Louis Renault: From genius to traitor (the most unjust story)

It's December 24, 1898, and it's freezing cold in Montmartre, and on Rue Lepic—you know, that street so steep it makes even modern cars sweat—a 21-year-old man is about to take on a completely crazy bet. He's built a kind of motorized tricycle in his mom and dad's garage, and there, in front of his brothers and a few friends drunk on New Year's Eve, he claims he's going to drive up that street. In 1898! At a time when horses still looked askance at these machines...

That night, this kid would bag his first 12 firm orders and unwittingly launch one of the largest automotive empires in history. But what he didn't yet know was that his meteoric rise would end in the most dramatic way possible : in a prison cell, accused of treason. Today, I'm telling you the story of Louis Renault, from genius tinkerer to captain of industry, and believe me, it's quite a journey.

The little prodigy from Boulogne-Billancourt

Louis Renault was born in 1877 into a bourgeois Parisian family, and it quickly became clear that he was a kid like no other. At 8 years old—you heard that right, 8—he installed electricity in the family home . Honestly, at 8 years old, I barely knew how to tie my shoelaces, let alone install electricity... And that was just the beginning! At 10, he made his own camera. Seriously, was this kid a genius or what?

At 14, Louis convinced his parents to set up a real workshop for him at the bottom of the family garden in Boulogne-Billancourt. And there we go, hours and hours of tinkering, modifying engines, drawing up plans, and filing his first patents. I swear that if I had had this talent at that age, my mother would probably have locked me up for fear that I would blow up the house .

But anyway, let's go back to our Christmas Eve in 1898. Louis is now 21 years old and has just finished his first "voiturette," as they called it at the time. Basically, he took a De Dion-Bouton tricycle and tinkered with it from top to bottom. The result? A small, unassuming machine that will change history.

The bet that changed everything

So we're there, on Rue Lepic, and Louis says to his friends: "Guys, I bet my little machine will climb this hill without flinching." Can you imagine the scene? In 1898, cars were still science fiction for most people . His brothers Marcel and Fernand are there, a few friends too, and everyone is probably thinking they're going to witness a real crash live.

But no! Louis's little machine climbs Rue Lepic as if nothing had happened. And then, it's total euphoria. His friends can't believe it, and above all, they take out their wallets. Twelve firm orders with a deposit of sixty gold louis each! To give you an idea, at the time it was a small fortune, enough to see you through .

And that's when Louis made the decision of his life: he was going to become a car manufacturer. No more Sunday tinkering, now it's serious business!

The birth of a family empire

On February 25, 1899, barely two months after the famous bet, the three Renault brothers officially created their company: "Renault Frères." Marcel and Fernand each contributed 30,000 francs—a colossal sum for the time—and Louis contributed his genius and his patents. At first, he was only an employee in his own company, can you imagine?

But Louis had a secret ace up his sleeve: he had just invented the direct-drive gearbox. And that, my friends, was a revolution! All the manufacturers of the time were going to fight over this innovation. This little invention would earn him nearly 3.5 million francs in royalties until 1914 , enough to see him through, as they say!

The Renault brothers, kings of racing

Between 1899 and 1903, Louis and Marcel literally dominated the voiturette races. Paris-Trouville, Paris-Ostend, Paris-Bordeaux... they won it all! Imagine the atmosphere: two brothers fighting for victory at the wheel of their own creations . It was the heroic era of the automobile, when manufacturers proved the reliability of their machines by pushing them to the limit on the roads of France.

Orders poured in, and the small family business grew rapidly. In 1905, Renault received its first major order: 250 taxis! And then, it was no longer a matter of craftsmanship, but of true mass production . Louis Renault became the first French car manufacturer.

But here's the thing, in this success story, there's going to be a drama that's going to change everything...

The tragedy that changed everything

On May 24, 1903, during the Paris-Madrid race, the unthinkable happened. Marcel, 31, Louis's beloved brother, the one with whom he shared this all-consuming passion for speed, was killed at the wheel of his Renault. I can't even imagine the shock for Louis . His brother, his partner, his accomplice... gone in one fell swoop.

This tragedy would radically transform Louis Renault. The outgoing and cheerful young man became an authoritarian and harsh boss. He had Marcel's bust placed at the factory gates, like an eternal guardian , and would never again participate in a car race. Competition was over, finished.

