1851: Early refining emerges

Image: Cedrik Wesche

Just before the drilling boom, chemists like Samuel Kier developed small stills to refine crude oil into kerosene for lamps.

That innovation turned oil from a curiosity into a practical commodity. Kerosene replaced whale oil, making lighting cheaper and more widely available, and it created demand for a reliable crude supply.

On August 27, 1859, Drake Well near Titusville, Pennsylvania, drilled by Edwin L. Drake, became the first purposefully drilled commercial oil well in U.S. history.

This moment ignited the first true American oil boom. Suddenly, it was possible to produce large volumes of crude—not just collect surface seepage—and to refine it into useful fuels.

Word of the Drake success spread fast, and drilling spiked throughout Pennsylvania. Towns such as Titusville swelled almost overnight as wells and refineries spread along Oil Creek Valley.

Railroads extended into western Pennsylvania to transport oil across the country, embedding petroleum into America’s emerging industrial infrastructure.

By the 1890s and into the early 20th century, the rise of the automobile created growing demand for gasoline , which had previously been a relatively minor byproduct of crude oil refining.

This shift moved oil’s primary role away from lighting and industrial lubrication and toward transportation fuel , setting the stage for petroleum to dominate America’s energy needs in the decades that followed.

Following early successes, oil refining and distribution consolidated. Firms like Standard Oil Company rose to dominate refining, pipelines, and distribution networks.

At the same time, new oil fields and competition still challenged monopolies and spread oil wealth and infrastructure across more regions of the country.

1914–1945: Oil & war

Image: Roman

During both World War I and World War II, U.S. oil production and refining capacity became critical to the Allied war effort , fueling ships, vehicles, aircraft, and manufacturing.

That strategic role cemented oil’s position not only in industry but also in American global power, military strategy, and foreign policy.

1960: A global oil cartel forms

Image: Christian Harb

On September 14, 1960, the main oil‑exporting nations formed the Organization of the Petroleum Exporting Countries (OPEC) to coordinate oil production and influence prices globally.

Though initially limited in power, OPEC’s rise began to challenge American dominance , setting the stage for decades of geopolitical tension around oil supply.

1969: Santa Barbara oil spill

Image: matt brown

In early 1969, a blowout from an offshore drilling platform released tens of thousands of barrels of oil into the waters off California’s coast, devastating marine life and beaches.

The resulting public outrage helped trigger a surge in environmental awareness and regulation, marking a turning point in how the oil industry was perceived socially and politically.

1970–1973: Peak and decline

Image: Documerica

By 1970, U.S. conventional oil production reached its peak, but soon after began a decline as domestic fields matured and couldn’t keep up with the growing demand.

As American production fell, the country gradually became more reliant on foreign oil, a shift that would have major economic and political repercussions.

2000s–2010s: Top oil producer again

Image: engin akyurt

In the early 2000s, engineers refined techniques like hydraulic fracturing and horizontal drilling. This unlocked vast shale‑oil and shale‑gas reserves previously uneconomical to tap.

From about 2010 onward, U.S. crude oil production rose sharply, reversing decades of decline. By 2019, the country was producing at levels not seen since the early 1970s.

The light bulb

Delivering electricity to the masses was one of the greatest technological advances in human history. The mid-1800s saw great competition in this area, as inventors around the world raced to invent their own electric light. The first filament bulb was developed by British inventor Warren de la Rue in 1840, but his use of a platinum filament made it expensive and impractical.

A few years later, Joseph Swan in the UK and Thomas Edison in the US each independently invented bulbs using cheaper elements. However, Edison received a patent on his bulb in early 1880, slightly before Swan. The light bulb, an invention that quickly reached every home, revolutionized life around the world, led to the development of the electrical grid, and set the stage for our modern electricity-dependent society.

The telephone

In this modern era of emails and text messages, it can be hard to appreciate that the telephone was once revolutionary. The telegraph, the phone’s predecessor, only transmitted brief written messages. The telephone, however, allowed people to speak with one another in real time over long distances.

Inventor, scientist, and engineer Alexander Graham Bell invented the electric telephone in 1876. Although Bell was Scottish-born and also lived in Canada, he patented his invention in the US . The telephone was a game-changing technology that improved business efficiency, enabled instant global connections, and allowed emergencies to be reported as they occurred. It effectively made the world more connected and faster-paced.

The fire escape

Image: Lewis J Goetz

When we think of US inventions, the first things that come to mind are usually the light bulb or the telephone. But did you know that the modern fire escape was also a US innovation? Designed in 1887, this simple yet life-saving invention changed building safety forever.

