Jacques Charles invented the hydrogen balloon.

The French chemist, physicist, and aeronaut Jacques Alexandre César Charles, was born November 12, 1746, in Beaugency, Loiret, France. Beginning as a clerk in the finance ministry, Charles turned to science and experimented with electricity. He developed several inventions, including a hydrometer and reflecting goniometer, and improved the Gravesand heliostat and Fahrenheit's aerometer.

He is best known for his formulation in 1787 of one of the basic gas laws, known as Charles's law, which states that, at constant pressure, the volume occupied by a fixed weight of gas is directly proportional to the absolute temperature. However, during his lifetime, Charles was better known for inventing the hydrogen balloon.

Jacques Charles and Ain‚ Roberts ascended over Paris in a hydrogen-filled La Charli're on December 1, 1783.

In 1783, realizing that hydrogen was lighter than air, he made the first balloon using hydrogen gas and, on August 27, 1783, the balloon ascended to a height of nearly 3,000 feet (914 meters).

Upon landing outside of Paris, it was destroyed by terrified peasants. On December 1, 1783, he, along with Ainé Roberts, ascended to a height of 1,800 feet (549 meters) in the newly constructed La Charlière. He was elected to the French Académie des Sciences in 1785. Charles died on. April 7, 1823, in Paris.
