristles,” explained a 1938 Weco Products advertisement in Life magazine.

“Today, Dr. West’s new Miracle-Tuft is a single exception,” the ad proclaimed. “It is made with EXTON, a unique bristle-like filament developed by the great DuPont laboratories, and produced exclusively for Dr. West’s.”

Pricing its toothbrush at 50 cents, the Weco Products Company guaranteed, “no bristle shedding.” Johnson & Johnson of New Brunswick, New Jersey, will introduce a competing nylon-bristle toothbrush in 1939.

Nylon Stockings

Although DuPont patented nylon in 1935, it was not officially announced to the public until October 27, 1938, in New York City.

A DuPont vice president unveiled the synthetic fiber — not to a scientific society or industry association — but to 3,000 Women’s Club members gathered at the site of the upcoming 1939 New York World’s Fair.

“He spoke in a session entitled ‘We Enter the World of Tomorrow,’ which was keyed to the theme of the forthcoming fair, the World of Tomorrow,” explained DuPont historian David A. Hounshell in a 1988 book.

The petroleum product was an instant hit, especially as a replacement for silk in hosiery. DuPont built a full-scale nylon plant in Seaford, Delaware, and began commercial production in late 1939.

The company purposefully did not register “nylon” as a trademark – choosing to allow the word to enter the American vocabulary as a synonym for “stockings.”

Women’s nylon stockings appeared for the first time at Gimbels Department Store on May 15, 1940. World War II would remove the polymer hosiery to make nylon parachutes and other vital supplies.

Nylon would become far and away the biggest money-maker in the history of DuPont. The powerful material from lab research led company executives to derive formulas for growth, according to Hounshell in The Nylon Drama.

“By putting more money into fundamental research, Du Pont would discover and develop ‘new nylons,’ that is, new proprietary products sold to industrial customers and having the growth potential of nylon,” Hounshell explained in his 1988 book.

Carothers did not live to see the widespread application of his work — in consumer goods such as toothbrushes, fishing lines, luggage and lingerie, or in special uses such as surgical thread, parachutes, or pipes — nor the powerful effect it had in launching a whole era of synthetics.

Devastated by the sudden death of his favorite sister in early 1937, Carothers committed suicide in April of that year. The DuPont Company would name its research facility after him.

As the DuPont website notes, the invention of nylon radically changed the way people dressed worldwide —  and rendered the term ‘silk stocking’ obsolete (and once an epithet directed at the wealthy elite).

Nylon’s success encouraged DuPont to adopt long-term strategies for products developed from basic research.

Standard Oil and the Kerosene Stove

“New Perfection” kerosene stoves competed with coal and wood-burning stoves in early 20th century rural kitchens.


In the early 1900s, a foundry in Cleveland, Ohio, began manufacturing and selling an alternative to coal or wood-burning cast iron stoves. Thanks to a marketing partnership with Standard Oil Company, millions of rural kitchens would cook with kerosene-burning stoves.

America’s energy future changed after 1859 when a new “coal oil” (kerosene) was refined from petroleum purposefully extracted from wells drilled near Oil Creek, Pennsylvania.

A Depression-era home cook cast iron stove.

A Cleveland foundry president in 1901 approached John D. Rockefeller about marketing a new, kerosene-fueled alternative to cast iron home stoves like this one.
