Paul Héroult (born April 10, 1863 – died May 9, 1914) was a very clever French scientist. He helped invent a special way to make aluminium much cheaper. This method is called the Hall–Héroult process. He also created the first successful electric arc furnace, which changed how we make steel.

Paul Héroult's Big Ideas
Paul Héroult was only 15 years old when he read a book about aluminium. Back then, aluminium was super expensive, costing as much as silver. It was mostly used for fancy jewelry and luxury items. Paul really wanted to find a way to make it cheaper for everyone.
He worked hard and succeeded in 1886. He discovered a new way to make aluminium using electricity. This process is called electrolysis.
The Hall-Héroult Process
In the very same year, 1886, an American scientist named Charles Martin Hall (1863–1914) discovered the exact same process in the United States. Because both Paul Héroult and Charles Martin Hall found this amazing solution at the same time, the method is now known as the Hall–Héroult process. This invention made aluminium much more affordable and useful.
Inventing the Electric Arc Furnace
Paul Héroult's second big invention was the first successful electric arc furnace (EAF) for making steel. He developed this in 1900. Before this, making steel was a much harder process.
The electric arc furnace uses a powerful electric spark to melt metal. This invention slowly replaced older, giant furnaces. It made it easier to produce many different types of steel.
In 1905, Paul Héroult was invited to the United States. He worked as an expert for several companies, including the United States Steel Corporation. The first Héroult furnace in the US was set up by the Halcomb Steel Company.
How the Electric Arc Furnace Started
The idea for the electric arc furnace began a long time ago. In 1800, Humphry Davy discovered the carbon arc, which is like a strong electric spark. Later, in 1878, Carl Wilhelm Siemens created and used early versions of electric arc furnaces. But they needed more electricity and better carbon parts to work well for businesses. Paul Héroult made these furnaces practical for everyday use.
Other Cool Inventions
Paul Héroult is also known for other clever inventions. One of them is a special pipe system that can carry water down from mountains and across rivers. This system doesn't need expensive bridges to support it. It's still used today for hydraulic power plants, which make electricity from water.
Paul Héroult passed away on May 9, 1914, shortly after his 51st birthday.
