April 20th Through Time: Birthdays, Breakthroughs & Delightful Surprises

On April twentieth, nineteen sixty-four, the very first jar of Nutella left the factory in Alba, Italy. And just as we talked about last time with the invention of the postage stamp, it’s a powerful reminder that sometimes the simplest, most unassuming things can quietly take over the world. That first jar of chocolate-hazelnut spread was a delicious promise of what was to come. But what’s truly remarkable is what else was happening on that same day, across the years. April twentieth is a date that seems to collect stories. It’s a date of scientific genius, of terrible tragedy, of revolution, and of...

well, of a certain kind of celebration. Looking back, it’s a calendar day that feels like a cross-section of humanity itself. A day that holds creation and destruction, side by side. We just have to be willing to look at it all at once. And what a collection it is. On this day, we celebrate the birthdays of some absolute titans of the screen and stage. Jessica Lange, born in nineteen forty-nine, a force of nature who has won two Oscars, a Tony, and multiple Emmys. Ryan O’Neal, born in nineteen forty-one, the unforgettable star of Love Story and Paper Moon. And the velvet voice himself, Luther Vandross, born in nineteen fifty-one.

These are people who shaped the emotional landscape of their time. But April twentieth is also a day of profound discovery. On this day in nineteen-oh-two, a husband and wife working in a drafty shed in Paris finally succeeded. Marie and Pierre Curie isolated the radioactive element radium. They had found something that glowed in the dark, something that seemed to defy the laws of physics by producing its own energy. And in that moment, they didn't just discover an element; they unlocked a door. A door that led to nuclear physics, to new cancer treatments, but also to the atomic bomb. They couldn't have known it then, but in that small, glowing sample, they were holding so much of the twentieth century’s promise… and its peril.

Fast forward over a century, to April twentieth, twenty twenty-three. Another kind of explosive discovery. SpaceX launched its massive Starship rocket, the most powerful ever built. And four minutes into the flight… it spectacularly exploded. Now, from the outside, that looks like a failure. A very expensive firework. But from the perspective we have now, looking back, that was the point. The engineers weren't trying to get to orbit. They were trying to see what would break. They called it a "rapid unscheduled disassembly," and they celebrated. Because every piece of data from that explosion was a lesson learned, a step closer to their goal of getting humanity to Mars.

It was a failure that was actually a success. But not all the explosions on this date are so easily reframed. On April twentieth, two thousand and ten, the Deepwater Horizon oil rig exploded in the Gulf of Mexico. Eleven workers were killed instantly. For eighty-seven days, oil gushed into the ocean, creating the largest accidental marine oil spill in history. That date isn't a marker of progress. It’s a scar. It’s a permanent reminder of the cost of our dependence on fossil fuels, and the catastrophic price of corporate negligence and regulatory failure. And then there is the event that has permanently stained this date in the American consciousness.

April twentieth, nineteen ninety-nine. Columbine High School. Two students walked into their school and created a nightmare that has never really ended. It wasn’t the first school shooting, but it was the one that burned itself into the national psyche. It created the blueprint for the horrors that would follow, and it began a conversation about guns, and mental health, and media, that we are still, decades later, failing to resolve. It’s a day of profound and lingering grief. So we have Nutella. We have radium. We have a rocket and an oil spill and a massacre. What else could this day possibly hold? How about a revolution?

Because on April twentieth, eighteen seventy-six, the Bulgarian April Uprising began. For nearly five hundred years, Bulgaria had been under the rule of the Ottoman Empire. This was not just a protest. This was a desperate, heroic, and ultimately doomed attempt to throw off centuries of domination. The revolutionaries knew they were outnumbered and outgunned. They knew they would likely fail. And they did. The uprising was crushed with shocking brutality. Thousands were killed. But here’s the turn. Here’s what makes this a story a historian loves. The sheer violence of the Ottoman response horrified the world.

