François Isaac de Rivaz was a clever Swiss inventor and politician. He was born in Paris, France, on December 19, 1752. He passed away in Sion, Switzerland, on July 30, 1828.
Isaac de Rivaz is famous for inventing the world's first car. This car was powered by an "internal combustion engine" that used hydrogen gas. He described his invention in a French patent in 1807. In 1808, he put his engine into a simple vehicle, creating the first car to run on an internal combustion engine.

Isaac de Rivaz's Early Life and Education
Isaac was born in Paris, but his family came from Valais, a region in Switzerland. His father, Pierre de Rivaz, was a clockmaker and businessman. In 1763, Isaac's family moved to Moûtiers in Savoy. Later, Isaac and his brother Anne-Joseph settled in Saint-Gingolph.
We don't know exactly where Isaac went to school. But he was very good at subjects like Latin, mathematics, and geometry. He loved studying how things work (called mechanics) his whole life. He also worked for the government in Valais as a surveyor and a notary.
Isaac de Rivaz's Curious Mind and Inventions
Isaac was a very curious person with many interests. He loved to discover new things and try out new ideas. He experimented a lot with different inventions.
In the late 1700s, he worked on vehicles powered by steam. He also studied how to make gases burn to create power. These early experiments helped him later with his famous engine.
How Isaac de Rivaz Invented the First Internal Combustion Engine
After he retired from the army, Isaac de Rivaz lived in Switzerland. In 1807, he invented a basic internal combustion engine. This engine used a mix of hydrogen and oxygen gases. He lit the gases with an electric spark.
His engine was different from modern ones. It didn't squeeze the gases inside the engine. It also didn't use a crank or a connecting rod. A year later, in 1808, Isaac built an early automobile to hold his new engine. This made it the world's first car powered by an internal combustion engine.
Other Early Internal Combustion Engines
Around the same time, in 1807, another inventor named Nicéphore Niépce also created an internal combustion engine. His engine, called the Pyréolophore, used a mix of moss, coal dust, and resin as fuel. Niépce put his engine in a boat and sailed it on the Saone river in France. He even got a patent for it from Napoleon I.
So, Isaac de Rivaz's engine was the first to power a car in 1808. Niépce's Pyréolophore was the first internal combustion engine used in a ship in 1807.
Even though de Rivaz's work was very important, internal combustion engines didn't become common until much later. In 1824, a French scientist named Nicolas Léonard Sadi Carnot explained how heat engines work. He showed that engines needed to compress the fuel to make more power and be more efficient.
Gasoline was not used in these engines until 1870. That's when carburetors were invented. Carburetors help turn liquid fuels like gasoline into a gas that can burn inside the engine.
