If you’re looking for a clean, single date for when was tungsten discovered, you’re probably going to be a little disappointed. Science is rarely that tidy. Most textbooks will point you toward 1783, but that’s only half the story. It’s actually a tale of two brothers, a legendary Swedish chemist, and a rock that was so heavy it confused everyone who touched it for centuries.
Honestly, people knew something weird was going on with certain minerals long before they had a name for it. Miners in the Ore Mountains of Saxony noticed a mineral that frequently showed up alongside tin ore. It didn’t just sit there, though; it actually ate the tin during the smelting process, turning it into a useless dross or foam. They called it wolf ram, which literally translates to "wolf’s froth." It was like a wolf devouring the valuable metal. That’s why, if you look at a periodic table today, tungsten is represented by the letter W.
The Swedish Connection: Scheele’s 1781 Breakthrough
Before the metal was actually isolated, a guy named Carl Wilhelm Scheele—one of the most underrated scientists in history—stepped up. In 1781, working in Köping, Sweden, Scheele was messing around with a mineral then known as tungsten (which in Swedish means "heavy stone"). Today, we call that specific mineral scheelite in his honor.
Scheele was brilliant. He managed to extract a new acid from this heavy stone, which he called tungstic acid. He was fairly certain there was a brand-new element hiding inside that acid, but he didn't have the furnace capacity to blast it with enough heat to get the pure metal out. He basically handed the baton to the rest of the scientific community.
He published his findings, proving that this wasn't just some weird version of tin or iron. It was its own thing. But since he didn't actually produce the metal itself, the "discovery" date is often debated.
1783: The Elhuyar Brothers Finish the Job
This is where the story shifts to Spain. Two brothers, Juan José and Fausto Elhuyar, were studying under the same professors as Scheele. They took the "wolfram" mineral from a mine in Saxony and realized it contained the exact same acid Scheele had found in his "heavy stone."
They were working at the Seminary of Vergara. In 1783, they did what Scheele couldn't. By reducing the tungstic acid with charcoal at incredibly high temperatures, they isolated the pure metal for the first time. They found a dark, heavy, metallic powder.
They are the ones who officially get the credit for the discovery of the element in its metallic form.
Why Tungsten Is Actually Kind of a Freak
You have to understand how different tungsten is from other metals discovered in the 18th century. It has the highest melting point of all known elements in their pure form. We are talking 3,422°C (or 6,192°F). To put that in perspective, the surface of the sun is about 5,500°C.

It’s also incredibly dense. If you hold a cube of tungsten that's only two inches wide, it weighs about five pounds. It feels "wrong" when you pick it up—your brain expects it to be lighter.
The Branding War: Tungsten vs. Wolfram
For a long time, there was a massive naming dispute. The British and French liked "tungsten," following Scheele’s lead. The Germans and much of Northern Europe insisted on "wolfram."
In 1949, the International Union of Pure and Applied Chemistry (IUPAC) officially ruled in favor of "tungsten." However, the Germans weren't thrilled, and the chemical symbol remained W. So, we live in a world where we call it tungsten, but we write it down as wolfram. It's a linguistic stalemate that has lasted for decades.
How It Changed the World (Beyond Lightbulbs)
Most people only know tungsten because of Thomas Edison. While he didn't discover when tungsten was first found, he (and his team) eventually realized it was the perfect filament for lightbulbs because it could get white-hot without melting.
But its real impact is in war and industry. During World War II, tungsten became one of the most sought-after commodities on Earth. Because it’s so hard, it’s used in "armor-piercing" rounds. If you want to punch a hole through a tank, you use a tungsten core. It’s also what makes high-speed steel possible. Without tungsten, our CNC machines and lathes couldn't cut through other metals at high speeds because the friction would melt the tools.
What We Get Wrong About the Discovery
A common misconception is that tungsten was "invented." You don't invent elements; you find them. Another mistake is thinking the Elhuyar brothers found it by accident. They didn't. They were highly trained chemists specifically looking for the "hidden" metal Scheele had predicted.
Also, don't assume that once it was discovered in 1783, it was used immediately. It actually sat around as a scientific curiosity for nearly 100 years. It wasn't until the mid-19th century that Robert Mushet started alloying it with steel, realizing it made the steel much tougher.
Practical Takeaways and Next Steps
If you’re researching this for a project or just out of pure curiosity, here is the breakdown of what matters:

- 1781: Carl Wilhelm Scheele identifies tungstic acid in "heavy stone."
- 1783: The Elhuyar brothers isolate the metallic element for the first time in Spain.
- The Symbol: Always remember the W stands for Wolfram, the German name for the ore.
- Key Property: Melting point is the highest of all elements, which is why it's in everything from rocket nozzles to TIG welding electrodes.
To truly understand the impact of this discovery, you should look into the history of "High-Speed Steel." It changed manufacturing more than the lightbulb ever did. You can also look into current "conflict minerals" reports; because tungsten is so vital for vibration motors in smartphones and aerospace tech, its modern supply chain is just as dramatic as its 18th-century discovery.