Journalists and diplomats across Europe, people like Victor Hugo and William Gladstone, raised an outcry. The "Bulgarian Horrors" became an international cause. And that public pressure, that moral outrage, is what directly led to Russia declaring war on the Ottoman Empire the following year. That war—the Russo-Turkish War—ended with the Treaty of San Stefano, which established an independent Bulgarian state. So looking back, was the uprising a failure? Absolutely not. It was a strategic sacrifice. The leaders knew they couldn't win on the battlefield, so they chose to win on the battlefield of public opinion.

They lost the battle, but in the most profound way, they won the war for their nation’s freedom. It’s a stunning example of how history’s ledger is not always balanced in the moment. Sometimes, the meaning of an event is only revealed by what comes after. And that brings us to the other, very different, underground movement that claims this date. While one part of the world was forging a nation through blood and fire, another kind of code was being born in California. And it started, as so many great stories do, with five teenagers. In nineteen seventy-one, in Marin County, a group of high school friends who called themselves "the Waldos"—because they used to hang out by a wall—heard a rumor.

A local Coast Guard member had supposedly planted a patch of cannabis somewhere out in the Point Reyes wilderness and could no longer tend to it. He gave them a treasure map. So, the Waldos decided to go looking for it. They needed a time and a place to meet after their sports practices were done. They settled on 4:20 PM, at the statue of Louis Pasteur that stood on their school campus. "Four-twenty Louis," was the initial call. It soon just became "four-twenty." They’d pile into a car, maybe smoke a little, and go hunting for this mythical field of free weed. They never found it. Of course they didn't.

But they kept the code. "Four-twenty" became their private joke, their shorthand for, well, you know. So how does a private joke between five kids become a global holiday? The answer is the Grateful Dead. One of the Waldos’ fathers handled real estate for the band, and another’s older brother was the manager for their side project. The Waldos had access. They hung out backstage. And as they did, their slang, their little private code, started to spread through the Deadhead community, this massive, traveling network of fans. For years, it was just an insider term. But then, in nineteen ninety-one, a journalist for High Times magazine got ahold of a flyer at a Grateful Dead concert.

The flyer told the story of 4/20 and invited people to celebrate on April twentieth at 4:20 PM. High Times printed it. And that was it. The fuse was lit. The magazine started using the term, referencing it, and slowly, surely, it went from being a subculture secret to a global phenomenon. Think about the sheer improbability of that. A handful of kids, a statue, a treasure map, and a rock band. That’s the origin story. And now, April twentieth is a day recognized on six continents. It’s a day of protest in places where cannabis is illegal, a day of massive commercial celebration where it’s legal, and a quiet ritual for millions of people who just… light up at 4:20 PM.

Looking back, what we are actually seeing is the birth of a modern myth. It’s a piece of folklore created in real-time, its origins traceable right back to the source. It’s a rebellion, of a sort. Not a violent one like the Bulgarian Uprising, but a cultural one. A quiet, decades-long act of civil disobedience that has slowly, incredibly, become mainstream. So what do we do with a day like this? A day that holds the birth of Nutella and the discovery of radium? A day that marks a national revolution and a counter-culture holiday? A day that forces us to remember the horror of Columbine and the devastation of Deepwater Horizon?

Maybe we just accept that this is what history actually is. It isn't a clean narrative. It’s not a straight line. It's a messy, chaotic, contradictory pile of moments, all happening at once. It’s glorious and it’s terrible. It’s a story of human genius and human folly, of immense courage and unimaginable pain. Looking back from the future, we won't see April twentieth as "the Nutella day" or "the Columbine day." We'll see it as it is: a single, 24-hour slice of the human experience in all its impossible complexity. The value of a day like this is that it forces us to hold all of it in our hands at the same time.

The sweet, the bitter, the explosive, the radiant, the tragic, and the revolutionary. This is the pattern. This is what it means to be alive on the planet.
