While Cinco de Mayo is not officially a holiday, many U.S. communities celebrate Mexican culture and heritage on May 5 with parades, mariachi music, street festivals, and much more. Most celebrants, though, would probably not be able to tell you what really happened on that date.
After thrusting off centuries of Spanish rule in 1821, Mexico endured several decades of economic and political instability. In 1861, Mexican president Benito Juárez suspended payment of his country’s debts to France, Spain, and Great Britain. The three countries immediately sent warships to Mexico. Juárez negotiated with Spain and Britain and their ships went home. But French emperor Napoleon III saw an opportunity to expand his country’s colonial empire and landed troops at Veracruz. They planned on capturing Mexico City, the capital. The French army at that time was generally regarded as the world’s finest and anticipated little difficulty in reaching its objective.
With the Civil War having just begun, the US government couldn’t divert resources to Mexico. The first target of the invaders was the small town of Puebla de Los Angeles. More than six thousand French troops, supported by cannons, assaulted a ragtag army of inexperienced, ill-equipped Mexican defenders about half that size on May 5, 1862. Somehow the Mexicans overcame their disadvantages and defeated the French.
The following year Napoleon dispatched more than 30,000 soldiers to Mexico. They seized control and installed Austrian archduke Ferdinand Maximilian as emperor of Mexico.
When the Civil War ended in 1865, the US leaned on France to leave Mexico. The final French troops departed two years later. Mexican forces seized Maximilian and executed him.
Today Cinco de Mayo barely causes a ripple in Mexico outside of the province of Puebla. It is not a national holiday so nearly everyone goes to work as usual.
It’s a much bigger deal in the United States, which may be fitting. Some historians believe that if the French had not been defeated at Puebla de Los Angeles and seized Mexico City, Napoleon would have made an alliance with the Confederate States. The Civil War was not going well for the Union at that time and French assistance could well have swung the conflict in the South’s favor. The result would have been two separate nations.
Jim Whiting has written a biography of the Spanish explorer Hernando Cortés. To some people, he was heroic. Even though he was greatly outnumbered, he was able to defeat the Aztec Emperor Montezuma and conquer the Aztec empire centered in modern-day Mexico. To others, including many Mexicans, he was a villain because he destroyed the Aztecs way of life. They believed he was a cruel man. He was also a symbol of Spanish domination.

The great Paris tower was underway. From each corner of a broad base the size of a football field, four spidery iron structures rose, curving inward in one majestic sweep toward the middle. The construction – a web of connecting girders – called for 300 workers to assemble some 15,000 pieces of iron and snap 2.5 million rivets into place. This would be the world’s tallest man-made structure, reaching a height of 300 meters (934 feet). A glorious demonstration of engineering, it was conceived by Gustave Eiffel, the most illustrious engineer of nineteenth-century France.
The tower was to be the focal point of the International Exhibition of Paris in 1889, commemorating the 100th birthday of the French Revolution. After that, since it had no practical use, it was to be torn down.
It took two years, two months, and three days to build the Eiffel Tower. Eiffel used wrought iron, which was a relatively new building material at the time, used primarily for bridges and aqueducts. As the tower rose, becoming the city’s most prominent feature, not everyone approved. “Useless and monstrous,” one newspaper called it. Another described it as an “odious column of bolted metal.”
Called the Magician of Iron, Eiffel’s mathematical prowess and attention to detail was legendary. To put the tower project on paper took 30 draftsmen working full time for 18 months. Every rivet of the 2.5 million needed for the structure had its designated place, down to a fraction of a millimeter.
The Tower became the hit of the International Exhibition, with nearly two million people visiting it. Still, not everyone loved this prodigious web of steel girders. A famous writer was once asked why he ate lunch there every day, since he was known to hate the sight of it. He replied, “Because it’s the only place in Paris where I can’t see the damn thing.”
So why wasn’t the Eiffel Tower torn down? It almost was. What saved it was the radio broadcasting center and the weather station that Eiffel installed at the top.
Now France’s most famous landmark, it is not the only national symbol that Eiffel was involved with. He also built the iron skeleton of a lady we’re all familiar with: The Statue of Liberty.
As for the Eiffel Tower, “I ought to be jealous of that tower,” he once said. “She is more famous than I am.”

Eiffel's most famous works are still major tourist attractions in the 21st century. The Eiffel Tower is the most-visited paid monument in the world. An average of 25,000 people ascend the tower every day. Approximately four million people visit New York's Statue of Liberty National Monument and Ellis Island each year.