In the late 1800s, fires were devastating cities across America. One woman, Anna Connelly, saw this horror up close and decided to do something about it. She designed an external iron staircase system, and in 1887, she patented it. At a time when women couldn’t even vote, Anna’s invention became a safety standard in most major cities, saving thousands of lives. Today her name is barely known, but next time you see a fire escape, remember the woman who made them possible.

The cash register

Image: Di Du

The first mechanical cash register for calculating and recording sales transactions was invented by saloonkeeper James Ritty following the American Civil War. He was looking for a way to stop cashiers from stealing, and finally patented his novel invention in 1879.

When a transaction was completed, Ritty's Incorruptible Cashier made a bell sound, and the amount was displayed on a large dial on the front of the machine. During each sale, a paper tape was hole-punched so the vendor could keep track of sales. Pretty ingenious, don’t you think?

Interchangeable parts

Standardized interchangeable parts for machines are now a staple of modern manufacturing, but it’s not a new idea. There’s evidence that thousands of years ago, ancient Carthage used them to build warships, and ancient China applied the idea to crossbows. Many centuries later, French experimentation with interchangeable musket parts inspired Thomas Jefferson.

In 1798, President George Washington and his Congress finally agreed to Jefferson’s idea of implementing the technology in America. They awarded a contract to Eli Whitney—the inventor of the cotton gin—to supply the government with 20,000 muskets. Whitney recognized the potential of developing firearms with identical parts and mechanisms. His advancements in interchangeable parts laid the foundation for modern manufacturing, enabling improved quality control, reduced costs, and faster production of goods.

The assembly line

For most of human history, manufactured goods were custom-made. Every model of a machine, piece of clothing, or tool was unique. The development of interchangeable parts was a huge advancement, but automobile manufacturer Ransom Olds took it a step further with the assembly line in 1901. By standardizing and automating many aspects of manufacturing, uniform goods could be created faster and at lower costs.

Olds’ vehicle, the Oldsmobile Curved Dash, became the first mass-produced car . His method was later adopted and perfected by Henry Ford, whose moving assembly line for the Model T in 1913 revolutionized manufacturing. Today, the assembly line combines human labor and automation to produce nearly every mass-market product on Earth. Many experts agree it was one of the most significant technological developments of the 20th century.

The airplane

People have always observed birds and insects and dreamed of flying. The Greeks told the story of Icarus and Daedalus, who crafted wings of wax and feathers; Leonardo da Vinci sketched and theorized flying machines, but it wasn’t until 1903 that the airplane became a reality in Kitty Hawk, North Carolina.

Wilbur and Orville Wright experimented with aeronautics for several years before achieving their successful first flight. A few years later, airplanes were first used in warfare. Within seven decades, their technology evolved and took us to the Moon. Today, the airplane is an indispensable technology that allows us to transport goods and people around the world in no time.

GPS

It’s hard to imagine life without GPS—but do you know how it began? When the Soviet Union launched Sputnik in 1957, American physicists realized they could track the satellite’s radio transmissions using the Doppler effect.

Soon after, the U.S. military began testing and launching the Navstar Global Positioning System satellites. In 1983, President Ronald Reagan approved GPS for civilian use, and by the start of the 21st century, GPS devices were widely available in vehicles and mobile phones . Today, GPS is an essential technology for business, travel, and military operations.

Personal computers

The first electronic general-purpose computer, ENIAC, was built in 1946 at the University of Pennsylvania. It occupied 1,800 square feet of floor space and weighed 30 tons. At the time, imagining a consumer-grade computer small enough to fit in every home would have seemed impossible. Yet, just one generation later, the impossible became reality.

Over the years, computers became smaller, cheaper, and more powerful than the ENIAC’s creators could have imagined. In 1971, John Blankenbaker developed the first PC, the Kenbak-1. Fifty years later, it is clear that personal computing has fundamentally shaped the modern world.

The internet

Revolutionary technologies such as the wheel, the internal combustion engine, the telephone, and the airplane have forever changed the way we travel and communicate. The internet is no exception; it gives people access to the entirety of human existence with just a few clicks.

In 1969, computer scientists at the Advanced Research Projects Agency (ARPA) created the first network connecting labs at UCLA and Stanford. Over time, their network expanded, connecting anyone with a device. Since then, the internet has revolutionized the way human beings access resources and share information.

E-mail

After the personal computer and the Internet, we only needed to invent a modern method of sending messages and letters to each other. The Advanced Research Projects Agency Network, known as ARPANET, sent the first email in 1971. Within five years, the majority of exchanges within the ARPANET community were via email.

With the introduction of attachments in the early 1990s, electronic mail became the fastest and easiest way to send information from point to point. By the start of the 21st century, email enabled people around the world to communicate quickly and inexpensively, and the technology quickly became one of the primary tools for global communications.