At only 26, I imagine he might be thinking he'd better devote himself to something more... useful. And that's exactly what's going to happen.

You know what? My passion for vintage cars reminds me why I created my shop BernardMiniatures.fr . Because holding a little 1/43 scale Renault from the 1900s in your hands is a bit like touching that heroic era with your fingertips. I have more than 1,500 miniatures in stock, mostly 1/43 scale, with a nice collection of Renault models - from the 1899 Type A to the 90s models. Well, I'm not a big site, so I often only have one or two pieces of each model, but that's also what makes it charming. Delivery is free from 75€ in France, and I take care to pack everything well because these little wonders break easily . Go take a look at bernardminiatures.fr if you're interested - you'll see, I have some gems that are really worth a look. Now, back to our Louis and his meteoric rise...

The genius inventor in the service of the nation

In 1914, war broke out and Louis Renault proved that his genius was not limited to cars. His factories contributed massively to the war effort by producing 7 million shells and aircraft engines . But the most famous episode was that of the famous "Taxis de la Marne".

September 1914, the Battle of the Marne rages. The French army needs to transport troops quickly. And so, 1,200 Renault taxis are requisitioned to take the soldiers to the front! Can you imagine the scene? Parisian taxis heading off to war!

The bill for heroic taxis

But here's the juicy detail: after this heroic operation, the French army had to pay 70,012 francs for the trips! The drivers had scrupulously run their meters according to the municipal regulations . To give you an idea, that would represent more than 23 million dollars in today's dollars! Frankly, I love this story - even in times of war, taxis are still taxis!

But Louis didn't stop there. In 1917, he took command of his own war tank, the Renault FT. On February 22, 1917, he himself led the tests of this new weapon he had just designed . 3,700 units were built in 18 months, and this revolutionary tank would define the model for the modern combat tank until 1940.

The interwar empire

The 1920s and 1930s were Louis Renault's heyday. In 1929, he opened the ultra-modern Île Seguin factory in Boulogne-Billancourt , a famous factory that would become the symbol of the French automobile industry. His empire covered 100 hectares and employed 38,000 people in 1939!

During his career, Louis filed more than 500 patents. 500! I, who have trouble dropping off a simple package at the post office without getting the address wrong... This man was an inventive machine, a true industrial genius.

The Eternal Perfectionist

You know what impresses me most about Louis Renault? He never lost that tinkerer's soul from his early days . Even at the head of his empire, he continued to get his hands dirty, improve his machines, and rethink every detail. This guy was literally obsessed with technical perfection.

But all good stories have an end, and Louis Renault's is going to be particularly dramatic...

The Fall of the Giant

1940, France is occupied. Louis Renault, like many industrialists of the time, finds himself in an impossible situation : continue to operate his factories under German occupation or see his 38,000 workers unemployed and his facilities destroyed. He chooses to continue production.

But at the Liberation, this decision would cost him dearly. On September 23, 1944, Louis Renault was arrested and accused of collaborating with the enemy . The man who had given so much for France during the First World War found himself in a prison cell.

A death in the shadows

A month later, on October 24, 1944, Louis Renault died in prison at the age of 67. The circumstances of his death remain controversial to this day . He was never able to defend himself, never able to explain his choices.

In January 1945, his company was nationalized and became Régie Renault. The empire he had built with his own hands was lost to him for good . It was probably one of the most unjust endings in French industrial history.

The legacy of a visionary

Today, when you drive a Renault, you're still driving a bit with the legacy of this kid who tinkered in the family garage in Boulogne-Billancourt . From the 1899 Type A to current models, there's a direct lineage with this little genius who had the audacity to bet that he could go up Rue Lepic one Christmas Eve.

Louis Renault will have marked the history of the French automobile industry like few men have done. From tinkerer to captain of industry, he will have lived a thousand lives in one , known the greatest triumphs and the most brutal fall.

Its story reminds us that behind every great car brand, there is often a man or woman who dared to dream bigger, who had the nerve to believe in their ideas when everyone else doubted them. And that, frankly, is beautiful .

That's why I love telling these stories and collecting these little cars that carry all these memories within them. Because, deep down, each miniature tells the story of a dream come true .