The Master Chef of Kids' Hands-on Science
In October, 1891, 23-year-old Manya Sklowdowska arrived in Paris to attend the Sorbonne, France’s great university. She had saved money, working as a governess to get there. She was determined to make the most of her studies in science and math. Right away she was noticed partly because she was Polish, although she had changed her first name to a French version, Marie, to fit in better. She always sat in the front row of all her classes because her French was not yet fluent and she didn’t want to miss anything. She also was one of only a few female students. In a university full of smart people, she worked hard to excel. She ultimately finished first in her class and went on to make major scientific discoveries.
What made Marie so single-minded and determined? Behind it all was a great love for science, a love she shared with her husband, Pierre Curie, whom she met in 1894. At that time, science was uncovering unimaginable truths in chemistry and physics. New discoveries were being made at a breath-taking pace. Science was like a game and it attracted many players. Why?
1. There was a Nobel Prize for winners, those who discovered a big idea about the natural world. There was only one nature to discover but people came at it from many directions.
2. It was collaborative—scientists shared their discoveries by publishing papers.
3. It was competitive—the papers described procedures so that scientists could check each other’s work. It kept everyone honest. The best work got the most attention.
4. The discoveries could be applied to solve problems for people. X-rays, light bulbs, phonographs, photographs, movies, and telephones would not have been possible without science.
5. The biggest prize was the idea of the atom and its structure. Many scientists contributed to modern atomic theory, including Marie.
Marie Curie won the Nobel Prize twice for her work. At a time when women didn't even have the right to vote, she was a working mother of two daughters, a single mother after she was widowed in 1906, the founder of the Radium Institute for research and she brought the x-ray to the battlefield in WWI. She believed that science could save the world, that scientific discoveries belonged to everyone. And she refused to benefit financially from her discoveries. She lived by the highest principles of honesty and integrity. She was a true champion of the science game.
DK Biography: Marie Curie tells the story of the discoverer of radium, from her childhood in Warsaw, to her experiments with radioactivity in Paris, to her recognition as one of the preeminent scientists of her time.
Filled with archival photographs and amazing fact boxes, this biography paints Marie Curie as the brave and brilliant scientist that she was.

Bessie Coleman, better known as Queen Bess, was America’s first black woman pilot. Born in Texas in 1892, into a world of extreme poverty and deepening racial discrimination, her dream to “amount to something one day” was fought against overwhelming odds. Working as a manicurist in a Chicago barbershop, she read about World War I pilots. She decided that she wanted to become a pilot. But she was met with the reaction: “You, a Negro and a woman—you must be joking.”
Undeterred, Bessie sought the advice of a valued customer in the barbershop. “Go to France,” he said. “The French are much more accepting of both women and blacks— but first learn the language.”
That same day, Bessie began taking French lessons. A few months later, she sailed for France, and signed up with an aviation school. Her training included everything from banked turns and looping-the-loop to airplane maintenance. In 1921, she became the first black woman to earn a pilot’s license.
Back in the U.S., an African-American woman pilot was big news. Thunderous applause and a rousing rendition of “The Star-Spangled Banner” greeted Bessie at her first airshow in New York. Memphis and Chicago followed. Bessie’s future never looked brighter. She managed to buy an old Curtis Jenny, a favorite plane among barnstormers. She was heading for a performance in Los Angeles, when the engine stalled; she crashed onto the street below, was knocked unconscious, broke one leg, and fractured several ribs.
Distraught over having disappointed her fans, she sent a telegram to the local newspaper: AS SOON AS I CAN WALK I’M GOING TO FLY! Seven months later, she was back in a borrowed plane, performing to upbeat crowds in Ohio, Texas, and Florida.
Bessie loved flying and accepted its risks, but her real ambition was to open a flight school. Sadly, she didn’t live to see her dream realized. In 1926, her old, run-down plane went into a spin. Bessie was thrown out of her seat, and fell to her death.
At her funeral, thousands paid their respects to the brave young aviator. With her pluck and determination, Bessie Coleman had set an example for many black people.
Shortly thereafter, the Bessie Coleman Aero Club in Los Angeles became a reality, introducing young blacks to the world of aviation. Among those inspired by Bessie was Dr. Mae Jemison, the first woman African-American astronaut.

Celebrating the History of Science
and the Science behind History
During the Renaissance, French kings and queens built many palaces, in an area known as the Loire Valley. The royal family would travel from palace to palace to get away from Paris, the way you might head to a lake house. The Loire Valley is not very close to Paris. It’s about 110 miles from Paris to the palace of Chambord, for instance. I wondered how long it took sixteenth century travelers to make this journey—and why there were so many palaces.
First, the distance. Under the best of conditions (good roads, decent weather, level ground), humans can walk four miles per hour over long distances. Horses can’t do much better–maybe five mph—but a lot less if they’re pulling something or if roads are in awful condition. A horse can canter at 20 mph, but it can only do that for six to eight miles at a time, after which it will slow down and walk, or stop completely. So it would have taken a long time to get from place to place. Under the best conditions, a journey from Paris to Chambord would have taken three weeks.
But in fact, it took a lot longer than that. Because in the sixteenth century, the royal court didn’t just hop on a horse and head to their country home. They took everything and everyone with them, loading all the stuff onto the backs of horses and mules.
When Catherine de Medici was queen of France, she traveled with her ladies and gentlemen, foreign ambassadors, pet bears, servants, retainers, attendants, apothecaries, astrologists, tutors, musicians, cooking pots, food, clothing, portable triumphal arches, wall hangings, and furniture.
And the reason there were so many palaces is simply that the court in Renaissance times –thousands of people–had to move around from estate to estate so as to find new hunting grounds. Once they’d exhausted the food supply in the area, they moved on to the next estate. Also, the sanitation was dreadful. After thousands of people had taken up residence in and around a great estate for a few weeks, filth piled up, and with it, stench and disease.
The royal procession could be miles long. When Catherine de Medici’s court packed up and left for a new palace, the beginning of the royal caravan sometimes entered a town before those traveling at the back of it had left the last one.