Magnetic resonance imaging

The impact of the MRI machine on medicine is invaluable. The principles behind nuclear magnetic resonance (NMR) have been known since at least the end of World War II. Yet, two researchers in the late 1960s and early 1970s recognized the potential of this technology to revolutionize medicine forever.

American chemist Paul Lauterbur and physician Raymond Damadian separately experimented with NMR in scanning for cancer cells. After publishing the promising results of their experiments, a patent was filed. By 1977, the first full-body scanner was developed. Since then, millions of lives have been saved by the MRI machine. For his contributions, Lauterbur was awarded the Nobel Prize in Physiology or Medicine in 2003.

George Washington had wooden teeth

Image: Todd Trapani

Washington suffered from dental problems throughout his adult life and did wear several sets of false teeth. However, he did not wear wooden ones.

They were made from materials like ivory, metal, and springs . The "wood" myth probably comes from the staining of ivory and from 19th-century caricatures.

2

Salem witches were burned at the stake

Image: Sofia Holmberg

We hold the long-standing belief that the accused Salem "witches" were burned like European witch victims.

However, in the Salem (and colonial New England) trials of 1692–1693, convicted witches were almost always executed by hanging ; burning at the stake was not the legal penalty under English law in the colonies.

Paul Revere rode and shouted, "The British are coming!" alone

Image: Mikhaël Noury

He may be riding alone in the Boston statue that represents the dramatic midnight ride in which he warned of the British troop movements.

But in reality, Revere was one of several riders who spread word of the British troop movements; Longfellow’s 1860 poem amplified and simplified the story, including the shouted line, which would have been unlikely among colonists.

Betsy Ross designed the first American flag

Image: Heather Newsom

We have heard again and again the myth that Betsy Ross stitched the first Stars and Stripes after being asked by George Washington. In reality, this tale grew from a family tradition promoted more than a century after 1776. Historians have found no contemporary documentation proving that she designed the first official flag.

The flag’s creation was likely more complex and collective. Ross has always remained a folk symbol, but there is no proof that she was the sole designer.

Mrs. O’Leary’s cow started the Great Chicago Fire

Image: raquel raq

The myth: a cow kicked over a lantern in Catherine O’Leary’s barn and caused the 1871 conflagration. The cow story originated in sensational newspaper reporting and later became part of folklore.

Investigations have never produced conclusive proof, and modern historians treat the O’Leary–cow tale as an unfair scapegoating and probably apocryphal. The fire’s precise origin remains a mystery.

"Molly Pitcher" was a famous woman who operated a cannon at Monmouth

Image: Foysal Razu

The story of Molly Pitcher, a single heroic woman who supposedly took over a cannon when her husband fell, may have been created to represent several women . The best documented candidate is Mary Ludwig Hays, but the legend also reflects the broader contributions of women who supported troops during the Revolutionary War, with or without having been widowed.

Davy Crockett died fighting to the last at the Alamo

Image: Eric Francis

Did Crockett heroically fight to the death amid hand-to-hand combat at the Alamo? Well, that was indeed the location of his death, but sources conflict about the manner.

Some eyewitness accounts and Mexican records suggest he may have been captured and executed; other accounts describe him dying in combat. The neat heroic portrait was shaped by 19th-century myth-making.

The Declaration of Independence was signed on July 4, 1776

Image: The New York Public Library

It is widely believed that all signers of the Declaration of Independence scribbled their names on it on July 4, which is why we celebrate that date.

Congress adopted the Declaration on July 4, but most delegates did not sign the parchment copy until August 2 of that year (and a few added their names even later). July 4 became the commemorative date for adoption and celebration, not the universal signing day.

The Pilgrims’ "First Thanksgiving" centered on a big roast turkey, like today

Image: Tyler Donaghy

No, the 1621 harvest meal at Plymouth did not feature the same turkey-centered feast we picture now.

Accounts mention venison and wildfowl, but the menu and ritual context were very different from modern Thanksgiving dinners. The idea of an annualized, turkey-centered national holiday developed much later (19th century onward).

10

Thomas Edison single-handedly invented the light bulb

Image: Tamas Pap

Many believe that Edison alone invented the incandescent light bulb out of whole cloth. But electric light was the product of decades of work by many inventors (from Humphry Davy to Swan and others).

Edison’s contribution was significant improvements and the critical development of a commercially viable, manufacturable system, but he did not "invent" electric light in isolation.

Pocahontas dramatically saved John Smith from execution

Image: EricThriller

The myth holds that Pocahontas heroically rescued Captain John Smith by throwing herself over him at the moment of execution.

Disney may have amplified the romantic and dramatic aspects of this story. John Smith’s account of a dramatic rescue appears in later writings and is debated by historians. Many scholars now interpret the scene as a ritual adoption or a ceremonial act rather than a literal rescue, or they suspect Smith embellished the story.
