Federal holiday

Every year in America, we celebrate Martin Luther King Jr. Day on the 3rd Monday of January. This date was chosen because MLK was born on January 15, 1929, which fell on a Thursday.

But did you know that MLK Day is the only US federal holiday that celebrates the birthday of someone who wasn't a US president? Can you guess what the other one is? That’s right—it’s Presidents’ Day, observed on the 3rd Monday of February in honor of George Washington’s birthday.

Not afraid

If there’s one thing that defines MLK, it’s his bravery. And just as he was not afraid to confront the oppressive norms of his time, neither was he afraid of jail. In fact, he was arrested between 25 and 30 times, always for reasons related to his nonviolent activism.

It was during one of these arrests, in 1963, that he wrote his famous Letter from Birmingham Jail.

Improvisation

Martin Luther King Jr.'s " I Have a Dream" speech remains one of the most famous speeches in the world to this day. Those powerful, inspiring words could only come from a brilliant mind. But did you know that part of his speech was improvised?

That's right! On August 28, 1963, MLK impressed the world from the Lincoln Memorial steps with a carefully prepared speech, but he also added spontaneous thoughts inspired by the excitement of the moment. In fact, the speech's most famous words—the ones that gave it its title—weren’t part of the original draft.

MLK was also someone who appreciated quality TV. He was known to be a fan of the original Star Trek series.

But he wasn't just a fan—he went on to influence the show! Actress Nichelle Nichols, best known for playing Lieutenant Uhura, was about to leave the show, but she met King, and he encouraged her to stay. He believed that Nichols' role was crucial in inspiring young African Americans.

Birth name

The famous Martin Luther King Jr. was born on January 15, 1929, as Michael King Jr. in Atlanta, Georgia, named after his father, Michael King Sr. However, a few years later, that would change.

In 1934, after learning about Martin Luther, the leader of the Protestant Reformation, Michael King Sr. decided to change both his own name and his son’s to Martin Luther King Sr. and Martin Luther King Jr., respectively.

Martin Luther King Jr. skipped several grades and entered college at the young age of 15! Given his remarkable intelligence, this isn’t surprising, but his brilliance never fails to impress.

In 1944, he was admitted to Morehouse College in Atlanta, where he earned a Bachelor of Arts degree in Sociology. His studies there helped shape his critical perspective on society and its dynamics. Additionally, it was during his time at Morehouse that he decided to become a minister.

Time magazine's Person of the Year (originally called "Man of the Year") debuted in 1927, with American aviator Charles Lindbergh gracing the cover.

It took 36 years for the first African American to earn this recognition. Of course, that honor went to Martin Luther King Jr., who was named Person of the Year in 1963 , following the historic March on Washington and his unforgettable " I Have a Dream " speech.

His impressive career, filled with groundbreaking achievements, might lead us to believe that he had many years to achieve all of it.

However, the minister was still a young man when he was tragically attacked on April 4, 1968, in Memphis, Tennessee. Sadly, Martin Luther King Jr. lived to be only 39 years old.

Even if she was born in 1897, Amelia is considered a key figure of the 20th century because she was an aviation pioneer . As such she broke several records: She was the first woman to fly solo across the Atlantic and the first to promote commercial air travel.

But that wasn’t all, Amelia was an activist for women’s rights and wrote best-selling books narrating her adventures as a pilot. The mysteries behind her disappearance during her flight across the Pacific only made her a bigger icon.

Most of the professions held by the women in this article are accepted for women today, but not so long ago, being a woman and a successful businessperson wasn’t very common: That was the case with Estéé Lauder who launched her eponymous cosmetics company with her husband.

Influential and controversial depending on who talked about her, she was living proof that there is no such thing as bad marketing: All things considered, she still was the best-paid Hollywood actress of the time.

No article about influential women of the 20th century would be complete if we didn’t mention Rosa Parks.

In 1955, she refused to give her seat on a bus to a white passenger. Her courageous act of defiance sparked the Montgomery Bus Boycott and initiated the modern Civil Rights Movement. With a simple, but huge action, she challenged the whole system of racial segregation and inspired a nationwide movement for equality.

The bus boycott was the beginning, yet her work continued beyond that as she fought tirelessly for civil rights for the rest of her life.

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.

1859: First commercial well

Image: Provincial Archives of Alberta

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.

1860s–1870s: Pennsylvania oil rush

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.

1890s: Dawn of the automobile

Image: Matthew Lancaster

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.

1900s–1910s: Rise of big oil companies

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.
