On This Day, May 20, 1873, Levi Strauss and Jacob Davis received U.S. Patent No. 139,121 for creating the world’s first blue jeans reinforced with copper rivets.

The patent was issued by the United States Patent Office and would forever change fashion history.

Jacob Davis originally came up with the idea after customers needed stronger work pants that would not tear easily during hard labor. He added copper rivets to stress points like pockets and seams to make them more durable.

But Davis could not afford the patent fee alone.

So he partnered with Levi Strauss, a businessman who supplied fabric and ran Levi Strauss & Co.

Together, they created what would become the modern blue jean

Originally designed for miners, railroad workers, farmers, and laborers during the American industrial era, blue jeans eventually became one of the most popular clothing items in the world.

In the 1890s, the company introduced the legendary Levi’s 501 Jeans 👖

Today, Levi’s jeans are worn worldwide and remain one of the most iconic fashion inventions ever created.

A simple work pant that became a global fashion legend.

Happy Constitution Day Norway!

On This Day, on May 17, 1814, the Constitution of Norway was signed at Eidsvoll, marking one of the most important moments in Norwegian history.

Today, May 17, is celebrated as:
Norway’s Constitution Day

It is Norway’s national day and has been officially observed since 1814.

Across the country, Norwegians celebrate with:
🎉 parades
🎉 traditional clothing (bunads)
🎉 music and flags
🎉 and large public celebrations

Among Norwegians, the holiday is commonly called:
Syttende Mai (“17th May”)
Nasjonaldagen” (“National Day”)

A day that shaped modern Norway forever.

On This Day, on May 18, 1980, Mount St. Helens erupted in Washington State, causing the deadliest and most destructive volcanic eruption in United States history.

The eruption triggered:
🌋 a massive landslide
🌋 a powerful sideways volcanic blast
🌋 ash clouds reaching 80,000 feet
🌋 and widespread destruction across nearby forests and towns.

The disaster killed 57 people, including innkeeper and World War I veteran Harry R. Truman, photographers Reid Blackburn, Robert Landsburg, and volcanologist David A. Johnston, and destroyed hundreds of homes, roads, bridges, and millions of trees.

The eruption was so powerful that ash spread across multiple U.S. states, turning daytime into darkness in some areas.

Today, Mount St. Helens remains one of the most famous volcanic disasters ever recorded.

A mountain exploded… and an entire landscape vanished within minutes.

On This Day, May 15, 1902, American aviation pioneer Lyman Gilmore reportedly flew a steam-powered airplane at Grass Valley, California, more than a year before the Wright brothers’ historic flight at Kitty Hawk.

According to Gilmore, his unusual aircraft made a downhill takeoff, flew nearly 3 miles, and safely returned. The machine was powered by steam using a heavy boiler fueled by coal, making it one of the strangest aircraft concepts in early aviation history.

Lyman Wiswell Gilmore Jr. was born on June 11, 1874, in Washington, United States. Fascinated by flight from a young age, he spent years experimenting with engines, gliders, and early aircraft designs during a time when powered human flight was still considered nearly impossible.

Gilmore claimed to have successfully flown several experimental aircraft before many better-known aviation pioneers. However, his story remains controversial because almost all records, documents, and evidence related to his machines were destroyed in a devastating hangar fire in 1935.

Although photographs from 1898 show Gilmore standing beside his aircraft, no verified image exists showing the airplane in the air. Because of this, historians continue to debate whether he truly achieved powered flight before the Wright brothers.

Some believe he was a forgotten genius ahead of his time. Others believe the legendary flight never happened at all.

Lyman Gilmore died on February 18, 1951, at the age of 76. Today, he remains one of the most mysterious figures in aviation history.

A forgotten flight that may have changed aviation forever.

On This Day, May 13, 1862, Robert Smalls, an enslaved African American sailor, carried out one of the most daring escapes of the American Civil War.

Smalls secretly took control of the Confederate transport ship:

CSS Planter
While the white officers were ashore in Charleston, South Carolina, Smalls and the enslaved crew disguised themselves as Confederate sailors and successfully sailed the ship past heavily armed Confederate checkpoints during the night.

To avoid suspicion, Smalls wore the captain’s uniform and used the correct military signals while passing through Confederate defenses.

The Escape
After escaping Confederate waters, Smalls steered the ship toward Union naval forces and surrendered the vessel to the following:

⚓ United States Navy
On board the ship were:
enslaved crew members,
their families,
and valuable Confederate weapons and military intelligence.

The Union quickly commissioned the ship as:

USS Planter
Robert Smalls later became the first Black man to command a United States military vessel.

Historical Significance
Smalls became a national hero and later served as:
a Union Navy pilot,
a politician,
and a U.S. Congressman after the Civil War.

His courage and intelligence turned an escape from slavery into one of the most remarkable acts of the Civil War era.

Since 2023, the state of South Carolina has celebrated Robert Smalls Day every May 13.

A stolen ship that changed one man’s life and made history.

On this day, while the world celebrated the end of World War II, thousands of Algerians in Sétif, Guelma and Kherrata took to the streets and were met with bullets, bombings and mass executions. More than 45,000 martyrs fell at the hands of French colonial forces men, women and children, guilty only of demanding their freedom. 81 years later, France still refuses to call it what it was: a genocide. We remember. We transmit. We do not forget. 🇩🇿

On This Day, on May 10, 1915, Canadian physician Dr. Cluny MacPherson presented his gas mask invention to the British War Office Anti-Gas Department during World War I.

The invention came shortly after the German army used poison gas against Allied troops for the first time at the Second Battle of Ypres in Belgium on April 22, 1915.

The deadly gas attacks shocked the world and created an urgent need for protective equipment on the battlefield.

MacPherson’s design was one of the first effective gas masks developed for military use. The device, later known as the British Smoke Hood, covered the entire head and used chemical-treated fabric to help protect soldiers from poisonous gases.

The British Army officially adopted the design in June 1915, and more than 2.5 million units were produced within just a few months.

The invention marked a major turning point in modern warfare and military protection, as chemical weapons became one of the most feared threats of World War I.

Gas masks would later evolve into advanced protective equipment used by soldiers, firefighters, emergency responders, and civilians around the world.

An invention created to survive one of the deadliest new weapons of war.

On This Day, May 9, 1962, scientists successfully bounced a laser beam off the surface of the Moon for the first time in history.

The experiment was carried out by a team from the Massachusetts Institute of Technology, who used powerful laser pulses aimed directly at the Moon. The reflected light was successfully detected back on Earth, proving that laser communication and precise lunar distance measurements were possible.

This groundbreaking achievement became an important step toward future space research and lunar exploration.

The experiment later evolved into the Lunar Laser Ranging experiment, which measures the exact distance between Earth and the Moon using laser technology.

During the Apollo missions, astronauts placed special retroreflectors on the Moon’s surface:
Apollo 11 Moon landing
Apollo 14
Apollo 15

The Soviet Lunokhod program missions also placed reflectors on the Moon.

Today, scientists still use these reflectors to study the following:
the Moon’s movement,
Earth-Moon distance,
and even tiny changes in Earth’s rotation.

A beam of light that helped humanity better understand the Moon.
