How Tennis Was Invented

Listen in Sam's voice (generated with ElevenLabs)

Hey kids! Buckle up, because today we’re going on a wild adventure back through time to discover how one of the most exciting sports in the world was invented. I’m talking about tennis!

But here’s the thing — tennis didn’t start with rackets on a grass court. It started with… monks hitting balls with their bare hands.

That’s right. About eight hundred years ago, in medieval France, bored monks living in monasteries started playing a game in their courtyards. They’d hit a ball back and forth over a rope stretched across the ground, smacking it with the palms of their hands. The French called it “jeu de paume” — which literally means “game of the palm.” They weren’t messing around either. These monks were seriously competitive.

Word spread fast. Pretty soon, everyone in France wanted to play. Kings played it. Nobles played it. They built special indoor courts with sloped roofs and weird angles. This fancier version became known as “real tennis” — and yes, that’s actually what they called it. Real tennis. Because eventually they needed a way to tell it apart from the new game that was coming.

Eventually people started using gloves to protect their hands. Then paddles. Then rackets with strings made from sheep gut. They stretched a net across the middle of the court instead of just a rope. The sport kept evolving.

But here’s where things get really interesting. Jump forward to England, 1873. A British Army Major named Walter Clopton Wingfield was planning a garden party at his country estate in Wales. He wanted a fun outdoor game his guests could play on the freshly mowed lawn. So he did something amazing — he invented one.

Major Wingfield patented the game of lawn tennis. He sold it in a box that included a net, rackets, balls, and a rulebook. He called it by a fancy Greek name: Sphairistike. Which means… “ball game.” Not exactly the catchiest name. Nobody could pronounce it, and people just started calling it lawn tennis instead.

The timing was perfect. It was the Victorian era. Everyone was obsessed with being outdoors. Croquet was the big lawn game at the time, but lawn tennis was faster, more exciting, and way more athletic. It spread like wildfire.

Just four years later, in 1877, a place called the All England Club in Wimbledon decided to hold the very first lawn tennis championship. Twenty-two men entered. A guy named Spencer Gore won the whole thing. And here’s a fun fact: that tournament is still going today. Wimbledon is now the oldest and most prestigious tennis tournament in the entire world. The grass courts, the white outfits, the strawberries and cream — it all traces back to that first championship in 1877.

Now, I know what you’re wondering — why does the score go 15, 30, 40? Why not just 1, 2, 3?

Great question! Nobody knows for absolute certain, but one popular theory goes back to medieval clock faces. Clocks used to be divided into quarters — 15, 30, 45, 60. Early tennis players may have used the clock face to count points. So the first point was 15, the second was 30, the third SHOULD have been 45 — but somewhere along the way, people shortened it to 40 because it was easier to call out quickly. And then you need one more point to win the game. Makes sense in a weird medieval way, right?

And what about “love” meaning zero? Why on earth would love mean nothing?

That one probably comes from the French word “l’oeuf” — which means “the egg.” Think about it. An egg looks like a zero. So when French players had no points, they’d say “l’oeuf” — the egg. And when the sport spread to England, the English heard “l’oeuf” and started saying “love.” So when you’re watching a tennis match and hear “love-fifteen” — you’re actually hearing a five-hundred-year-old joke about eggs.

One more fun fact before we wrap up: why is the tennis ball yellow? Well, tennis balls used to be white. For a really long time, they were white. But in 1972, Wimbledon and television companies realized something — white balls were really hard to see on TV screens. So they switched to a bright optic yellow, which pops on camera. Though here’s the twist: Wimbledon stubbornly kept calling them white for years. They were clearly yellow. Everyone could see they were yellow. But officially, Wimbledon insisted: white. Finally in 1986, they gave up and admitted: yes, the balls are yellow.

From medieval monks playing handball in monastery courtyards, to a British Army Major selling a game in a box, to Wimbledon and its yellow balls — tennis has had one of the most amazing journeys of any sport ever invented. And next time you pick up a racket and swing away, you’re carrying on a tradition that’s nearly a thousand years old.

Pretty cool, right?
